    Many thanks for the links. Some are just what I have needed. Seems I have a "wanna be" war driver in the area tapping on my WPA protected network. He has`t gotten in but has been causing a problem with IP conflicts. Seems on or two of these articles may provide the cure. :thumb:

    Glad to help. All I did was post a post!

    Let us know what you do to lock out this "war driver".

    Have you got your own hardware firewall/router? They are hard to break into, if you set a strong pasword for the router!

    Glad he can't crack through, but they are out there!

    Very good research Escalader.
    With all these related links in one place, I'll refer to this thread in the future.
    Thank you.

    This is my current set up. copy and pasted from another board where I participate as well.
    Currently running a 3 PC (2 wired, 1 wireless) in home network. Sense this concerns "only" the wireless client I will stick to just that info. unless more is needed\requested. The wireless laptop uses a Linksys Wireless-G with WPA-TKIP enabled with a 63 mixed character key. This connects through a Linksys Wireless-G Access Point. With both their user names changed and a non-dictionary password. The AP is wired to a Linksys EtherFast 10/100 8 port switch with the 2 other wired clients. The switch is then hardwired to a Linksys-G Bridge. The bridge then sends and receives it`s connection via a Maxrad directional antenna over about 150'. At the reciving end is an identical Maxrad directional antenna, Linksys AP, then a 5 port Linksys switch with one cat5 going to the cable modem the others running to another Linksys 16 port switch then are run to the other PC`s (1 wireless as well) and printers on the network. This second group of PCs` is not experiencing the same problem. All IP`s are static. My 3 PC`s and the AP have DHCP disabled. On occasion I will receive the Windows warning on all 3 PCs` of an IP conflict on the network. At which time of course I lose connectivity to the "other side of the WAN (shared drives) as well as my Internet connection. This only happens on my 3 clients, not on the other side of the WAN. While trying to run down the problem I discovered an unsecured network\PC in the area operating on the same channel broadcasting its MAC address.However the signal strength showed as 0. No strange PCs showed up in My Networkplaces either. The problem can be eliminated by shutting down the AP and falling back on the wired NIC on my laptop. wwhhhhhheeeeewwww....... Hope that is enough info. Now for the question. Can this 0 signal strength unsecured network be the cause of the IP conflict on our secured network? Thanks for any and all input\info.\suggestions.
    Added;The foreign PC has disappeared and so has the IP conflict problem. Coincidence?


    Also running ZA Pro on the two wired and Comodo on the lap top.

    Sorry, way over my job level!
    Hopefully, other members here will help with this question.
    I'm glad the stranger has disappeared but he may only be out shopping.

    On signal stength you want enough to reach your client PC's but no more.
    The other point was to set it at a different frequency than you neighbours so as to avoid interference. As the further you broadcast the better for the baddies. With the long complex code you have I would think they can never break it in our lifetime.

    Your cyber prowler may be attaracted by all the gear and big set up... I gather I could see it if I were to walk past you site(s)?

    I also use ZA pro. It has a lot of power...

    LOL He still shows up every once in a while. Really not sure of malicious intent. They have MAC enabled and as normal is broadcasting their SSID. But for the last couple of days there have been no IP conflicts. He\she may not even be aware they are broadcasting.

    Our signal strength is a bit "over kill". This was our first endeavor into the world of "longer range" wireless. Considering the distance, the fact we are shooting through several trees, and that we wanted reliability in all weather conditions is the reason for the set-up. We achieved all our goals. But with a slight security trade off it would seem. On the advice from the Company we purchased the external antennas from, we actually down graded our original set-up to these smaller, shorter range antennas.

    Actually, the only visible equipment are the 2 Maxrad external antennas. They are less then a foot square and set just above single story roof level. Many people do not even notice them, even when walking right past\under them when coming to the house. I think only those who know about Wi-Fi would even know what they are. The only real give away is our signal\strength. You would have to be looking for it to find it.

    Have looked into the logs ZA and saw no intrusion attempts. I am still learning Comodo as time permits. Though I have not received any pop-up warnings of unwanted incoming traffic.

    your first post link scared me a bit. i use WEP128bit encryption is this secure? because the first link says WEP isn't secure. but as far as i know WEP is the only encryption my Nintendo DS supports. but I would still like to know if its safe enough

    WEP is more secure then using nothing. However, it has been and is crackable.

    Don't be scared, do the research on the links provided that impact your setup.

    Check out the password thread underway on this forum.

    Passwords must be 15 characters or better in windows XP, as I understand it you need to move to WAP away from WEP.

    Hide behind a hardware router and software firewall of your choice.

    That's the best I can do for you based on my limited knowledge.

    To be clear, I think Escalader meant to say: WPA (WiFi Protected Access) (preferably WPA2), which is the secure wireless communication standard.
    WAP (Wireless Access Point) is the hardware that creates an area that wireless devices can connect to the network.

    With all these acronyms, one letter change can have a totally new meaning! :D

    Yes, D that is what I meant. Thanks for the editting job!

    The devil is in the detail isn't it!

    I hate wireless, still haven't recovered from my bad experience with it, probably never will.

    I will leave the wirless advice to you, it's easier that way.

    Have a good turkey day if you celebrate that sort of holiday...:D

    Just a word of saying, try to stay out of wireless,

    because once you stepped into it deep enough,

    you won't able to pull yourself back,

    it's the swarm the will suck both you and your money in,

    and there is nothing call "safe" in this world

    unless you only keep "that" in your heart or mind

    for now.

    If you have a device with only WEP, but it has a standard wired ethernet port, you can always get a wireless ethernet adapter (a wireless unit that plugs into the ethernet port and then connects to your router/access point). Some access points will switch modes to do this, but you can often find these in the gaming network devices of your local electronics store.
