X6S Mesh Extender/C7800 keep disconnecting
I've a C7800 provisioned by xfinity and an EX8000 extender (firmware v1.0.1.240) extender. They are (almost) line-of-sign through a doorway. The EX8000 disconnects from the C7800 at least once daily,...

Did you set them up using wps?
If so, factory reset the ex8000. Using the installation assistant to reinstall. during the install process, uncheck the "extend 2.4ghz" network. You'll still be able to use the 2.4ghz but it won't act as failover for the backhaul. You can also try changing which channel t he C7800 uses for the 5ghz in case theres issues/interference on it.

Thanks - I'll give this a try and report back.
Quick question: can you explain your thinking on the recommendation to disable the "extend 2.4 GHz network"?

Reason I say uncheck that is the EX can use the 2.4ghz as failover for the 5ghz. So if there's issues with the 5ghz, it'll use the 2.4ghz. Problem is that the 2.4ghz is incredibly slow and significantly increases ping times. In my experience, its better to disable the 2.4ghz failover and find a stable 5ghz channel for the backhaul and just stick with that.

Regrettably I'm still getting the disconnects. There doesn't seem to be any change in frequency of occurrence or any other symptomology. Nothing is apparent in the router log files. (If there are log files on the extender I don't know how to access them.)

Do you have a screen snip of the extenders status page?
