No clue; the first thing I would try is to reboot the Comcast modem (XB6?) by just unplugging the box and plug it back in.

hello.     in the last 2 days.   today being 8-30-19 in denver co.  using xfinity xfi 2.4-5ghz XB3 wireless modem router,  i have intermittent drop outs of connectivity.  i first noticed it when i got my new laptop and downloaded world of warships to test running my pc through tv via cables.    loss of signal occured around, 12pm noonish 8-28-19,   thats the first time ive noticed it.     now its happening to my fire tv, internet youtube usage,  my laptop and  now my girlfriends work computer.   several months of no issues using just the tv and tablet.     im having to wait a week or so to acquire long enough ethernet cables to run to my room, to test a hard wire connection.    looking at this forum it appears this is a common issue.     im trying to give as much info on whats happening.   i appreciate your time and effort.

I gave up on my XB3 wifi; it just didn't cover enough area.  I replaced the XB3 with an XB6 and purchased the Orbi and my wifi is much better.
