I have 3 AX55 units (one as a main router and 2 access points) as well as one AX55 Pro access point. I have been setting up wireless schedules to disable some of the radios during the night and during peak electricity hours.

With the AX55s the Wireless Schedule feature seems to work just fine. However with the AX55 Pro I have encountered a bug where after the scheduled radio-off time ends, all radios are enabled, even if they were disabled before the scheduled time. Specifically, I leave the 2.4 GHz radio off all of the time on my AX55 Pro (it's just enabled on the main AX55 router), but if I use a wireless schedule then at the end of the period I have specified the 2.4 GHz radio is automatically enabled. Rather than disabling it manually every day or just accepting that the 2.4 GHz radio will be enabled, I instead disabled the Wireless Schedule I had set up on my AX55 Pro.

I have also noticed that the Tether iPhone app supports wireless schedules for the AX55, but not the AX55 Pro. I am guessing this is a known issue.
