MBA not connecting to wifi

[hehe299792458]

Even though I have my router in preferred network list, my MBA still asks me to select a network to join. It says that none of my preferred network is in range, and only shows my router after I "refresh" the list by clicking on the airport icon. My UMBP connect to my network fine. Is there any way to also make my MBA connect to the network automatically?

I have been having this problem too. I tried some of the tricks I found in other threads and they don't seem to work for me. But if I restart my Airport Base Station, the problem goes away for a while. So I think the root cause is my wireless router.

If you're using an Airport Base Station, open the Airport Utility App, then tell your router to restart. That often fixes the problem for me.
