I have been chasing down an intermittent outage issue for several months. From what I can tell, the mesh network seems to get overwhelmed(?) with new devices connecting, and everything disconnects. For a while, I thought it was a stubborn XB3, which required manual reboots about once per week, in addition to the symptom described. I replaced that with an XB6 a few weeks ago, which seemed to resolve the need to manually reboot the gateway. But the unexplained WiFi disconnects persist.... not fun during stay-at-home orders when the kids are zooming or gaming, and mom or dad is working.
This morning when my wife turned on the Xi6 box, all WiFi connectivity was severed, and the xFi application informed me... again... that the network looked good but the pods were offline. Is it possible that this wireless box, and the combination of other devices, are creating this issue for me?
XB6 + 3 Pods
Typically connected devices:
Various assortment of phones, pads and PCs (10)
Thanks for any troubleshooting ideas! Today, I'm going to pull all of the pods and see if that improves things...
I pulled the pods off the network two days ago, but the issue happened again this morning. Calling Comcast, we went through every diagnostic the agent had, mostly plant/off-premises... which is not the issue. This is software running on the gateway, has to be, since I have seen the issue repeat itself on XB3 and XB6, with and without pods connected.
I have no new theories, but a better way to describe the symptom: the WiFi radios on the gateway reboot, knocking all devices off the network for ~5-10 mins. Happens at least twice a week, always in the mornings between 8-10 am.
Is there any way to investigate what might be causing the WiFi radios to reset?
As best as I can tell, both frequencies are affected by the issue. Everything loses wireless connectivity. When I checked during this last event, the 2.4 GHz channel changed from 6 to 11.
