I have wireless net and one day while I was on it just stopped working. So I checked the thing that sends the signal and restarted it and all, I also refeshed the thing that receives the signal. When I go to connect to my net it says it has a signal but it wont connect to it...says its just unabled to and theres no way to diagnose it. I think somethings blocking it, I tried putting down my firewalls and restarting to see if it was my anti-virus but still same thing. My next door neighbors net works( they leech off mine) so it has to be my PC. Any help before im on hold for 5 hours with my net provider?
