I am sorry but I continue to have errors since the update.
BRUME can not connect/enumerate the GL-M2 from time to time showing below errors which appear since the update to 4.7.4

Please advise how to resolve this:

Hey @AirMax Can you confirm if the power supply of GL-M2 is normal? This requires an external power supply

Hey Jane, yes I can confirm the power supply is normal and I have allways been running it with the external power supply that it comes with.
I have no idea why I continue to have the same errors day by day (at leasr I encounter the problem once a day).

It only happens since I updated the BRUME2 to Firmware 4.7.4

Hi,

We did not reproduce this issue on the MT2500.

Could you please try to connect GL-M2 to PC, to test if the GL-M2 works normally?

May I know if you downgrade the MT2500 to previous firmware version, does the GL-M2 work normally?

I connected it to my laptop and the first attempt resulted in "unable to identify USB device"

So I plugged of the power supply and waited half a minute. Then plugged the power supply in again and attached the USB connector to my laptop and the modem worked like it should.

Sounds like it is a modem issue...? What do you think? Hardware failure or could it be software driven?
It happens every day at least once that all of a sudden the fine working modem stops to work and cannot be enumerated anymore, like it crashed and is stuck in the crashed mode.

I bought this modem in the GL-Inet online shop....

hello, Can you connect GL-M2 to Brume, share the device through Goodcloud and PM me? I will check this issue. Also, I would like to know if you updated the bootloader before updating v4.7.4 version?
