RAP3 with USB Modem K4605

[gianti81]

Hello, we have changed the USB modem connected on RAP3.

Before we used K4505 and it worked without problems, now we use K4605 and we don’t have the device string and device ID for this modem.

Someone can help me?

Thanks and Best Regards

Hi Gian

Can you post the params you were using for the K4505? Huawei devices tend to all be using quite similar modeswitch etc., so let's start with the config that was working before.

Looking online there are a couple of versions of K4506, so we do need to determine the "product ID" that yours is using. Please take the USB modem and put it in a windows pc, connect it to the internet using the USB modem then visit device manager -> ports (COM and LPT). You should see the Huawei (or perhaps named as Vodafone) modem listed under this section, right click on it and choose "properties" - a small box will open which has a tab called "details" - click this. Finally, in the dropdown box that now appears choose "hardware IDs" and copy out the string you see, it will look something like this:  USB\VID_12D1&PID_1003&REV_0000&MI_01

HI Gian,

for a first attempt, please set device ID to 0x12d114c6 and leave everything else the same. If that fails, we can try modeswitching it - but let's try easiest way first.

Thanks for your quickly reply. It was my first test :-) ... but without positive results.

Thanks for your support.

ok, then let's try to modeswitch it. Please add the following, leaving the device id as in my last post and configure this in the USB modeswitch field, including the double quotes.

"-v 0x12d1 -p 0x14c1 -M 55534243123456780000000000000011062000000100000000000000000000"

Thanks for your quichky reply!

I have added the USB modeswitch as you suggest, but the Controller requires backslash before double quotes, so I have added it in this format:

\"-v 0x12d1 -p 0x14c1 -M 55534243123456780000000000000011062000000100000000000000000000\"

Nothing to do... it doesn't work!

Regards,

Gian

controller CLI shouldnt need backslash, webui may want single quote, can you try both?

[gianti81]

Only one info: in the old configuration (where K4505 works) I configured:

USB Device Identifier: 0x12d11464

USB Dial String: ATDT*99***1#

no USB modeswitch

Now we have changed the USB Device Identifier to : 0x12d114c6 and added the USB modeswitch as you suggested.

In this new config USB Dial String field will be the same or I have to delete it?

Best Regards

Hi Gian

yes, dialstring should remain the same - the changes are the device ID and adding the modeswitch string.
