Hello, I have just purchased this modem but sadly i have 2 problems with it. My first problem is when i set network mode to 5G only the router wont connect to the internet or find any bands to connect

Issue 1: When the network mode is set to 5G only, the modem fails to connect to the internet or detect any 5G bands. However, when the mode is set to 5G/4G/3G, the modem successfully connects to a 5G
