Talk:ThinkPad mobile Internet
New lenovo thinkpads (like my T440s) don't have a QMI modem, instead they have a MBIM modem (see https://sigquit.wordpress.com/2013/02/06/an-introduction-to-libmbim/). In this case, it will also show up as a /dev/cdc-wdm character device, but not handle by the qmi_wwan driver; instead handled by the cdc_mbim driver. There's libmbim (and mbimcli, mbim-network) as well, in addition to libqmi (qmicli, qmi-network).
Also, the comment about needing the Lenovo activation app is simply not true. It may be that the QMI modem is a Gobi2k, which may need firmware loading via the gobi_loader program (that was the case in my old Lenovo thinkpad).
Also, why not suggest using ModemManager+NetworkManager? That is simply the easiest way to manage these WWAN modems. I wrote both libqmi and libmbim to be used in ModemManager. qmicli and mbimcli were just some test tools to check the APIs :)
- Thanks for your comments. Please feel free to edit, I'm not that experienced with this. I only wrote the page as I couldn't find all the information in one place elsewhere on the wiki, but it would be good if the page were edited by somebody who knows more about this stuff.
- W.R.T. your hardware, sure, please update. I'm using a Lenovo X230, which is older. I recommend leaving in the stuff about the Gobi though, because older ThinkPads are still quite popular and common.
