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:

1. Rename the SSID1 name, so it doesn’t share the same broadcast name as the 5GHz band, or ...
2. 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.

 

Dear Tomwil, Is there a simple way to temporarily disable the 5GHz signal without modifying the name of the Wi-Fi network for 2.4GHz, and only keep the 2.4GHz signal? This is because I want to set up a device that only supports 2.4GHz through a mobile phone, but then revert the network back to its original 5GHz/2.4GHz state after the device is set up. Thank you in advance for your kind reply.

By default, the 2.4GHz and 5GHz networks are both on and broadcasting together so when you connect to the network, the device you are connecting can utilize the one that works best for it. When you have a device like your smart switch that can only connect to 2.4GHz, you name that network so you can connect to that specifically and set up the switch. During the setup, you separate the networks on your gateway, connect to the 2.4GHz network on your phone, and then go through the app to manage the switch. After that, you can go back to the wifi settings on your phone and select the 5GHz network to use regularly. There is no need to turn one signal off for any amount of time, and when you change your phone back to the 5GHz network the smart switch will still be on the 2.4GHz and not have any issues. 

I have done this a dozen times with the devices in my home. Hopefully this helps you.
