Hi Have AC1200 E4 2 pack which is working. I'm connected to it but if l logged out of it and then reconnect, the password won't work Also other members of the family can't connect cos of the password

My setup is three Deco E4's, wirelessly set up as router in a chain topology. I have some devices that simply refuses to connect to the main network on wireless. They can conect to the guest network w
