HT160 is disabled

Smart Connect is disabled and i tried changing the password for the5g network but it still gets the same error.

I have searched a lot on here and tried a lot of things. any ideas?

Could you please try going to Settings -> Setup -> LAN Setup and reserve IP addresses for the devices that are struggling to connect. Then see if they can connect properly.
