2.4g devices not connecting to T-Mobile Home Network
Recently I set-up a T-Mobile 5G Home Internet and am discovering that not all my devices can connect. My Shark IQ Robot vacuum is one device that will not connect to 5G, it says it can only connect t...
Yall are making this WAY harder than it has to be.
1. Open the T-mobile Internet app
2. Go to the Network tab at the bottom
3. Click on the "+" sign to add a network
4. Add in the information for a 2nd network and change the frequency band to 2.4 GHz.
Done. Easy. Now you have 2 networks and 1 is 2.4 only. I had to figure this out myself as this thread was trash.
I always recommend leaving the default network alone and using it when possible. (You can change the SSID and password.) The default network automatically selects either 2.4 or 5 GHz for the connected devices, and uses the highest current level of security WPA2/WPA3.
Some devices, particularly older ones, work best on a dedicated 2.4 GHz network with WPA/WPA2 security. Because the security is not as good as possible, this should only be used for devices which just won't connect to the default network.
You could have a dedicated 5 GHz network for some devices, though in my opinion it isn’t necessary.
Re. Sonos -- I was able to get my Sonos speakers to connect to the default network. It was stubborn but I can't remember exactly what I did. I recall searching Sonos support and forums but not finding much help. I do think it was just persistence. My speakers are probably older than yours - they are Play:1 and Play:3. It is easier if you can temporarily move the speakers to be closer to the gateway. If you changed the band or security on the default network, I suggest resetting the gateway to restore the original configuration. Add a second 2.4 GHz network for devices that won't connect.
