Hi, First, I suggest that you upgrade the NIC driver and try to check the problem in Clean Boot: http://support.microsoft.com/kb/929135 Note: Clean Boot is a step of troubleshooting, we can go back to normal by running MSCONIFG. Also this problem may be caused by SNP feature, you could disable RSS and TCP Offload manually: netsh int tcp set global chimney=disabled netsh int tcp set global rss=disabled netsh int ip set global taskoffload=disabled If you have further question about this issue, please feel free and let know.

I have two computers on a wireless network: a desktop and a laptop. The laptop works fine and I am using it only as a comparison. The laptop is an older laptop and is only capable of connecting using 802.11b running windows xp. The computers network card is capable of both 802.11b and g it runs windows 7. Both computers were running fine until a month ago when the desktop started acting up. Also both computers are running Avast internet security. Running the command: ping -t -w 1000 www.google.com from the two computers generates very different results. The laptop shows no lost packets. However the desktop will go anywhere from 10 minutes to a couple hours fine, but then it will have large timeouts followed by some general failures (during the same time period the laptop shows no networking issues). Or it will occasionally have a line or two stating general failure. The previous card at one point had an error saying something like not enough resources (i'm sorry I can't remember the exact error message as I only saw it once). The subnet mask, gateway, and dns servers are identical between the two. They have different IP addresses. Because of this I was convienced the network card had gone bad and so went and replaced it. This had no effect. Any ideas/solutions? I am completely baffled.

I'm having similar problems on a new Windows 7 laptop. I have 3 other wireless laptops running XP and never experience these problems. On the Win7 machine, I get errors reading and writing files to my server, errors printing, etc. An example when printing a 40mb graphic, the job starts to send to the printer but hangs and ends up erroring out. I'm certain it is some setting in Win7. I can open the same file on my XP machine and print without issue. I tried the netsh commands above and received an error that they must be run as Administrator. I'm the only user on this machine - and thought I was an Administrator? Suggestions?
