Resolved What gives, Apple? Recent EFI messed up my 2011 MacBook Air's WiFi.

Had zero problems with my MacBook Air's wifi... until the recent EFI update. Now whenever it wakes up from sleep, it won't connect to a known wifi network. I have to explicitly connect, or turn wifi off, then on again.

What gives, Apple?!

Anyone else having this issue?

EFI and wifi issue

Had same problem after EFI update...no wifi connection waking from sleep. did a SMC reset and that fixed it.

That fixed it for me, too!

Thanks!
