Scott:

I recently bought a WPC100 wireless adapter for my wife’s gateway computer and installed the associated software.

Hardware: Gateway laptop 400VTX
Router: WRT54G v3.1
Wireless Adapter: WPC100
Wireless Security: WPA2
Operating System: Windows XP SP3

However, when I resume from standby mode I find that the computer refuses to communicate with the router. I tried to ping the router but there is no response. The only solution I have found is to reboot the machine. I have found that if the laptop has been in standby for a short period of time then it reconnects without a problem. I also have a desktop computer I recently built with Windows XP SP3 that also connects wirelessly to the same router (also using WPA2 and a WMP54G adapter) and it does not have this problem. Do you know what could be causing this problem? A web search has turned up users with similar problems but no indication of a solution.

Thanks.

I looked at the driver *.inf file, which indicates that it is from PCI vendor ID 168C http://www.pcidatabase.com/vendor_details.php?id=174 (Atheros), and is device ID 0023, which further searching showed to be an "Atheros AR5008 Wireless Network Adapter".

Searching on the Vendor/Device string (PCI\VEN_168C&DEV_0023) is a good way to find newer drivers from alternative sources: http://www.google.com/search?hl=en&q=%2 ... EV_0023%22

Scott:

It turned out that your first suggestion was the key - having Windows manage the wireless connection instead of using the Linkysys software. I haven't updated the driver yet because I wanted to try one thing at a time to see which one fixed the problem.

Thanks a lot for the help.

Thanks for letting me know what worked! Scott.
