Honeywell T9 cannot see my ax11000 networks. Help please

[GabrielPhoto]

Hi.
So my Honeywell T9 somehow can see networks from neighbors but it won't see either my 2.4 or 5ghz ones.
They are separate networks with different names and password.
I tried creating a guest network with a short name but that didn't help.
Thanks!

May not be the SSID length. Some IOT clients do not like WPA3 or WPA2/WPA3. I had to set up a guest WIFI with just WPA2 2.4 GHz for a couple of our older clients. Also good to use fixed channels. For 2.4 GHz use 20 MHz on channel 1, 6, or 11.

Late last year I installed a similar one and this helped with the initial setup:
