Further to my previous post is there any Wiki regarding the configuration of modems using the new sierra_net driver? Can't seem to find any instructions anywhere.

Just upgraded an RB411U with a Sierra MC8700 installed. As stated in the changelog an LTE device now appears and the ppp device has stopped working. Unfortunately I cannot get the LTE device to work at all - communication with the device seems to be completely broken, I'm thinking this is due to the...

Thanks for your help Begetan - have read your thread and it seems to make perfect sense that that's causing it. Could you share your script that restarts the modem? (I don't really know a lot about Mikrotik) Thanks!

Thank you begetan for your suggestions :) It's the latest 5.12. tried running at+cfun=1 and also tried putting it in the init command. Since upgrading to RouterOS 5.12 about a month back the modem has actually been a lot worse. This modem is actually used at a clients premises so it's kind of hard t...

Hi Everyone, I have an RB411U with a Sierra Aircard MC8700 in the PCI-E slot. This setup works great when it works with low latency and good speeds. The issue is that after being on for some time (usually around one week) the modem stops responding to the RB411U completely. A soft reboot of the 411U...

Thanks, I wasn't trying to pass that as a command to the API, that's what I want to achieve in API form and I was looking for help getting there - like I don't understand what part of it is passed as a command and what part is passed as an arguement. And when/when not to have forward slashes etc.. I...

I'm using the C# class to connect to an RB411U and I have a very basic n00b question to ask: How does one know what to send in the API to get the equivalent command as the terminal. I want to do the equivalent of: /interface ppp-client info 0 I've tried reading the API documentation but I'm so new t...

Just figured out that the reason I have been having issues is because the modem I have received is a fake. Someone emailed me a few days ago saying they were also having issues and said how their IMEI doesn't look right. Turns out my IMEI is identical! This is the ebay listing: http://www.ebay.com/i...

I also can't seem to get it to connect to 3G - with a telstra and virgin sim card the telstra/optus towers both show GSM and 3G available in the PPP Scanner but it always seems to connect to GSM in both cases. Is there an AT command that could be responsible or is it just my signal? (Get 5 bars on m...

Still having an issue where the modem periodically doesn't respond though, just says usb2:2: sent ATH, usb2:2: sent +++ constantly.

Managed to figure out what it was by trial and error. Needed to add the following to the modem init:

at+cfun=1

Hi Everyone, Firstly I'm new to Mikrotik so bear with me. I have just purchased an RB/411U and a Sierra MC8705 for use as a 3G router. I have been googling for hours and am totally stumped as to how to get this working. It can't detect any carriers in the scan and constantly says "Dialing Out.....
