My internet drops thus I perform usual and try to unplug both my wireless router and modem as that generally repairs problem. But after several tries of that my PC that connects wirelessly to router was unexpectedly enable to locate any routers at all. When I go to "view networks" it says it's "not connected." I know it is not a signal problem, it always shows about 100% signal strength. When I open up the wireless wizard, it shows no routers on the list, which is strange because it generally locates around 4. I am still able to connect to internet with router that it is supposed to be connecting to with this laptop that is directly connected to wireless router that the other PC should have found. So I am thinking it is something with PC.
