Solved Wifi suddenly doesn't show available network connections

My fully updated Windows 8.1 notebook suddenly will not show any wifi connections when I click on the icon in the system tray (it shows "No Connections are Available", although it is connected, and I can surf and browse normally).

To connect to a new network, I have to manually enter the details of the network, and then it connects. This is something new, since previously it would show all the available networks, and allow me to make a selection (which is normal). What setting could have flipped do enable the above situation?

Thanks

Hi,

I have faced once situation when one of the wifi network (ssid) disappeared from the available networks. Manual reinstalation of wifi nic drivers helped. I had to use drivers directly from laptop's vendor. Those from windows update didn't work properly.

Thanks, a complete uninstall and reinstall of the wifi driver did the job.
