Mac has lost wifi - getting connection timeout.
My macbook has suddenly stopped connecting to wifi networks. Have done all the troubleshooting suggestions and even took it to the Mac store and had the Airport Antenna replaced. Worked fine in the store and now back at home, I can't connect with my networks. No recent changes to the router or network and all other equipement (iphones and pads) work fine. Anyone else having this problem?
