Problem with E router and Moto G60S phone

[AntFr]

Hi, Just had EE broadband 900MBPS installed with Smarthub 7 plus and mostly working fine. All except a Moto G60s phone on Android 12 (newest it can run) that can't see the wifi network and obviously cannot connect to it. Also, no other local networks show up as available, that is until I turn off the wifi on the router and reboot the phone. Then all the local networks are shown - until I turn on the router wifi and then all the networks are gone and the phone becomes unresponsive and sometimes goes into a boot loop. I have connected to another network at another location and all works fine (not EE).  I have reset wifi on the phone, reset everything to factory, tried turning off some bands of wifi, but it still seems to destroy the phone wifi capability when EE wifi is turned on. Also configured my old router as an access point and it connects, but no use as when EE wifi is back on the network is no longer visible. A much older Moto G7 connects fine as do several other phones and all of my other devices. There is clearly something not happening with the flavour of wifi being output, but I would like to know if it can be resolved or if the phone has to be replaced.

Anthony input on the cause and possible fixes welcome. Thanks.

Try setting up Compatible WiFi on the router under Advanced > Wireless Settings (it defaults to 2.4 GHz) & connect your problematic 2.4 GHz devices to that.

Thanks for the reply, I tried that but didn't work. I can't see a way to turn off the main wifi but leave the comp wifi active. I turned off 5ghz but still no joy. It is odd it seems to block all other networks so they don't even show up in a list on the phone.

@AntFr This is a far as your old phone goes, so will be WPA2-PSK at the very best and will NOT like the fact your EE Hub is so new. Enable the Comp network with another device that is connected and working, better still do it via the Web Interface and an Ethernet connection to that Hub, http://192.168.1.254 

Comms

WLAN	Wi-Fi 802.11 a/b/g/n/ac, dual-band, Wi-Fi Direct

I'll try again, but my much older Moto G7plus works fine on the wifi - as does a Pixel 7a and many other newer and older Macs. This Phone is only 4 years old - not 5g but pretty new compared to other devices I have.

What I don't understand is why it seems to block all the other networks around me when wifi on the router is on.

@AntFr You can try disabling the the 5Ghz on the main wifi to see if the phone likes, may just be struggling with the dual and in wifi7 mode off operation. It's your phone as everything else is working, unless you can try some options on the phone wireless settings before you start it all for connection!

[AntFr]

I have tried all of the options and still no joy. Even with only 2.5ghz network on it isn't seen by the phone and all other networks are not displayed. Phone is currently in a boot-loop and needs a forced power off to stop. Odd that a wifi signal seems able to cause so much mayhem. Thanks for the tips, but not sure there is much I can do with this.

Are you implying that your phone is in this unhygienic state solely from trying to connect by WiFi to the router? Then there must be something wrong with that phone.

I would tend to agree and my first thought were that it was faulty, but if I don't try to connect to wifi it seems to run just fine.  That's why I tested on another network and it appeared to function as expected with no issues in locating and connecting a network. I will monitor it to see if it works OK without using the wifi - it isn't my daily phone but I will see how it goes. I do think it is using more battery than it should which may also be a bad sign. I appreciate the help. Thanks.
