2.4g devices not connecting to T-Mobile Home Network


Badge

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 to 2.4G. Does anyone have an idea how I can get this to work?

I had to figure this out myself as this thread was trash

 

Just realize that the option to add a network through the app was only recently available,  not 2 months ago.

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.

Cali Cat, how do you log into the web interface to separate the SSID?  I have the Nokia gateway and am try to access the 2.4 GHz network for my Eufy robovac.

You can use the mobile app or use the web interface by opening a browser to 192.168.12.1

You will need to log in as the admin to access the wifi features. Just remember once you change the SSID you will temporarily be disconnected and will need to reconnect to your new SSID.

If you want step by step, just call TMO home internet support. This is something that all reps know how to do.

Both Nokia (cylinder) and Arcadyn (cube) default to 5 and 2.4G sharing the same SSID. You can log into the web interface 192.168.12.1 and select separate SSID for each and that will allow you to use different SSIDs and passphrase. After you do that, if your 2.4G device requires an app from your phone or laptop to setup wifi, then you have to make sure your phone/laptop is on the same 2.4G wifi. Once setup is completed, you can set your phone/laptop back to 5G.

NanaNise, I understand your issue perfectly as I am having the same one. I have a Wi-Fi enabled split unit (A/C) and cannot connect to my network. The network shows up on my cell phone as 5G and my A/C unit says it cannot find the 2.4G network. T-Mobile just replaced my cellular gateway with an upgrade as the last one stopped working altogether. It was also 5G but my A/C unit connected to it with no problem. I cannot find T-Mobile documentation anywhere that explains how to make the gateway broadcast 2.4G. I’m following this thread and hoping we both get the answer we need. A phone call to T-Mobile Support had me on hold for over 2 hours. I won’t go that route again. Best of luck!

I’m sure I’m not explaining this well, I’ve tried to set up a second network but the app doesn’t have that option. How would I set up a second 2.4Ghz network?

How many devices can you hook up to T-Mobile home internet

Im not sure exactly what you're asking but all of them?

 

I would imagine that if you break 100 it might bog down. There is a 128 device limit in the settings I'm pretty sure.

How many devices can you hook up to T-Mobile home internet

Did you setup your wireless access points? Either by direct PC connection or the App.

You don’t mention which gateway you have, so in brief you can try to separate the 2.4GHz and 5GHz networks for non-WiFi6 connectivity.
