Believe it or not, what fixed my problem is downloading another Acer laptop's model's wireless driver from Acer. I have a second Acer laptop (different model than mine). I noticed it's using the same AR5007EG Atheros wireless adapter as mine but with a different year and driver version number. And it was having no problem surfing. So I downloaded that model's driver from Acer and used it on mine (after uninstalling my adapter completely) and now I can surf. What's funny is that I tried downloading MY acer's wireless driver from Acer and it didn't work. It was the same version I had before. FRUSTRATING on Acer's part!! who would've thought you had to dig the idea up of downloading another laptop's model's wireless driver??? But anyway that's what did it for me. Good luck.
