@necktru Did you try to enable OFDMA in it?

So, I can confirm now, that downgrading firmware and updating it again fixed OFDMA bug, without resetting router to FD. I hope you fix it in next firmware, I'd like to use OFDMA.

@Kevin_Z Yes, that what I meant. Yes, it's AX73. My 2.4 devices are mostly smarthome light switches, and yes, all 5ghz devices are working normally. Yesterday I downgrade firmware on it and then...

Hi @Kevin_Z I have same problem, after enabling OFDMA all my 2.4 devices are disconnecting after several hours. Restart helps, but only for several hours. Disabling OFDMA do not help to fix it....
