Router problems, help requested

[Fly]

(Configuration: Sitecom router connected by wire to modem, wireless WPA-PSK connection from my router to USB adapter on my computer, the USB adapter uses Sitecom firmware, no other devices in network, Windows XP Home Edition service pack 2, Avira security suite trial)

A number of weeks ago I bought myself a new router. It worked fine till today or yesterday.

I'm not sure how I got myself into this mess. I switched between wireless to wired (cable/wire between computer and modem, bypassing the router) and back at least once.

I noticed some problems. I checked and noticed that the cable from my modem was plugged into the LAN slot of my router ! I put it back in the WAN slot, performed a factory reset, activated encryption and entered a new password.
(Actually I tried that in a number of variations, but I try to be brief here)

At first, I couldn't connect to the internet at all. Now, for the time being, I can, but it seems that browsing is sluggish.

The thing is: when I type IPCONGFIG /ALL I get this:
IP address 192.168.0.100
Subnet mask 255.255.255.0
Default gateway: 192.168.0.1
DHCP server 192.168.0.1
DNS server 192.168.0.1
Primary WINS server 192.168.0.1
(And a few other things that probably don't matter)
Earlier today I managed to get a 82.X IP address under IPCONFIG /ALL, but that didn't last, my last several attempts came up with the IPs as mentioned above.

Now things are weird.

If I log into the router, I see the above mentioned numbers at 'device status' and the word LAN is used.
At 'internet status' I get: Dynamic IP address, my real IP number (82.X), subnet mask 255.255.254.0, default gateway 82.Y ( a bit different from my real IP).

I can't say I like it this way. I don't understand it. I tried deactvating Avira, but that didn't help.
I'm not sure this is safe or stable.

This is not completely unlike the problems with my old router ( http://www.wilderssecurity.com/showthread.php?t=246945 ), but it is different.

It's a Sitecom router. I prefer not to post the exact model, or other personal/technical details, but I may be willing to send a PM if someone thinks that will help. There is actually a lot of information about this router, it uses some open source code and if you are tech savvy you can probably install a lot of software or use the router with your own code.
I can't do that ! (The manual on the CD didn't help)

As I stated, I don't like it this way, don't trust it this way, it's sluggish, and I don't understand why ipconfig /all now shows only LAN data. That's completely new. I can even do a config /renew with the router, which I never could do in the past.

I even tried restoring an older image, but that didn't solve this problem.

Any help with returning my router to its previous state (or an explanation) would be very much appreciated.

Try this:

01)- Power down the computer
02)- Unplug Modem
03)- Unplug Router
04)- Remove all network cables from all devices connecting computer to router to modem
05)- Plug in and power up the router and reset to factory defaults by pressing the reset button
06)- Unplug Router
07)- Power up the computer and log into your administrative account
08 )- Set the TCP/IP Properties to obtain an IP Address automatically
09)- Set the TCP/IP Properties to obtain an DNS Server automatically
10)- Remove any WINS Servers listed in the TCP/IP Properties WINS Tab and set the NetBIOS to Use Default
11)- Make sure the Network Connection Properties lists: Client for Microsoft Networks, QoS Packet Scheduler, File and Printer Sharing for Microsoft Networks, Internet Protocol (TCP/IP)
12)- From Device Manager, disable any Power Management features from the Properties of the Network Adapter
13)- Navigate to: Control Panel/Internet Options/Connections/LAN Settings/ -and uncheck all the boxes
14)- Power down the computer
15)- Plug the cables back into the devices, the Topology must be as follows:
(a)- Ethernet cable from modem to the WAN port of the router
(b)- Ethernet cable from Port one of the router to the Network Card of the computer

16)- Plug in and power up the modem and let stabilize
17)- Plug in and power up the router and let stabilize
18 )- Power up the computer and log into your administrative account and let stabilize
19)- From the Properties of the Local Area Network Connection choose: Repair
20)- Open the Command Prompt and type in: ipconfig /flushdns and press enter, after the conformation echo, close the Command Prompt
21)- Reboot the computer and log into your administrative account

Ouch ! :ouch:

Thank you, I tried that, but it didn't work.
I didn't have the Microsoft client installed, or file and printer sharing among networks, but other than that I had little or nothing to change in my computer settings.

Under 10): the router has LMHOSTS lookup enabled by (factory?) default. And NETBIOS by DHCP. Is that OK ?

15 b) I'm not sure what you meant. I have a wireless connection between my router and the USB adapter (with firmware) on my computer.
The first time I didn't put a cable between my router and the network card of my computer, because it didn't seem to make much sense. My router doesn't have a 'port one'. In the manual a WAN port is mentioned, but the other ports are not described as WAN or LAN. Anyway, I tried it (wireless) and it didn't work.
Next, I put a cable/wire between my router and the ethernet card on my computer. I removed the USB adapter. I think the ethernet card uses NVIDIA driver(s). It didn't work at all ! I lost my connection to the internet. I made the same changes with network connection and LAN things on the ethernet card, but that didn't work. What would actually be the point of that ? I don't need to use my ethernet card with my router.

For clarity, this computer has a built-in ethernet card, which I can use if I want to connect my computer to my modem by wire. For the wireless connection I have a USB adapter, no ethernet card.

I actually lost my connection to the internet, and it took me a lot of time to get it up and running again. (wireless) :ouch:

The router seems to have the correct LAN and WAN data (as it shows when I log in), and it seems to act as a firewall when I test it by disabling the software firewall.

I just don't know why I get that strange information when I type 'IPCONFIG /ALL'. I don't understand it and I don't fully trust it.

(10) Yes, those settings are correct

(15b) I need an hardwired connection from the router to the ethernet card of the computer.
I also need the wireless USB adapter disconnected (removed) from the computers USB port.
The ports on the router may not be labeled as WAN, LAN, ONE, TWO, ETC..
This is called troubleshooting, I need an hardwired connection from the router to the computer to test the router, connection, and
possibly re-flash the router firmware if needed.....wireless can be set up later.
Also note that an hardwired connection is much faster than an wireless connection. Also, flashing the router firmware should be done
through an hardwired connection rather than an wireless connection for reliability.
NVIDIA drivers are for video, you may be plugging the ethernet cable into the video card instead of the network card.


To further assist you I need the following:

01)- The make and model number of the router
02)- The make and model number of the computer

Without this information I can not diagnose the situation or the problem, you may send an Personal Message to me with this information.

Also, perform an manual Windows Update and check the Hardware Section of the Windows Update for possible updated drivers for the internal network card,
and of course all critical updates.

Thank you.
Actually, my ethernet card uses an NVIDIA nForce Networking Controller. Anyway, it is called like that. When I check it I see it is made by NVIDIA.
The mainboard as I can see it is a bit different from what it looks like in the manual. The model (number) seems to be the same. When I bought the computer there was at least one CD with NVIDIA software that wasn't for graphics. The system needed that software. Since then I've reformatted a few times, last time was last year, and I had some trouble in finding the correct drivers. I would not like to try to change the drivers, last time it was a hassle. Currently I have NVIDIA software installed for several things, for example memory controllers.
My computer needs at least some NVIDIA software (it asks for that after a new Windows installation), not only for the graphics card. I may have installed more NVIDIA software than I need, but I don't feel like playing around with it.
Perhaps my ethernet card can function without the NVIDIA software, but there is no problem if I try to connect the ethernet card by wire (directly) to my modem. That connection works fine.

About a 'hardwired' connection between the router and the ethernet card: it is not possible to connect the router to my ethernet card AND to have a working connection with the internet, since there is only one slot for that type of cable/wire (and wireless is by USB adapter). I had some problems with my previous router. Attempting to troubleshoot (same brand), when I connected it by wire/cable to the ethernet card the router became a mess.
I had no choice but to discard it. For the saga: http://www.wilderssecurity.com/showthread.php?t=246945
I really don't want to risk my router by connecting the LAN port to my ethernet card/computer. Sorry, that's one thing I don't want to risk.

Especially since at the moment I have no problems connecting to the internet, it's no longer sluggish, the speed is back to normal. Its firewall seems to be working. And when I access the router it has both the correct LAN and WAN information. But IPCONFIG /ALL gives the information as mentioned above, something I don't understand.

I hope you can work with these 'restrictions'.

OK good, the NVIDIA is in order.

It is possible that the router become an mess when you plugged the ethernet cable from the router into the computer network card because of the
Universal Plug and Play Device Host Service built into Windows (UPnP). Disable the following in Services they are not needed:

01)- Universal Plug and Play Device Host (UPnP) = the client of UPnP
02)- SSDP Discovery Service (SSDP) = the server for UPnP

As for IPCONFIG /ALL:

IP address 192.168.0.100 = the current IP Address of the computer assigned by the routers DHCP Server (dynamic host configuration protocol)
Subnet mask 255.255.255.0 = an method of splitting IP networks into an series of subgroups, 192.168.0.100 falls in the group 255.255.255.0
Default gateway: 192.168.0.1 = the IP address of the router, the router acts as an gateway between the computer/s in the network and the Internet
DHCP server 192.168.0.1 = the IP address of the router, the router is acting as the DHCP Server for the Local Area Network, (LAN)
DNS server 192.168.0.1 = the IP address of the router, the router is the gateway for the LAN, the router will fetch the Internet Providers DNS (domain name system or service)
Primary WINS server 192.168.0.1 = WRONG, you do not have an WINS Server connected to your network, this must be removed from the TCP/IP Properties WINS Tab
.....WINS = Windows Internet Naming Service, introduced with Microsoft Windows NT (new technology) to allow Microsoft File Sharing over the TCP/IP Protocol, and other stuff.

Within the routers pages displaying the Internet Service Providers IP information (ISP), the ISP Address, Default Gateway, and DNS Server will always be different than the ISP Address.

Example:
ISP Address = 82.111.111.111 - or whatever
ISP Default Gateway = 87.87.87.87 - or whatever
ISP DNS = 82.111.222.111 - or whatever

unlike the local router where all three are the same, the Routers IP, Default Gateway, and DNS Server are 192.168.0.1 (or whatever IP address manually assigned to that Router)

About the sluggishness with the Internet Connection:
Being that you are connected to the router wirelessly, it is possible that an neighboring computer is connecting to your wireless router or visa versa, the bandwidth becomes shorter,
hence an slower connection for both parties. Within the routers setup pages you will find an MAC Address Filter (Media Access Control). Enter the MAC Address of all the computers and
all the MAC Addresses of all the Network cards, including the wireless adapter to this list.
Any MAC Address not in the list, such as neighboring computers or wireless adapters, will not be able to access the routers connection to the Internet and conserve your bandwidth.
Also password protect the router to prevent neighboring computers access to the routers configuration pages. (192.168.0.1). Encrypt the wireless connection by utilizing either
WPA (Wi-Fi Protected Access) or WEP (Wired Equivalent Privacy). Now there is not much that you can do to prevent your computer from trying to connect to an neighboring router other than
telling Windows to block or ignore the connection within the network connections properties page when an new network is discovered.
Also allow the router to broadcast the SSID (service set identification). The SSID is the name of your wireless network.
All of this can be simplified by running the Microsoft Wireless Network Setup Wizard from Control Panel.

Recieved your PM and will investigate.

The UpNp and SSDP are disabled.
For as far as I know, these two were already disabled when I was still using my old router. Unless Avira (suite, trial version) disabled them.
Anything related to WINS in the properties tab is at automatic.

Fly,

You misunderstood the information in the Personal Message about replacing the network card in the computer. I never suggested that you replace the network card for troubleshooting purposes.
I am Posting this here Fly so that others will be aware of the possible compatibility issues involved.

You claim that you can connect the ethernet cable from the computer to the modem and it works - good
However, you also claim that if you connect the ethernet cable from the computer to the router it does not work - not good

Reason = by default, all ethernet cards should work with any connection if the manufacturer follows industry standards, in reality this does not happen.
You mention that the ethernet card in the computer is integrated, that might be the problem. The problem may be with driver incompatibility, or integrated to only work with certain devices.
You mention that the computer is custom built and not from any one manufacturer.....well, there you go.....who is the manufacturer of the integrated network card, and are updated drivers available?
Also, some routers, the ports need crossover cables instead of straight through cable connections, while still other routers can automatically sense the cable connection and reverse the crossover
connection to an straight through connection or visa versa depending on the manufacturer. By industry standard all ports should use straight through cable connections.....is your cable straight through
or crossover? Does your router support sensing crossover cable connections, or does your router require crossover cable connections, or straight through cable connections?
You also mentioned that you tinkered with the settings on the integrated network card, I do not know what you might have changed from the defaults.

It can be an mess sometimes troubleshooting networks of mixed manufactures. It can also be troublesome connecting different network cards from different manufacturers. By standard practice,
it is advisable to use network cards from the same manufacturer thought the network to avoid compatibility and connection issues. Even if the integrated network card worked with your router,
I would still suggest installing an ethernet card from the routers manufacturer for compatibility and throughput reasons. Also, whenever flashing the firmware of the router, the procedure should be
conducted over an hardwired connection to the router rather than an wireless connection for reliability.

Integrated ethernet cards are not hi-end network cards, and are mainly installed to provide instant Internet connection out of the box and reduce or avoid Windows Reactivation. An computer that exists
an ethernet card on the first Windows Product Activation is permitted more hardware changes than an computer that does not exist an ethernet card on the first Windows Product Activation before Windows
requires Reactivation. On the first Windows Product Activation, Windows will scan ten different hardware values that are used to create an hardware hash number. Using an complex algorithm,
the hardware hash number and the Product Identification Number on the Installation CD are combined to create an Installation ID for submission to Microsoft.....
.....of course this is an entirely different chapter.....

Partial quotes above.

The manufacturer of the network card ? I MAY have that information somewhere, but I can't seem to find it. I'd have to spend more time looking for that information.
However, the network card uses NVIDIA software, as mentioned in the PM I sent you. It is a large file, and supports a number of devices, not just the graphics or network card. This particular NVIDIA file (saved on desktop) didn't come with my computer, but when I needed to reformat last year I needed NVIDIA software, and for some reason I installed this particular software. I remember downloading different NVIDIA software before that, but at that time this was the only suitable software I could find. It was later/newer NVDIA software. Immediately after my last reformat last year I started using an imaging setup, and I don't have any earlier NVIDIA software at hand. Anyway, I'm paranoid about connecting my computer to a LAN port of my router, because of what that did to my older and now discarded router.
'If it ain't broken, don't fix it' It seems that my router is not functioning as it should, but that's better that a non-functioning router.

I don't know anything about crossover cables or straight through cable connections. I spent a few minutes trying to figure it out, but it's not clear.
I don't know what my router supports, but in the PM I sent you I mentioned the router model. It SEEMS that the long cable/wire which I can use for a direct wired connection between my computer and my modem is similar to the cables that came with my router, they both fit in the slot of my ethernet card, router and modem.

'You also mentioned that you tinkered with the settings on the integrated network card, I do not know what you might have changed from the defaults'

Tinkered with the settings of the network card ? I'm not sure what you mean. I have installed NVIDIA software for it (as mentioned above), that particular file installs NVIDIA software for a number of devices.
While I may have 'tinkered with the settings' trying to troubleshoot my older and now discarded router, my current image uses the NVIDIA software as it was when I first installed it.

I'm not sure why I should purchase a new ethernet card from Sitecom, it costs money and I'd have to guess which ethernet card to purchase. My current router came with a USB adapter in the same box.

Btw, this computer is about 5 years old.

Fly,
Install this network card with the driver that is included and your problems are solved.
You can then disable the wireless features of the router and have no more interference from neighboring computers.
There is no connection more reliable and faster than an hardwired connection.
Small price to pay for security, reliability, and speed.

Thank you, I may do that. It's not expensive.

But I suppose that's for troubleshooting of my router's unusual behaviour ?
Because, other than that, I wouldn't need it. I use a wireless connection for convenience, to avoid the inconvenience and the messy look of a cable passing through several rooms in my house.

[Fly]

Btw, is that incorrect WINS server a security problem ?

Communication between my router and my adapter is encrypted (I know because each time I activate the computer I have to enter the passphrase in the firmware of my USB adapter (copy and paste), that must be an error in the adapter or its firmware) and I have have a non-default password.

My guess is that noone can bypass that protection ?

No, that incorrect WINS Server is not an security problem, especially in your case, as you do not have an WINS Server.
Any entry in the WINS Tab, in your case, could cause communication problems and must be removed.
Your WINS Tab should look like this:

211595

Ignore the: Enable LMHOSTS lookup, the default is: enabled, and leave it alone, it is irrelevant to our discussion.


There is no error or problem with the wireless adapter or firmware, it simply is not setup correctly.
It is good that you have an non-default password for the router.
Also, the four 10/100 Mbps Fast Switch Ports on the back of the router are (Auto-Crossover). you are OK here, the cables you have are Straight Through Cables.


According to the SitecomWL312.pdf manual, WPS (Wi-Fi Protected Setup) is the simplest and most secure way to establish an connection between the wireless clients and the wireless router.
You don’t have to select the encryption mode and fill in an long encryption passphrase every time when you try to setup an wireless connection. You only need to press an button on
both wireless client and wireless router, and WPS will do the rest for you. Instructions for WPS setup can be found on Page 31 of the Manual:
http://www.sitecom.com/showdownload.php?id=3779


There are two ways to place the Sitecom Wireless Router in WPS Mode:
01)- On the rear of the router, press the reset button for two seconds. (page 07)
02)- Or click the WPS Push Button: "Start to Process Button" in the web configuration interface of the router. (page 31)

To establish an connection from the Sitecom Wireless USB Network Adapter to the Sitecom WPS protected router:
01)- Simply press the button on the Wireless USB Adapter (page 31 and Web)
http://www.sitecom.com/showdownload.php?id=3719&hasacr=1

02)- Or simply click the button in the utility of the wireless USB Network Adapter. (page 31)

This is very secure, because the passphrase key that is randomly generated by the wireless router during the WPS process, rejects connections from devices that are not WPS compliant. (page 32)
When setup properly, I can see that this router can be very secure. First, the routers WPS automatically sets up WPS with an random passphrase, any devices that are not WPS compliant can not
access the router. Second, populating the Wireless Access Control List with all the MAC Addresses in your Network will prevent any MAC Addresses excluded, access to the router. (page 30) Third,
password protecting the router with an non-default password will prevent any changes to the routers configuration, internally and externally.

WINS Server is still at 192.168.0.1
I've tried a couple of resets and made a few attempts to get this fixed, with no success.

It used to be different. IPCONFIG /ALL doesn't give any 82.X address.

Also, when I check <start execute> after each reboot it states 'cmd' instead of '%temp%'. I can enter '%temp%', but after a reboot it always changes to 'cmd'.

I don't want to spend a lot of time troubleshooting this. Maybe it's my punishment for buying a cheap router. :ouch:
Any suggestions are welcome.

Is your modem set to bridge mode?
When connecting modems and routers the first device, the modem, has to be in bridge mode, usually.

I have no idea. Is there an easy way to tell ?

For as far as I know, accessing the modem once set up is not possible. I can use it (no problem when I connect my computer to the modem by wire), but that's all. There is some kind of reset button, but it doesn't work.

Troubleshooting to access the modem's menu would probably take several hours, and with the same result as previously.

Lets bypass this router and connect your wired device directly to the cable modem or dsl modem. Can you connect to the internet?

Now you it's the router configuration or there is a problem with the router brand your using. Try a different brand if you can. Or have that router your using serviced if you just got it and it's still covered under warranty.

I'm not sure if I have a (valid) warranty, I'll have to check that. It certainly was a budget router.

I think a great deal of this problem is caused by my ISP. Not sure how.

The IPCONFIG /ALL gives unusual information. Maybe the setup is incorrect from a technical perspective. When I log in to the router I can see it has the correct LAN and WAN information, for as far as I can tell. It seems to work fine, though. For the time being ...

Then did you install the router with the CD software that comes it? If not try that. Other than that, manual settings in the router might work or not. Just might have a bad router if you have tried everything else.

I believe that the router and modem are setup correctly and there are no problems.
There is only innocent confusion on your part about the echo information displayed for IPCONFIG /ALL.

IPCONFIG /ALL will echo 192.xxx.xxx.xxx when the topology is:
Direct wired or wireless connection from the computer to the router.
The router is the DHCP Server, and will assign the computer an 192.xxx.xxx.xxx IP Address that is in turn echoed by IPCONFIG /ALL or,
The computer is assigned an static IP Address outside the DHCP range of the router that is in turn echoed by IPCONFIG /ALL.
The router is acting as the Edge Gateway between the computer and the Internet. The router will communicate with the computer using 192.xxx.xxx.xxx addresses, these addresses are not
routable on the Internet. The router will communicate with the Internet using the Internet Service Providers client IP Address 82.xxx.xxx.xxx that is routable on the Internet.
The router retains the Internet Service Providers client IP Address from the modem and is not echoed in IPCONFIG /ALL because the router shields the computer from the Internet, meaning,
the outside world beyond the router only sees 82.xxx.xxx.xxx and not 192.xxx.xxx.xxx and the inside world, the routers network, only sees 192.xxx.xxx.xxx, and is echoed by IPCONFIG /ALL.

IPCONFIG /ALL will echo 82.xxx.xxx.xxx when the topology is:
Direct wired connection from the computer to the modem.
The Internet Service Provider is the DHCP Server, in turn assigning one modem the Internet Service Providers assigned client IP Address, 82.xxx.xxx.xxx, the modem retains this information and
is echoed by IPCONFIG /ALL. The assigned client IP Address and the Internet Service Providers Default Gateway and DNS Servers will not be the same.
The modem is the Edge Device and the assigned client IP Address 82.xxx.xxx.xxx is routable and visible on the Internet, and is echoed by IPCONFIG /ALL.


As for the WINS entry reappearing, I can only think of one way this might happen, the routers DHCP Server configuration exists an WINS entry.....if so, remove it.....if it is there by default,
you will have to remove it every time you reset the router.

Also, let us check the LMHOSTS file, type: nbtstat -c at the Command Prompt and Post an Screen Shot

As for the hardwired connection from the computer to the router not working, other than an bad port on the router or an bad ethernet cable, I gave you the reason and solution in previous Posts.

[Fly]

I remember seeing the 82.X IP in IPCONFIG /ALL in the past, when I was using a router. ??

The nbtstat -c gives some information, but it's not in English. IP address of node (?) : [192.168.0.100] Scope ID : []
No names in cache (something like that). That's all.
I can't change the WINS to a '0' number, the software won't accept it.
It seems I can't change the WINS in the router.

[tipstir]

WINS doesn't need to be enabled here. Router should automatically detect the ISP DNS and connect network nodes (devices by DHCP) to the internet. To much time is spent on this router it's not working correctly. The only options are to re-flash the firmware with a newer one or return it back to where you got it from.

[HKEY1952]

I agree with Tipstir.....
-{ Quote: "The only options are to re-flash the firmware with a newer one or return it back to where you got it from" }-

Before you can re-flash the firmware in the router, first an reliable hardwired connection from the computer to the router must be established.
Re-flashing the firmware of the router through an wireless connection may not work and is not reliable because when the router reboots the connection
must be there or the procedure may have adverse affects.

It is good that nbtstat -c echoed "No names in cache" that is what I was looking for.....the LMHOSTS is clean.


-{ Quote: "I can't change the WINS to a '0' number, the software won't accept it.

Now you know the source of the problem.....corrupted firmware.....or defective router.....
This would also explain why an hardwired connection from the computer to the router can not be established.....the routers firmware does not see the connection, or,
one or more Ports in the router are defective.

Well common sense would tell anyone to connect using a wired connection. Though I see you like to use those other commands like nbstat an etc.. But The router needs to be functional. To bad the OP won't tell us which model of router it is? If ports are bad they're DUFF is the term.

I've posted this on DSL Reports about flushing out the NVRAM in the Router.

This is certainly a router problem and not an isp problem. If the latter were the case, you would have network issues even when connected directly to the modem. Don't lose sight of the fact, as you mentioned in post #1, there were no problems for several weeks. Routers do fail; my D-Link DIR655 failed after < 1 year. Good thing it was still under warranty :)

An tip for tipstir:

nbstat is not an valid, recognized internal or external command.....however.....
nbtstat, the command-line tool, has nothing to do with the router.....directly.....

nbtstat is an command-line tool used for displaying NetBIOS over TCP/IP (NetBT) protocol statistics.....
nbtstat allows an refresh of the NetBIOS name cache and the names registered with Windows Internet Name Service (WINS).....

At the Command Prompt type: nbtstat -then press Enter for an list of Command Line Switches.

Thanks all. I'll have to make up my mind.

I'm not sure, but it could be that the issues as mentioned in this thread started when I plugged the cable of my modem in the LAN port of my router. Perhaps, but I do not remember, the problem was caused by connecting the LAN port of my router to my internal ethernet card which uses NVIDIA software.

It was a 'cheap' router, 50 or 60 euros including the USB adapter ! And the router looks cheap and ugly on the outside (mostly cheap white plastic, made in China). I paid a lot more for my previous router.

'There most certainly is an security breach.....the networks edge exists an faulty router.....'

Maybe. But the wireless traffic is WPA-PSK encrypted, non-default password, and when I deactivate my software firewall the router's firewall seems to work well. ?

The typographical error is not the issue.

The issue is, you stampeded into this Thread and started Posting what exists as legendary advice, in your mind only of course, without first knowing the facts.
Your advice to me was that the command nbtstat will not work until the router is working first, and you are completely wrong.
The command nbtstat has nothing to do with the router directly. I believe you only made that statement because you assumed that we were trying
to enable WINS, where as in reality, you know, outside of your mind, we were in fact trying to disable WINS, and trying to find the source that was
automatically enabling WINS.....and we did find the source, the routers DHCP Server WINS entry. The router is faulty because the WINS entry in the router
can not be removed. The only sound advice that you did give was to try re-flashing the routers firmware or return the router.....of which I agreed, and agree.
It helps to read the entire Thread first before Posting erratically.

Troubleshooting takes time, especially when conducted over the Telephone or Internet, the client must be your eyes and source of information.
There is no such thing as spending too much time troubleshooting when trying to salvage something that is really wanted or when limited funds exist for the client.
Without basic training and educational studies, the average person does not have the know how to troubleshoot and perform computer repairs or upgrade electronics and
should not be degraded as not having common sense. The Original Poster did in fact send me an Personal Message containing the Router Model Number and other pertinent information.
The router is an Sitecom Router.....if you read the Thread.....

Repeating the same info over and over again can be made easy if you post what you know to one page and direct the user to that site. Thus that's what I do.

Don't get so worked up into this debate you have your no it all and I have mine. You share and I share info. That's how the internet is. Not a place to not share the knowledge.

You are able to surf with your connection to the modem, and then add in the router and get no access or very limited access.
This means devices are not configured properly or a problem with the router.

Just like you access your router you can access your modem.
With the computer connected directly to the modem can you get the modem access page?
192.168.1.1 or similar.
Locate your setup and/or connection page. Should be something called "PPPoe" for DSL.
It is the PPPoe you are going to change to bridge mode.
After applying changes you will lose internet connection.
Connect the router, access the setup page and set to accept PPPoe and add your username and password for the main ISP account. You will also need your ISP's DNS servers.

If the modem is supplied by the ISP, then give their tech support a call, telling them you want to add a router to the modem. Let them walk you through the process, take notes.

You must rule out user configuration error before you say the router is bad.

I'm not sure I understand what you are trying to say.

I can get a direct wired and working connection between my computer and modem. No problem, for as far as I can tell.

I can't get access to the 'modem page'. Well, MAYBE I could if I were to disconnect my modem from the internet. Otherwise, it doesn't work for sure.
But I don't like to fiddle/mess with those cables/wires, I truly know the meaning of 'if it ain't broken, don't fix it'. (I can't just unplug that cable/wire)Anyway, even if I could it almost certainly wouldn't help.

Broadband connection: cable, not DSL.

I actually can access the internet through this router. But the topology seems to be wrong. (see WINS server) Btw, under IPCONFIG /ALL I get a 10 year lease ! The router's firewall seems to work. I'm not sure to what extent that WINS issue matters.

Well, don't tell me that my ISP isn't the source of the problem.
Years ago I didn't use a router. Then, my ISP changed the modem and my wired connection no longer worked ! (Something about the distance between socket and modem or computer, I don't recall) The cable connecting my computer to my modem was nicely hidden. I wasn't very knowledgable at the time and went for the quick fix, installing a router. The holes in the walls etc. have been filled since, and I don't like to have a long cable, out in the open, through several rooms, even aside from the fact that a router provides additional protection.

My original ISP has merged with others. They sell Sitecom routers to their customers, but with their own software preinstalled. I don't trust them with that. They even manage to put a Flash cookie on my computer when I access their website, while the Flash player has been configured to block Flash cookies, settings as tight as possible. I call that hacking. It's a debt ridden company, bad service, I'm not the only customer who has (router) issues with them.

As I'm writing this I'm experiencing connection problems (frequent loss of connection, started today or yesterday) which I also had with my previous router. Same type of problem, according to the eventvwr.

I'm considering a change of ISP, especially if I can get a router or wireless modem for free.
