3G Modem on MSR 20-11

3G Modem on MSR 20-11

Dear support staff/members,



I am trying to configure a 3G Huawei E156 modem on a MSR 20-11 router but I can´t see a Celular interface as it should have been recognized/detected.



Could it be a COMWARE/BOOTROM issue or MSR 20-11 doesnt has a Celular interface?



Relevant information:

COMWARE version 5.20 release 1618P07 - msr201x-cmw520-r1618p07.bin

BootROM 1.18



Also if any collegue could recommend/share a howto or configuration guide concerning the Celular interface services it would be much appreciated.



Thank you very much indeed.

You need to use the version 1807 or later.

Hello, jforti.



Thanks for the clarification.

In fact, I had that topic created before we had

our telephone conversation.



It was a firmware version issue.



It works very well. The interface was activated at the first traffic notice and it was stable. The throughput was just as expected for my 3G ISP/provider on my region.



As a side note, I would like to add that the required firmware needs more flash space than the out-of-box specs offer for that model(or at least the one I had on my hands).
