I'm running Windows 7 on my Asus laptop with the Intel 5100 AGN card. Being that it's a laptop, it gets moved around a lot and connects to several networks. When I get to a new location, I resume from standby and it automatically connects to the wireless network. However, sometimes I will only have Internet access for a few minutes before it suddenly and mysteriously stops working. Any active connects will remain active (VPN, etc) and functional, but I cannot make new connections. Rarely, if I just wait I'll be able to use the Inernet after ten minutes or so, but only for a short period before it disconnects again without notice. A restart will fix the issue, and it doesn't seem to reappear unless I make mess with the network (like turning the wireless off and plugging the wired in) or if I enter standby. Doesn't occur every time though. The whole time this is happening I can still access local network locations like the router's web-interface, and local machines connected to the same network. This also occurs with my wired connection, apparently, because it just now stopped working. I've disabled the "let windows turn this device off to save power" option on both network adapters. No problems getting an IP address, but cannot surf. Doing ipconfig /release and ipconfig /renew does not help either. Happens with the latest Intel Vista drivers and the Windows 7 drivers from Windows Update. The "proxy" option in the internet options doesn't fix it either. Any suggestions?
