XB8 and Sonos app connectivity

Yes, the following info was my fix

Sonos Problem:  Sonos could not join my network from either my Sonos MacBook app or my iPhone Sonos app. “System not found on my Network”

Things that didn’t fix the problem:

Deleted network and reinstalled many times

Deleted Sonos app on MacBook and iPhone 13 and reinstalled many times

Reset Sonos app on iPhone many times

Restarted Xfinity XB8 Gateway via Xfinity app and by unplugging many times

Split networks with the Xfinity app many times

Added static IP addresses within eero app (Settings:Network Settings:Reservations & port forwarding:Add a reservation: (I added all my Sonos devices)

2 Things that fixed the problem

XB8 Gateway Bridge Mode needed to be enabled (login 10.0.0.1). (Ironically, in May a live Xfinity tech disabled Bridge Mode and told me never enable Bridge Mode)

iPhone 13 Wi-Fi Assist needed to be turned on even though my iPhone was sitting right next to my Gateway (iPhone:Settings:Cellular:Scroll down to Wi-Fi Assist:Turn on)

Although adding static IP addresses did not fix my problem, I left them as static in the eero app

I received excellent support from the Xfinity Forum folks via DM and from the eero technical support group. In addition, Sonos support also provided assistance.  It was the Sonos Community that suggested the last fix i.e., turning on Wi-Fi Assist. I thank them all for patiently working with me. And a shout out to Aire Theater Designs for suggesting the static IP addresses (search How to fix Sonos).

I, like many other Sonos users, was ready to scrap Sonos. But now that it’s “back to normal” I’m glad I persevered. I just wish Comcast would have credited the $100 service visit since they disabled Bridge Mode in May that contributed led to this problem.

Hope this helps
