WRT3200ACM 5Ghz network keeps disappearing

Running OpenWrt 19.07.2 r10947-65030d81f3. Was going to upgrade then noticed something odd started happening.

The 5Ghz network will disappear. I have to go in and change for example the channel. After saving the changes the network comes back.

Repeats the same behavior after a random amount of time.

Has anyone seen this before?


You've driven this WRT3200ACM for a couple years and you didn't say whether you're a heavy wifi user. So I'm guessing, all things aside (Rocking Steady since Jul 26, '20) it needs some TLC. If you've ever broken the case open, perhaps check out the sinks.

SSH in to the router and run cat /etc/config/wireless.

Redact the passwords in the option key sections.

Post the results in preformatted text, by using the icon highlighted in red...
