After Yosemite upgrade I can't login without an Ethernet connection

I have used my MacBook pro for over three years. I recently upgraded the OS from 10.8.5 (12F45) to 10.10.1 (14B25). I use an active directory account to login with, until the upgrade I only used wireless connection to reboot and sign-in with my AD account. After the upgrade, the last step was to reboot - my login box appeared and I logged in using my AD account like normal - only the login stopped (on the progress bar it was about 1/3 done). I logged in using the local admin account and updated the mac address in the ethernet settings. I then plugged my ethernet cable and was able to see the login complete. But now, anythime I reboot I need the ethernet... which is problematic as I will only be able to do this at my desk. I've googled and seen a few cases where this happens but none match my exact issue. I've tried rebooting in safe mode - and verified there are no disk issues and re-installed the OS.

I'm not sure it's going to help with the wireless problem, but take a look anyway.

Thanks chscag - I did view the video and there were some interesting points made. I am already connected to my AD server so that didn't shed any light on my issues.

It just appears, on sign-in after rebooting or restarting, to require the Ethernet connection. It wasn't like this before the upgrade. When I sign in as local admin I am connected to the domain wireless... so maybe when I'm using my AD account I don't have domain wireless. I know that when I did a Command+R to re-install the OS, the domain wireless was unavailable, only the Guest wireless was available.

I've checked all my network settings and compared them to others in my group and it only seems to affect me. Very frustrating.
