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. http://mycusthelp.net/SIERRAWIRELESS/_cs/AnswerDetail.aspx?sSessionID=&aid=44 Any possibility of compiling the sierra_net.c driver? I would like to "modprobe sierra_net". Any suggestions would be appreciated.
