Shibby mod - 3G USB sticks

    Recently tested the Shibby's mod with 3G sticks. Works really well and customizable. Stable and excellent throughput using a LTE USB stick (Novatel U567) http://www.draisberghof.de/usb_modeswitch/bb/viewtopic.php?t=857


    I tested a Sierra Wireless USB LTE stick (http://www.sierrawireless.com/en/productsandservices/AirCard/USBModems/AirCard_313U.aspx), and it would seem that Sierra has gone in the direction of presenting their LTE sticks as ethernet interfaces. They have legacy support for a PPP stack (through ttyUSB3) but the USB stick keeps disconnecting after some period and causes traps.

    Any possibility of compiling the sierra_net.c driver? I would like to "modprobe sierra_net".

    Any suggestions would be appreciated.

    it would be good that shibby's build would support HSO module (and many option 3g sticks) but i think the chance is very little because everything i write regarding HSO module is being ignored.

    this would be really cool. i'm also into the same problem with a 754S sierra card.

    I third this wish. Upgraded to the latest/greatest tomato-Netgear-3500Lv2-K26USB-1.28.RT-N5x--114-AIO hoping it had in-built support for my Sierra Wireless AirCard 762S (AC762S) [ID 1199:68a3 Sierra Wireless, Inc. MC8700 Modem] but w/o success. After several hours searching the few suggestions found indicate that it needs a) sierra_net (missing) or b) netcfg attelevate (not supported in tomato? - https://bbs.archlinux.org/viewtopic.php?id=135981 ) or c) sending at-commands to the modem (no clue at yet how but some info is available here: http://mycusthelp.net/SIERRAWIRELESS/_cs/AnswerDetail.aspx?sSessionID=&aid=5 and here: http://mycusthelp.net/SIERRAWIRELESS/_cs/AnswerDetail.aspx?aid=44 ).

    1199:68a3 is a Sierra Wireless modem running DirectIP firmware. It has several serial functions (AT, CNS, DM and possibly GPS) all managed by the "sierra" driver, and a DirectIP network function managed by the "sierra_net" driver. Both drivers are available in any recent Linux kernel. They are also available for download from Sierra Wireless for older kernels.

    You can choose either to connect using PPP over the AT serial function, or using the wwan0 network interface. In the latter case you need the AT function for device management (configuration, connect/disconnect etc).

    Sierra Wireless has documented all of this quite well:

    Any hints how to move forward? The 762S is specific to the Finnish market but a sister product is sold in Australia and is very common in both countries for wireless LTE. I had the unit running fine in Ubuntu 13.04 after creating
    /lib/udev/rules.d/81-mm-sierra.rules with these two lines:
    SUBSYSTEM=="tty", ATTRS{idVendor}=="1199", ATTRS{idProduct}=="68a3", ENV{ID_MM_CANDIDATE}="0"
    SUBSYSTEM=="net", ATTRS{idVendor}=="1199", ATTRS{idProduct}=="68a3", ENV{DEVTYPE}="net"
    NetworkManager found wwan0. This broke upon upgrading to 13.10 (kernel bug?). Until I get this fixed, I am stuck using a borrowed Huawei LTE stick.

    Anyone tried to compile the sierra_net module for Sierra 4G devices?
