CAX80 loses 2.4 wifi band

Question

This has happened to me twice in the last month - the 2.4 GHz WiFi band shows up as available, the light on the modem is lit but it cannot connect to anything, nor can anything connect to it. The ethernet and the 5 GHz WiFi band both remain fine and functional. A reboot corrects this issue.

Any ideas as to why this might be happening?

What Firmware version is currently loaded?
What devices do you have all connected?&nbsp;
What channel configurations are currently set on the router?&nbsp;&nbsp;Is Smart Connect enabled on the modem?&nbsp;Any Wifi Neighbors near by? If so, how many?

What devices do you have all connected?
Try setting manual channel 1, 6 or 11 on 2.4Ghz
Does the front LED on the modem for 2.4Ghz turn OFF when this happens?
&nbsp;
Has a factory reset and setup from scratch been performed since last FW update?

This is the second CAX80 I've had, the first one was returned under warranty.I was under the impression that a factory reset was a last-ditch effort, if all else fails. Is that true?
