Same here... both devices stuck on the "looking for..." screens. Same WiFi, rebooted both devices. MBP 15" Retina running OS X 10.10.2 and iPad Air 2 running iOS 8.1.2. WAP is an Airport w/ timecapsule.

Tried direct connect too without success, sits at "Password" then goes to "Disconnected"
Tried earlier on my work MBP 13" at the office... no luck there either, hoped it would work at home. No love.
