Deco M9 in AP mode disconnects other devices when phone gets back in range
Added 2 Deco M9 Plus units in AP mode to my network.
One AP is directly connected to the modem/router unit, other AP is connected upstairs on a switch.
When 2 phones are connected to the network, and phone1 gets out of range, and comes back in range, during the reconnection, phone2 gets kicked off the network.
Also experiencing during the reconnection period complains from phone1 about invalid password.
Is this normal behaviour, or can this somehow fixed?
Is it also expected that both AP units are using the same WiFi channels?
Is there no option to change the WiFi channel, to prevent interference from the neighbours?
Both this setup to upgrade the network, but right now it is causing more headache...
