Hello I have RM520n-gl modem and the problem is I can’t reach 5g connection. Do I need attach all 4 anntenas to this modem? I have supposedly 5g sim-card from our provider.
AT command below
Also you can try to lock to 5G with following command to test.
AT+QNWPREFCFG=“mode_pref” // Query the current network search mode
AT+QNWPREFCFG=“mode_pref”,NR5G // Lock to NR5G
AT+QNWPREFCFG=“mode_pref”,LTE:NR5G // Lock to LTE and NR5G
