Quectel EC200T-CN LTE module not working in OpenWrt

It's not an issue of a mpcie module in a slot designed for USB modems?

sorry. I didn't get it.

What kind of interfaces (electric, not physical) does you modems use/have ?

I am using this

Never mind, AndrewZ got you...

this is for the USB dongle. My router has a USB interface. I am not using a USB dongle/data card. I am using a module.

Seriously? Don't argue, just do it.

Hi
It's missing drivers/modules.
Should be fine after installing the correct modules.
He's using a zbt we1602, minipci connector with usb quectel lt4 module.

usb device:

USB\VID_2C7C - Quectel Wireless Solutions Co., Ltd.

Hi
This quectel lt4 module IS USB, you internal connector IS USB.
GO for @AndrewZ recommendations.

ok. i am trying @AndrewZ

Sorry for the previous argument.
Actually, I got the IP address on the interface but I am unable to reach the internet.

And I am unable to browse 192.168.43.1 which is its gateway. I have also added the firewall rule.
Please Help!

Try pinging any public IP address from the router directly.
You cannot browse the gateway. You don't need to add any rules, you only need to put your newly created interface in the right zone (wan), which you have already done as far as I can see.

I am unable to ping the public IP.

It looks like this modem is different from the other models you mentioned at the beginning.
You will need to issue some AT commands to setup a connection:

at+qicsgp=1,1,"{your APN}"
at+qnetdevctl=1,1,1

Please do not use images to display text data.

Please can you tell me the difference between EC20 and EC200T-CN?
like why it is not working via QMI Protocol.

Thanks you save my day :sweat_smile:
