The Lenovo T430s I have for work comes with a Verizon Wireless 4G card built-in. It took weeks to get it working on Windows 7. Turned out that I had a bad SIM card.
Once I was able to get it to work in Windows, it was time to get it working in Ubuntu.
The USB ID for the MC7750 is 114F:68A2. It is also listed in Windows as “Gobi 4000 HS-USB Modem”.
Ubuntu didn’t recognize the 4G modem out of the box. I found a driver here. Here is more information. This modem wasn’t in there, but I went ahead and modified the source to add in the USB ID. Here are my diffs:
Save these to the folder where you downloaded the driver. Then
tar xvf v3.2_1740_kernel-3.0.directIP.tar cd v3.2_1740_kernel-3.0.directIP patch -p0 < ../sierra.patch patch -p0 < ../sierra_net.patch make sudo make install
and then reboot.
Success! Or sort of. It showed up as registered on Verizon. I could see the signal strength. Finding the right settings for NetworkManager is the next step.
There are three options for the number:
#777 *99# *99***3# *99***4#
The username should be the [email protected] and the password is vzw.
I’m still working on this. It isn’t dialing, but I’m having a hard time finding the right combination.
