I got my Toshiba laptop 2 years ago. Everything was working fine and some time ago my computer had a virus. I had to completety wipe out my computer to get it off. When I did, thats when my wifi stopped working. It has a little picture in the bottom bar that had a computer and a red X over it. I got an ethernet cable but I don't want to lug around a large cable just for wifi. When i take out the cable my computer is not able to find any wifi sources. Currently I use a cable but I would like to figure out how to restore the wifi on my computer without a cable. It is not the modem or routers problem because everything else in the house can connect without a problem.
