I have the TP Link Deco x20

I have ATT Uverse

I got everything to set up & it was working

I have a separate line for my work, that my work pays for & it connected to the mesh too (which I didn't want it to do).

That was 1 thing

The biggest problem I have is that I can't pause, fast forward or rewind my live TV with the mesh connected.

I unplugged it because I use these features constantly & not having them is unacceptable.

I kept getting an error that there were too many TVs watching live TV & that is why it wouldn't work

BUT, there was ONLY ONE TV being used!!!!

What can be done to fix this?

If it's not fixable, I am returning it!!
