Raspberry pI 4 with EC25AU

I am using a raspberry pi4 (bullseye os) with usb adapter for EC25-AU

I set one of these up and it worked fine on firmware, EC25AUFAR06A06M4G

But when I set this up with firmware, EC25AUFAR06A10M4G_01.001.01.001
I get QMI error 14 constantly. I am not 100% sure if it is a sim card issue or modem BUT the sim card works in another router with ec25 I use all the time.

Do I need a firmware upgrade and also what is the latest firmware for this model? What else can I check?

Hi @Justnz
Can I ask where you use it? Also, have you tried upgrading the original firmware?
