regularly losing connection to workgroup W7

hello - my computer is a dell laptop Vostro13 with preloaded W7 32 bit. I regularly lose my connection to the workgroup while all 4 other computers do not. i have shortcuts direct to various machines that fail. i can sometimes restart the network by going into the my network places section and it can then connect to the other workgroup computers but sometimes a full reboot is required. this happens sometimes multiple times in a day - any advice? i have turned off the power save settings that shut down wifi, i am using built-in wifi connection like the other machines on my workgroup are. thanks.

Hello,

Click Start>Run. Type in 'ipconfig /all' and post the results in here.

What type of router/wireless access point are you using?

Does the connection drop off when you do a certain thing? For example connect another PC to the wireless?

TRENDnet TEW-651BR Wireless N 150 router

>Does the connection drop off when you do a certain thing? For example connect another PC to the wireless?

not your example, no. i can't think of anything that would cause me to lose connection with the other LAN users in the workgroup, i do not lose connection to the internet for example.

details below - please advise - thanks!

The Router (192.168.10.1) is giving out two DNS Addresses via DHCP, one internal and one external. Remove the external DNS Server (156.154.70.1) from the DHCP settings on the router and try agian. Leave the 192.168.10.1 address as a DNS Server.

Hope that makes sense.

hi dave

thanks for the help but the router is not the culprit. when i was in china i did a dns speed test from google which told me the fastest DNS server to use and i modified my config to that setting. now i have manually set the DNS to 8.8.8.8 (google) for inside USA. do you really think having modified the DNS server on my wifi properties could be related to me losing my connection to the workgroup LAN members shares? thanks.

Hi Brad,

You can leave the DNS Server on the router pointing to 156.154.70.1 if you wish but it does not want to be in as the primary DNS Server for your PCs. This is because it will use that server to do local lookups as well. Remove that address from your DHCP settings only.

hi dave
perhaps i was not clear in my previous response. there is no 156.?? number in my router at all. that number was entered in the wifi properties for IPv4 by me when i was in china for speed reasons, i have removed the setting for now and the DNS now reflects the router number, yet the problem persists. thanks

Ahhh ok, sorry Brad.

Can you right click Computer and select manage. In Computer Management there will be a link on the left for Device manager. In Device manager right click your network adaptor and click Update Driver Software.

the wizard reports driver is current one.

FYI i run 3 LAN's in 3 countries, all of which are called workgroup - this one is the only one that has this issue of forgetting the other workgroup members and their shares.

it could be an issue with the router, i have a habit of buying the cheapest router - but this may be in error. could the router have some stupid power save feature causing this issue? no idea.

thanks

Hi Brad,

Is file and printer sharing enabled on the other PC's on the network?

You said that "this one is the only one that has this issue of forgetting the other workgroup members and their shares." - Are you saying that you can see other shares that aren't there?
