Homegroup Network Connectivity

I have a Homegroup/Network using a late PC Windows 7 Home Premium 64bit with a lan connection to an Aximcom MR-102N Router connected by USB 2.0 to a Telstra MAXON BP3-EXT modem for NextG internet; Laptop A Windows 7 Home Premium 64bit connected by wireless and Laptop B Windows 7 Ultimate 32bit connected by wireless. The printer etc are connected to the PC. My PC communicates perfectly with both laptops and visa versa and the printers are available and work with all three. The problem is nthe neither laptop is able to communicate. I have attached some trouble shooting details which are self explanatory. I am using the 'Interactive' mode on my personal ESET Smart Security 6 Firewall. At no time has either laptop or the PC for that matter given me any indication that intercontact has occurred. Having to manually add rules and profiles etc. is a daunting task for someone of my inexperience, eg, hoew do I obtain the IP addresses and protocols etc & etc.
Can anyone supply some assistance or answer to this problem.

Thanks for your help RexG

 

Have you gone through the ESET KB Article below?

Slow or no Internet/network/printer connection: Solution checklist

Each step includes links to articles that will show you the step-by-step process including screenshots. You stated in your post that this may be too daunting a task for you to attempt alone. If this is the case, we do offer customer care services and our agents would be glad to walk you through the steps, if that might help. You can contact us online or by phone.

 

Thanks dwomack for your quick response, I will follow the instructions given as time permits, I have glanced at the knowledge base articles and think it could help.

Cheers RexG

 

Hi dwomack,

I have just done what was said in the Knowledge Base, ie, added the laptop ip's to each other and opened port 445 on both laptops, but am still where I sytarted, ie nowhere. I did manage to find out how to get the ip addresses however. Have you any more suggestions, please?

Thanks Heaps,
RexG

 

Make sure that you have the following options enabled in the IDS setup:
1, Multicast address resolution (LLMNR) in the Trusted zone
2, Windows 7 HomeGroup support

Also make sure the other computer is in the Trusted zone.

 

Thanks Marcos for that info. I will look into it abd see what happens.

Cheers RexG

 

Thanks for the info marcos, both laptops were in the trusted zone and both were enabled with respect to Windows Homegroup support, the other box regarding (LLMNR) was unchecked and I have now enabled it on both, however I am still in the same position I was in before I tried anything. Have you or anyone else got any other thoughts on the matter, please.

Many Thanks, RexG

 

Whenever a certain communication is blocked, please do the following:
- in the IDS setup, enable logging of blocked communication
- reproduce the issue
- check the firewall log for detailed information about the reason for the block (Copy & paste the recent records here which will give us a clue.)

 

Thanks Marcos for your quick reply. I saw those boxes unchecked so I will enable and see what happens. It will probably be a couple of days before I can get back to you.

Thanks Heaps, RexG

 

Hi Marcos,

For your info Laptop A's iPv4 Address is 192.168.1.27 and Laptop B's address is 192.168.1.25,
This is the log from Laptop A after I tried to open its tree in Windows Explorer on Laptop B:-

Hope you can find something here,

Thanks RexG

 

It seems that only UPnP is blocked. Does allowing "UPnP for system services in the Trusted zone" in the IDS setup make a difference? If not, post here the current firewall log records from the point when the issue occurs even with the mentioned option enabled.

 

Hi Marcos,

Did that and no difference, the two setsof logs are below:-

I had the same problem RexG.

The solution was to open "Advanced setup - Network - Personal firewall - Rules and zones", click the "Setup..." button for "Trusted zones" and change the protection mode from the default "Public network" to "Home/work network".
