i have an hp compaq presarion f761us
im running vista premium and in the process of trying to turn off the visuals, i think i did something i didnt really want to do. idk what i did, but my wireless antenna wont turn on now, the only way im connected is because im connected directly to my modem. can anyone tell me what i did? or if theres a way to reset everytjing to the way it was so i can atleast have wireless again?

Did you try using System Restore to roll your settings back to a later date?

if you already tried the keboard combination or manual wireless switch, check in Vista to make sure the wireless card is simply not 'disabled', if you see a red X, you can click on it to Enable it. I had this happen to one of my users before.

Also check the bios for wireless adapter enabled!
