Cellular M2 5G Board (RM520) no 5G internet (only 4G)

Routers

Hi all,

I am using the M2 5G board on a Flint2. The connection to the 4G network works smoothly, but the module does not switch to the available 5G network (neither SA nor NSA). The same SIM card works fine at the same location with my Netgear Nighthawk router on the 5G network. Therefore, I assume it is a configuration issue. The location is Germany, the operator is O2/Telefonica, and the APN is either “internet” or “netpublic” for IPv4.

Can anyone help?

Hi, please check whether all antennas and ipex cables are connected properly.

Run this AT command to query the network search mode:
AT+QNWPREFCFG="mode_pref"

And use this command AT+QNWPREFCFG="mode_pref",NR5G to set search mode to 5G to see if it helps.

I think it depends on firmware issues of my current RM520NGLAAR03A03M4G_01.201.01.201. But I am not able to flash my device with RM520NGLAAR03A04M4G_01.204.01.204 due to missing AT commands to enter edl mode.
