It looks like the device is underpowered, the MT3000 USB can only provide a maximum current of 1000mA, from what I understand, the maximum instantaneous current of RM520 can reach 3000mA+

3

3000ma+ is peak usage. But the problem is in 4.2.0 its not showing in the attached modem. And in the 4.1.3 its showing once its connected kernel might be panicking ?

4

First off all device is not detecting in 4.2.0 version. In the root shell i can check and able to see the device able to connect with modem managed (Needs to be installed with QMI)

I think this is a random event, depending on whether the modem is powered down at the page refresh.

6

I can reproduce consistently.

7

Perhaps you can try turning off the 2.4G wifi to reduce the current consumption in other parts.

8

Will it supply more than 1000mA in USB port for peak?
How much will it supply if i turn off both Wifi bands ?

You didn’t mention how is the modem setup but most interface cases I see for 5G modems have their own separate DC input. I doubt it will work if you are purely relying on the USB port provided by the MT3000 to power the 5G modem completely. The router alone can use up to 3A and the provided power brick doesn’t give more than 15W (5V*3A)
Worst case scenario, router needs at 5V, 3A and the modem another 3A… 6A at 5V!!!

10

That’s a good point, these latest 5G modems require more power. I think typically their own separate DC 5v 3 to 4A input.

11

I expect that the USB-C port on the GL-MT3000 can provide between 1.2A/6W to 1.5A/7.5W, based on recent routers in this thread:

I do not work for and I do not have formal association with GL.iNet

12

Yes

Thanks for sharing the thread. But i know the issue is power on peak but normal operating should be less than 1000ma so it should work

13

Measure it with a digital tester to know for sure instead of using gut feeling. I had the same continuos disconnections with an EM06 while using the provided 15W power brick.

14

My issue is first modem is not detecting in the router default UI ( i was able to see in root shell connected devices, and using modemmanager i was able to connect but in UI its not showing. Thats the issue i am raising it.

15

I can confirm a similar problem with detection of Quectel EM160R LTE modem - MT3000 v.4.2 / GL GUI does not detect the modem, a new modem interface is not created, but the system log checked from Luci shows that the modem was found on the USB bus. The same modem works just fine on ATX1800 Slate v.4.2 after the fix provided (via remote access) by one of GL-Inet customer support rep :

https://forum.gl-inet.com/t/using-atx1800-with-quectel-em160r-gl/23443/37?u=i7bar

I was told that it would be added in v.4.2 but looks like it was not.
