Hi,

We have two identical RB922 boards with Huawei LTE Modems. Earlier this week we upgraded both to the latest firmware 6.42.6.

Following the upgrade neither boards will connect to the internet via the LTE interface. I have noticed on both that the "R" is missing when running
Before teh upgrade everything was working fine and we haven't made any changes to config.

Does anyone have any idea's. Obviously several reboots have taken place, resetting USB power, disable / enable interface etc

Thanks

Sorry, forgot to mention i have also reset the config back to basic and set the LTE interface up from scratch on one and still unable to get the LTE interface into a running state

I have the same problem. I'm running RouterOS 6.44 on an LtAP mini LTE kit .. the SIM card itself is working if inserted in my phone .. same APN configuration is on both my phone and the RouterOS .. I don't know what's wrong !!

What antenna are you using?
Upgraded the firmware of the routerboard and of the modem?

Regards.

6.44.3 totally same problem here. If I type into the terminal /interface its start working.
