I have 2 Deco X55s (ethernet backhaul) connected to a Pace 5268AC Gateway with incoming ATT Fiber (500Gbs).  The ATT Gateway WIFI is turned off. 

Since the Decos were connected and setup for WIFI, the ATT Uverse TV DVR device (Motorola VIP2250 connected via HPNA) has had problems recording more than 1 show at a time. I reported the problem to ATT Uverse Support and they sent me a replacement DVR, an Arris VIP2262. But the replacement DVR is having the same problems.

I disconnected my Decos temporarily and found that the ATT Uverse DVR can now record multiple shows simultaneously!

I am not using the IPTV setting on the Decos and they are in different location than the TVs so I cannot use a port on the Decos for IPTV.

Is there anyway I can configure the Decos so they DON'T interfere with the Uverse DVR?

Thanks
