Not able to set SSID and password for 5Gh band in Dasan H660GM-a router

[unknown-12]

I have the airtel broadband connection and they gave me the Dasan H660GM-a router. I have set SSID index 1 (the first SSID. It provides for for each band) for my 2.4gh band and I am trying to set SSID 2 with different name and password. But it does not save anything when I make changes to 5Gh band. Did anyone face this issue?

This router UI is stupid. Also have u tried changing from airtel app?
Locked router adds _5Ghz at the end AFAIK

For me the UI is greyed out and doesnt allow me to separate the bands

Put the useless thing provided by Airtel in Bridge Mode and connect your own quality high end router frond ending ISP WAN.
NOC team will help you put the ONT in bridge from the backend.

Just disable 2.4Ghz and save and your router will restart and now you will be able to edit it.
