I just recently installed the Deco M3 mesh system in my house. I use U else for 6 televisions. 3 TVs are wired, 3 are wireless. I have the U-verse modem in pass thru mode and I have its Wi-Fi turned off. There aren't enough ports on the U-verse router, so I have a network hub installed. In the hub I have 1 wired TV, and 2 Ethernet cables going to 2 different laptops. 
 

On one wired TV, I cannot pause or rewind live TV. It tells me there are too many TVs, but it happens when there is only 1 TV on. I found this old post which describes my first problem exactly:

My second problem occurs on a wireless TV. If I try to rewind and fast forward live TV, it hangs a bit, then tells me it has jumped to live TV. 
This Channel jumped to live TV to allow TV viewing or recording on the DVR receiver

Is anyone aware of a fix for this? Are there other settings I should try?
