# This script automate the setup of QMI supported wwan devices.
|
|
#
|
|
# Tested on following environment:
|
|
# * Lenovo ThinkPad X220 (4286-CTO)
|
|
# * Gentoo/Linux, Linux Kernel 3.9.6
|
|
# * NTT Docomo UIM card (Xi LTE SIM)
|
|
# * Sierra Wireless, Inc. Gobi 3000 wireless wan module
|
|
# (FRU 60Y3257, vendor and device id is 1199:9013)
|
|
# memo:
|
|
# I recommend to check if your wwan module works fine
|
|
# for your mobile broadband provider with Windows
|
|
# especially if you imported the device from other country.
|
|
# You may have to initialize your device for your region.
|
|
# * Required kernel config (other modules may be also required):
|
|
# - qmi_wwan (CONFIG_USB_NET_QMI_WWAN)
|
|
# - qcserial (CONFIG_USB_SERIAL_QUALCOMM)
|
|
# * Required settings:
|
|
# - you may have to create /etc/qmi-network.conf.
|
|
# My qmi-network.conf has only a line "APN=mopera.net".
|
|
#
|
|
|
|
# your wwan device name created by qmi_wwan kernel module
|
|
# check it with "ip a" or "ifconfig -a". it may be wwan0?
