GL-A1300 + usb 4G EP06 not working in qmi mode

eros23 · April 23, 2023, 11:54pm

I installed a usb stick with EP06-E. I wanted to have 4g support on this modem but saw that it doesn’t work in qmi mode. While if I use it on 3G, it works fine…

The strange thing is that I see both ipv4 and dns assigned by my provider but udhcp can’t open the wwan0.

I state that the stick, on ubunu I tested it with qmicli and it works correctly.

This is what I get in my AC1300:

root@GL-A1300:/lib/netifd/proto# ./qmi.sh qmi setup modem_1_1 '{"device":"/dev/cdc-wdm0","proto":"qmi","apn":"web.kenamobile.it"}'
Waiting for SIM initialization
Device does not support 802.3 mode. Informing driver of raw-ip only for wwan0 ..
Waiting for network registration
Starting network modem_1_1
Setting up wwan0

I think you should comment the relevant code in qmi.sh first, then try Y or N and re-setup the qmi protocol.
Also, I remember a similar fix in the latest 4.2.1 version, you can try it, preferably without save the configuration upgrade

eros23 · April 27, 2023, 3:08pm

I tried to install the beta version too but it still doesn’t work. I wonder why the model that has EP06-e works correctly and this, if I insert ep06 usb doesn’t work.
if so I return the gl-1300 router to amazon.

eros23 · April 29, 2023, 3:50pm

I just received the update to version 4.2.1 and it fixed my problem without doing anything!

now, EP06-E also works perfectly with USB.
