This is weird, but if my Win 7 computer is on and connected to the router (wired), then neither my Toshiba laptop (also running Win 7) nor an iPod will reconnect after sleep.
After reading through this forum
, I tried disabling the Homegroup on both Win 7 computers, but it didn't help. Even tried disabling the IPv6 on the network adapters.
I've also made sure power remains on to the wireless adapter even when computer is asleep. And updated all my drivers
The only thing that helps is turning off the wired Win 7 computer. Obviously not a permanent solution!
The laptop is also showing a Microsoft Virtual WiFi Miniport Adapter #3. Could this have anything to do with the problem?
