heres what i can tell you to try, because i know what your talking about. Go to your notification area by either hitting windws+d to go to your desktop and shift tab twice until you hear Notification Chevron  button, then hit left arrow until you hear something like hibdon
Internet access  button (replace hibdon with your own Wi-Fi netowkr name). then, hit enter. You should hear this Network Connections  window. List. hibdon Connected, secured Signal 4 out of four bars   1 of 11 (replacing the hibdon with your own connected network name or top list of the networks available) then if you need to connect, hit enter on a network and type in the password if needed. You might have to hit tab twice to get to the connect button after you press enter on the Wi-Fi name. If that button says a wi-fi name but no internet access, it is a router problem. If it says no networks available, then your wi-fi is disabled completely, in wich case your best bet is to try restarting your PC (without choosing any of the settings you mentioned) and if that doesn't fix it, look at that link posted in post number two. That is all of the help i cna give without more information, such as your computer moddle or creator, sense they sometime shave specific different wi-fi settings, especially if it comes to you using a not-built-in or manufactorer made wirelesss card.

tank you all
