Wireless Instabilities WRT3200ACM 21.02.1

Hello All
Just recently upgraded from 19 to 21 on my WRT3200ACM.
I saw some mention of wireless instabilities but I appear to be encountering some.
For now, just rebooting and collecting data...

Any advice is appreciated.

OpenWrt 21.02.1 r16325-88151b8303 / LuCI openwrt-21.02 branch git-21.314.39479-e1ccb66
