No Internet (22), but can download VOD

Equipment
1 - HR24-500
1 - HR21-200
2 - H24-100
AT&T U-verse RG - 2Wire 3800HGV-B, DHCP enabled
SWM, DECA install (including broadband DECA)

Error 22

Here are the diagnostic codes from all of the receivers (from the test in the main menu) if that helps in any way.

HR24-500 - 71-965
HR21-200 - 71-73-827 (side note, this is the only receiver that doesn't have a phone line plugged in and part of the error is the phone connection)
H24-100 - 71-040
H24-100 - 71-847

I've power cycled all equipment (receivers, broadband DECA, and router). The configuration had been working up until recently (not sure when it went out specifically, and no changes have been made to the set up).  The router firewall is the default from AT&T U-verse and it can still connect to download VOD.  It has been working without a hitch since I had the SWM/MRV/DECA install back in May, until now.

Any help is appreciated.
