Having had a field day trying to find a solution to this problem, I have resorted to spending 10 bucks on a wifi usb dongle. Bingo...WIFI shows in list amongst all the others.
I have a realtek RTL8188CU on my motherboard with a driver I can't remove. I.e. I dont get the option to remove the driver when de-installing the wifi in device manager. Therefore the restart always used the same old driver that is somehwere in the system.
Since I didnt feel doing a clean Windows restart, which some suggest and is a massive shortcoming with Windows, I ordered a USB wifi dongle. Surprise surprise, the netwotk finally shows. So spend 10 bucks and stop waisting time. This seems to be the only way getting around that old driver.
I've plugged in the new dongle, but still nothing showed other than the neighbours networks. I had to disable the old wifi adapter first. Go to network adapters and find two and not one adapter once youve inserted the new dongle. Then disable the old. Make sure before you plug in the new you now what the old adapters name is so you select the correct one disabling it.
