Upgraded to 4.1...system is gone.

I upgraded to 4.1 and now my system won't recognize any of my components. I can find my bridge but when trying to enroll my play5 it won't find it. This happened the last time I upgraded and took me hours of rebooting, power cycling, etc...

This is very frustrating, especially when I HAVE to upgrade to and ruin a stable system.

I ran a diagnostic because that seems to be what tech support is asking for, 3043078.

PLEASE help, this is frustrating!!
