Hi @NevenS 

Thanks for posting in our business forum.

Use the beta firmware instead of the V2.2.2 and try again.

Hi,

 

When I rebooted after the firmware upgrade it was Connected for some minutes and now back to:

No USB modem is connected.

 

This is a screen and my settings. And my USB modem is blinking RED and GREEN. When the USB modem is working direct to PC then its green and working fine.

 

Did you use manual config before? Or you just changed this and it leads to a problem on the connection?

Blink green and red usually indicates it got a problem with the connection.

I think you should consider your config then.

Question: do you use auto config with the USB modem when it is plugged in your PC?

Hi @NevenS 

Thanks for posting in our business forum.

This is not a modem. It's more like a mobile WIFI router.

Did this work on your ER605 before? I am suspicious. How did you set it up before? I am sure that this is a config issue. Because you need to dial the Internet. This Huawei mobile is in router mode. This does not match the USB modem configuration.

Do you have this personal option?

Don't have any other solution to this. 4G/3G USB Modem Compatibility List for ER605

If you have upgraded to V2.1.5 Beta and it still cannot work, you can try to downgrade to 2.1.1 and see if it can work or not.

Hi,

 

I had an older version of firmware 2.0.0 Build 20220106 Rel.56391 and it recognized an LTE router (Huawei E3372-325)

I am only saying this because you said it was working. If it does not work ever before, then it might be a compatibility problem with the modem.
