After all the issues I used to have with an older AP One, I switched for ~14 months to one of the simple Unifi POE WAPs, but I was having really bad issues requiring me to reboot it every couple weeks, and then later on every few days and it culminated into having to reboot it every few hours to keep connectivity up, at which point I upgraded to an AP One AX.
I’ve had some issues with 2.4G devices randomly dropping out with the AP One AX, especially the Vesper Cortex. I’ve set my BR2 Pro and AP One AX up to reboot every week at 4am Sunday morning. That’s virtually eliminated problems with my AP One AX. What kind of compatibility issues are you seeing?
