RB751 and Sierra AirCard 320U

Fri Feb 17, 2012 4:09 am

Hi guys,
I couldn't find anything referring to this model of card specifically but hopefully someone can help out or at least tell me conclusivly that it's a lost cause. I have a Telstra 4G LTE USB dongle (Sierra AirCard 320U) that I'm trying to get to work with an RB751. I'm very new at MikroTiks (although I do have other people helping me as well) but I've been told I need to get the right info and data channels as well as the modem init string, phone and dial command. Does anybody have any info on how I would go about finding them. I've done lots of Googling and haven't gotten very far yet. Anything you could suggest would be great. Thanks.

Hi darthtanion,

Not sure if you have resolved this yet.

I have just been playing with an AirCard 320U and have had good success with one in a RB751 running 5.20

If you just create a new PPP session, you should see a new USB interface "usb2" within the new PPP session.

Select "usb2" and then set "Data Channel" to 3 and "Info Channel to 2.

I used the APN "telstra.internet"

Under the PPP tab, make sure to de-select "Dial On Demand"

Leave all the other settings as default and you should be good to go.

Hope that helps!
