Running Win7 Home on Acer 5749Z and windows seems to think it's the router, where the problem is. I disagree, since running 2 other computers from the router, one Win7 laptop and the other is an Acer 4720Z WinXP. The both show very strong signals.
Tried recovery, update driver, resetting router. All to no available.
Have USB Wireless adapter and connection is slower but strong.
Do you know how to determine if it the card or the antennae that is the culprit for dropping wireless connection?
