How to connect a 2.4 G device to 5G gateway?
Recently I set-up a T-Mobile 5G Home Internet and am discovering that not all my devices can connect. My Wopet cat feeder will not connect to 5G, it says it can only connect to 2.4G. How can I get th...
Don’t confuse your “Gs”. TMHI 5G means “fifth generation”. The gateway broadcasts Wi-Fi in your home at both 2.4 GHz and 5 GHz. GHz means “gigahertz” which is a unit of frequency.
Anyway, many devices such as your cat feeder have trouble with the gateway’s default configuration. Here is how to add a dedicated 2.4 GHz Wi-Fi network (SSID) for your cat feeder, and any other devices that have trouble connecting (such as a printer.)
T Life Instructions
Some devices, such as printers, have trouble connecting to the gateway’s default configuration.
You can have several Wi-Fi networks on the gateway. You want to leave the default network alone (2.4 & 5 GHz; WPA2/WPA3 and AES security) and add a second, dedicated 2.4 GHz network. This second network is for devices that can’t connect to the default network.
Using the T Life app on your phone: Tap Connect (at the bottom). Tap Things (at the top). Tap your Gateway. Tap the magenta button Manage. Tap Network (at the top). Tap the magenta + Add Network.
You should now have an “Add new network” page. Under General details, Enter a new Wi-Fi network name (SSID) and a password. Under Advanced settings, change the Frequency Band to 2.4 GHz. Under WPA Version, change WPA Version to WPA/WPA2. The WPA Encryption Mode should automatically change to TKIP+AES. Tap Save at the bottom. Connect your device to this new network.
Use the default network for your other devices, as much as possible. Note that WPA/WPA2 (on the second network) is less secure, so I recommend setting this network to be Hidden. You can hide it after you get your devices connected to it. (The Hidden switch is in Advanced settings, below WPA Encryption Mode.)
I already connected my new tmobile gateway, however, when I try adding a 2nd network it wants me to setup the gateway again???
Revised instructions (the app changed since I wrote the above) to create new 2.4 GHz network:
Tap Internet (at the top). Tap My Wi-Fi (at the top).
At the bottom, tap + Add new network.
General details section:
Enter a Wi-Fi network name (SSID) (TIP: this should be alphabetically after your primary network name.)
Enter a Wi-Fi network password.
Advanced settings section:
Frequency Band: select 2.4 GHz
WPA Version: select WPA/WPA2
WPA Encryption mode will be automatically set to TKIP+AES.
Tap Save at the bottom.
