Sierra Wireless HSDPA WWAN ModuleThis is a Sierra Wireless WWAN Adapter that is installed in a Mini-PCI Express slot. There are three versions that mainly differ in the supported bands. The MC8765 is meant for the North American market, while the MC8755 and MC8775 are meant for the rest of the world. They are also known in Lenovo literature as
NOTE!
Specific versions of this card may come pre-configured for a certain carrier (AT&T, Vodafone)

NOTE!
Not all ThinkPads listed below can have this option installed, check if yours is WWAN upgradable first. Also installing the wrong card type in a ThinkPad that never officially supported it may give a Error 1804 on boot and refuse to continue until the card is removed. As such it is best to check the HMM (Hardware Maintenance Manual) for your ThinkPad first.

Linux support
Should be automatically detected by NetworkManager with any recent Linux distribution (Fedora 12, Ubuntu 9.10) and allow for easy configuration.

Sierra Wireless MC8765 1199:6805 support
The model 2613-ETU T60p (and possibly others) has one of these cards which the linux sierra device driver does not automatically recognize (as of kernel 2.6.24.4, at least). Using the 2.6.23+ hotplug infrastructure, we can cause the driver to claim it anyway and register serial devices in /dev for it.
To do this using the udev subsystem, edit or create the file /etc/udev/rules.d/98-local.rules file and add:
######
## Sierra Wireless MC8765 1199:6805 support
##
## My model 2613-ETU T60p contains a WAN device which the linux sierra
## device driver does not automatically recognize. Using the 2.6.23+
## hotplug infrastructure, we can cause the driver to claim it.
##
## The 3-port interface works with this device, but there's not much point
## in registering the 2nd and 3rd since they are used for control purposes
## that we don't currently use under linux.

# TODO: fix this:
# This isn't quite right for sierra3, since it will always symlink
# wan_modem to the last created device; in the 3-port case that's not the
# device we actually want to refer to for modem interaction (we want the
# first device). We could limit this using ENV{PHYSDEVDRIVER}="sierra1",
# but udev warns that this is deprecated and will be removed from a future
# kernel.
