Error 7 with XB8 Gateway and Xi6 TV Box + Coax Cable TV Box - Propoer Setup

Hello,

I have been reading conflicting reports online that the best way to setup a erro 7 mesh network is to place the XB8 Gateway in Bridge Mode. Then I read how by doing that it will not allow the Xi6 wifi cable tv box to work properly or tie to the DVR properly. I do have a hardwired coax cable TV box too which I assume would be no issue (I do hate to assume).

What is the technically correct way to setup my network up so the erro 7 mesh network works best? My plan was to keep the same network name and password on the eeor 7 network so all my devices connect seamlessly, at least that was the hope. Please share any thoughts or experiences you encountered.

Thank you!
