I thought I would pass some info on for anyone with the XB6 who is having random connection issues, or random reboots.
I was having both, and the Shaw techs couldn't see anything wrong on their end.
The fix? Go into the settings and disable the MoCA network. It isn't being used on the XB6 at this point anyways. That fixed EVERY issue I had. It's been flawless for me for a few weeks now. Before I disabled it, it would drop internet and reset at least once a week.
Just thought I would pass that along.
