Thanks for your reply, I got a new laptop again this year and similar issue happening again, so far I got no luck since I didn't have password for my ATT router (yet)
You have valid argument in here, since I noticed in my Dell wireless manager how the card keep jumping around from one frequency to another.
I am planning to call ATT to get my router password when I am back from vacation and try your trick again, thanks !
