Have you tried resetting them to factory settings and setting them up again?
Could be a bug causing the AP to get confused, overheat and slow down.
Update firmware and a reset works for a lot of hardware.
Yeah I did, but I’ve had to reboot them twice this week already so they need to go. They’re running the latest firmware, but BT haven’t updated it since 2022.
We both work from home so it *needs* to be stable.
