Linksys WRT1900AC 5ghz Wireless "Device is not active" and "Wireless is not associated" with same SSID

I set both SSIDs to be the same, just like documented here: 2.4 GHz and 5 GHz under the same SSID or separate ones?, but now I'm currently getting the attached errors.

Here is my /etc/config/wireless. Anyone see anything glaringly wrong?

I have been having issues with my 5g as well with the same router: Linksys WRT1900ACv2. I came on this forum to see if others had reported the same thing or if my hardware was starting to go. I am going to try downgrading to 19.07.2

I have been having issues with my hardwire internet as well. Have to see if the downgrade fixes that too.

edit: Downgrading to 19.07.2 lets me connect using 5ghz wireless. Will let you know if my internet connectivity recovers as well.

Are you using the same SSID for 2ghz and 5ghz?

I use different sids. I should note that I selected a specific channel instead of using auto. I first noticed dropping connection when turned on auto. Since then I have been having issues. Not sure if it’s in combination with upgrades.
