My macbook can't find home wifi
My macbook air can't find the home wifi. It can, however, find the neighbours' wifis. The home wifi is working fine with my other laptop and iphone so the wlan router is working.
I can't add the network by manually entering its name (says "no network found")
This happened suddenly without any changes to my computer or the wifi settings.
My computer is a 1-year old macbook air. I haven't found any threads with a real, working solution for this issue so any help is greatly appreciated!
Thank you
MacBook Air, Mac OS X (10.7.2)
