I have a Toshiba Satellite P745 Laptop. I've suddenly lost my WIFI network and can't connect to the internet. The wireless icon does not show on the laptop; FN F8 button does nothing. The WIFI driver is showing in Device Manager in the Network Adapter and the driver is updated. I can connect to the internet using ethernet. The WIFI icon is showing green in Network and Sharing Center but it has a red cross by it. I've toggled the WIFI and it gives me an option of turning it on manually, 1 hour, four hours, or 1 day. However, when I click on manage networks or show available networks, I get nothing. Help! I'm at my wits ends.
