Qualcomm Gobi WWAN modem no longer appears in Network Manager

Solution 1:

Ok,

Mi Thinkpad has this modem, and now it works.

1. Get a Windows with this driver (for Windows) working. If you don't have, want dual boot, you can try a VirtualBox installation. Get the drivers, and ensure it works with Windows.

2. Install gobi-loader

   sudo apt-get install gobi-loader
   

3. Copy these files, from windows to Linux

sudo mkdir /lib/firmware/gobi
sudo cp -p '/windows/c/Program Files/QUALCOMM/Images/Lenovo/UMTS/amss.mbn' /lib/firmware/gobi/
sudo cp -p '/windows/c/Program Files/QUALCOMM/Images/Lenovo/UMTS/apps.mbn' /lib/firmware/gobi/
sudo cp -p '/windows/c/Program Files/QUALCOMM/Images/Lenovo/6/UQCN.mbn' /lib/firmware/gobi/

Be careful because your Windows filesystem may vary

Restart

It should work

COMMENT: You can also, mount your Windows partition, if you want in /mnt and therefore pick these files from that place

Solution 2:

I think you missed the part about manually copying the firmware files manually in the previous answer. I had a similar issue with a friend's netbook. It was an HP Mini 210–1076NR, but same gobi loader issue.

I blogged about it a while back, it was for Ubuntu 10.10: http://csgeek-random.blogspot.com/2011/02/hp-mini-2101076nr-ubuntu-netbook-1010.html

The relevant part though is probably this document:

Depending on your provider, you'd need a different firmware file. You won't need to re-install gobi-loader each time, but you'll probably need to reboot at least when you change firmwares. Try messing around with the files 'till you find the right one.

I'm not sure if those codes are unique to HP or not, I would go based on the HP document.. if all else fails, google around I'm sure whatever vendor you have will have a document on some cryptic website with this information.

Hope this helps.
