WiFi keeps changing from 2.4GHz to 5GHZ

[suey3]

I have a EE 4GEE Home Router 3 (2021) and on the back it says 2.4GHZ. I have found over the last few weeks that the signal drops out and then connects for my phone and laptop but it is alternating between 2.4GHZ and 5GHZ. It is frustrating as it stops me working for a while until it reconnects or affects Teams Meetings quality. The other problems are my TV settings for Netflix, Roku etc as it keeps wanting me to log in as the wifi has disconnected and it has changed GHZ and my wifi printer won't connect all of a sudden. At the moment it isn't showing the 2.4GHz connection for my phone or laptop and if I try to add as a new network it says not found. Next door also has the router I have and I can see both 2.4 and 5GHz in available networks in my phone and laptop so where has my 2.4GHz gone?

I'm not sure. That's just some status. I'm after settings. I need its context. Post an image of the whole page incl. its surrounding menus & tabs.

No, that's just your PC. I'm asking about the mobile router itself.

[suey3]

I don't know where to look?

Login to your MBB router at http://192.168.1.1 with username/pwd as "admin"/"admin" or with the admin password found on a label on it.

Sorry went to log on to personal laptop as was on work one but said connected to 2.4GHz but no internet so had to connect to 5GHz with password and now on. Is this the page?

Now press "Log in" & use the admin pwd on the label.
