How to connect my andraoid phone to 2.4 GHz Wi-Fi of T-Moblie Gateway?
I am using a T-Mobile Gateway as my home Wi-Fi network instead of a regular router. Recently, I tried to connect a smart device (a Wi-Fi dimmer switch) to the network using the Smart Life app. However, this device only supports 2.4 GHz Wi-Fi, not 5 GHz. I understand that the T-Mobile Gateway is a dual-band and supports both 2.4 GHz and 5 GHz frequencies, but I cannot find an option to select either of these frequencies exclusively. The auto-connection feature sometimes shows 5G and sometimes shows 2.4G/5G but never displays 2.4G alone (please refer to the attached screenshot). When I attempt to set up the device via the Smart Life app on my smartphone, it always displays the message "Your mobile phone is connected to 5 GHz Wi-Fi. If the device does not support 5 GHz Wi-Fi, please change to 2.4 GHz Wi-Fi" even though the connection of my andriod phone was showing 2.4G/5G. How can I connect to the 2.4 GHz Wi-Fi instead of the 5 GHz Wi-Fi in this case?

Following your instructions, I changed the Transmission Mode of the 2.4GHz network from Auto (ax/g) to n/g and saved the changes (see attached screenshot). However, I am still unble to see a separate Wi-Fi connection on my mobile phone or computer. It still appears as a 2.4G/5G connection (see attached). What could be the issue and how can I solve it?
Even though you lowered the transmission mode of the 2.4GHz band, it is still sharing the same WiFi broadcast name as the 5GHz band.
Two separate options:
- Rename the SSID1 name, so it doesn’t share the same broadcast name as the 5GHz band, or ...
- Select SSID2, enable it, and name it differently from the 5GHz band. This will create an additional accessible 2.4GHz band. You may have to lower the transmission and/or encryption protocols for SSID2.
Tomwil, Thank you so much for your response! However, I would appreciate it if you could provide more detailed instructions on how to split the 2.4GHz and 5GHz bands. Specifically, can you explain how to access the page you mentioned in your previous message? A step-by-step guide would be greatly appreciated. Thank you again!

The T-Mobile Home Internet gateways use WiFi6 ax protocols, which basically combines both 2.4GHz and 5GHz with a shared WiFi broadcast name.
Sometimes, to connect older devices (that use b/n/g/ac protocols), you may have to split the 2.4GHz and 5GHz bands, and/or lower the transmission and encryption protocols.

make sure on the router side that the 2.4 shows up and isnt hidden. could be your issue. out of curiosity though..why does it matter which you are on? opposite side of the house or different floor and not pulling in the 5Ghz that well?
As mentioned above, I'm not using a regular router or modem, but rather, I'm using T-Mobile Gateway. Unlike most dual-band routers that come with separate signals for 2.4 GHz and 5 GHz, although the T-Mobile Gateway supports both 2.4 G and 5 G bands, but it always connects to the Wi-Fi automatically without providing an option to select a specific band when I connect my mobile phone or computer to it. I don't know whether you've used or are currently using the T-Mobile Gateway. If you have and like to share your experience on how to connect a mobile phone to the 2.4 GHz Wi-Fi network, it will be appreciated!
