[Bug 1454361] Re: WWAN device no longer works in 14.04 or higher


mpchlets, as per http://support.lenovo.com/us/en/products/laptops-and-
netbooks/thinkpad-x-series-laptops/thinkpad-x1-carbon-20bs-20bt an
update to your computer's buggy and outdated BIOS is available (1.06).
If you update to this following
https://help.ubuntu.com/community/BIOSUpdate does it change anything?

If it doesn't, could you please both specify what happened, and provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

For more on BIOS updates and linux, please see

Please note your current BIOS is already in the Bug Description, so
posting this on the old BIOS would not be helpful. As well, you don't
have to create a new bug report.

Once the BIOS is updated, and the information above is provided, then
please mark this report Status Confirmed.

Thank you for your understanding.
