Hello I am having lots of trouble getting my RM520n-GL to work properly on openWRT

The modem when I talk to it in minicom with AT commands says its connected to a 5Gnr network.

AT
OK
AT+QNWINFO
+QNWINFO: "TDD NR5G","310260","NR5G BAND 41",521310

mmcli says different I factory reset the modem and then it’s been doing this, I have no clue how to fix it

Dear @LanAriesEchos

I got it working it somehow got switched to PCIe mode instead of USB mode. I didn’t think that was an option on mine.
