Connection Time Out WI-FI - Macbook Air
Hi! I have a Macbook Air, and have recently updated to Mountain Lion OSX. My Wi-Fi appeared to work properly, but since two days, my Wi-Fi keeps giving the following error: 'Connection Time Out'. What to do? I have changed router settings already. Also, I deleted the prefered networks and updated most settings. It still doesn't work. HELP!
MacBook Air, OS X Mountain Lion (10.8.1)
