I have a ASUS RT-AX58U (primary / first floor) and RT-AC3100 (node / second floor) setup with AI mesh network. I decided that I wanted to place all my IOT devices such as thermostats, Harmony Hubs, Doorbells, Rachio controller, sump pump float, ect on a guest network. These devices all work in the 2.4Ghz band. My problem is that when I connect these devices to the guest 2.4 Ghz network, everything connects to the RT-AX58U router regardless of proximity. Some devices are closer to the RT-AX58U and some are closer the RT-AC3100, but everything connects to the primary router only when using guest network.
I tried manually binding the closer devices to the node router, but it stated the signal was too weak, despite closer proximity.
To troubleshoot I moved the RT-AC3100 node within 3 feet of the second floor wall thermostat and it would still only connect to the RT-AX58U on the first floor, maybe 30-40 feet away.
Next I thought that maybe the RT-AC-3100 had a weak 2.4 Ghz signal, so I moved the RT-AC3100 to the first floor (primary) and moved the RT-AX58U (node) to the second floor. Even with the RT-AX58U router within 3 feet of the second floor thermostat, but it would only connect the primary router, this time a RT-AC3100 on the first floor.
I went back and the RT-AX58U (first floor / primary) and RT-AC3100 (second floor / node). This time a connected the second floor thermostat to the main network and its made a connection to the RT-AC3100 node on the second floor.
So it appears there is an issue with using guest network with 2.4 Ghz band. I don't think its a hardware issue.
I have already installed latest firmware and did multiple factory resets without any improvement.
I have been in contact with ASUS customer support, but after 1 month they have not been helpful. They suggested I disable roaming assistant and use roaming block list which did not help.
Any suggestions would be appreciated....
