    I decided to try out a Sierra MC7455 WWAN module.
    Please note that I am in the habit of trying out WWAN modules for fun and assume the risk of non-Panasonic approved cards not working. Don't blame me if you try one out and it doesn't work out for you and you throw your money out the window in the process. To my knowledge Panasonic hasn't released any Toughbook with the MC7455.

    That said, the MC7455 is interesting because it supports many GSM and LTE bands as well as LTE Advanced which would make it ideal for traveling if it works.

    So I took the chance and bought one on eBay. Right away there were problems. It would suddenly disappear from the OS as if the device were pulled out of the slot and disabled itself consistently after a few minutes. When it was visible, it was almost impossible to connect. Looks like I fixed those issues.

    1) Downloaded Linux QMI drivers: https://source.sierrawireless.com/r...rivers-linux-qmi-software-s2,-d-,36n2,-d-,55/ (requires sign up to download). The file is tar.bz2 but in fact it is gzip. (tar -xzvf filename.tar.bz2)
    Then I cd into the extracted Gobinet directory. Ran 'make' then as root 'make install' or 'sudo make install'. Reboot and done

    2) Added usbcore.autosuspend=-1 to GRUB_CMDLINE_LINUX_DEFAULT section in /etc/default/grub, then as root update-grub or 'sudo update-grub' and reboot.

    Now I have a working MC7455 in a CF-31.

    YMMV

    Hey kode. I have a CF-31Mk3 that is running MX Linux 18.3. It has a MC7700 that I am going to try and get working. Will let you know how it went if things go well. If things do not go well, I will be looking for some help. :D L8R.

    On my 53, the wireless kept acting up so I de-activated network manager and installed CENI from synaptic manager.
    That might be another one to try if so inclined. This is on an installed Mx18.3 CF-53
    Wireless works good now at work.
    From Synaptic CENI is: "
    A Curses user interface for configuring network interfaces with ifupdown.
    Ceni can manage basic network interface ifupdown configuration stanzas for
    ethernet and wireless devices."

    Curious. What exactly was happening under Network Manager?

    Would not could not connect to the hospital WiFi network.
    For some odd reason CENI did the trick and didn’t play with it anymore.

    I have a no mouse issue with MX-18.3 on CF-31JCG802M
    Loading newest Peppermint and LMDE3 same issue of no mouse using the touchpad. Works in windows 7 hdd from the MK4 CF-31
    Searched and tried several fixes from links:
    https://forum.mxlinux.org/viewtopic.php?t=43690
    Ran this solution but nothing happens:
    demo@mx1:~
    $ sudo echo "options psmouse proto=imps" | sudo tee /etc/modprobe.d/psmouse.conf >/dev/null
    demo@mx1:~
    $

    http://forum.notebookreview.com/threads/linux-ubuntu-touch-pad-sound-fix-cf-31-mk2.813539/
    This link looks like it edits grub however in Terminal running the solution shows:
    demo@mx1:~
    $ sudo gedit /etc/default/grub
    sudo: gedit: command not found
    Edit...And am at a stand-still now asking for solutions....Edit
    Just found this old linkage and will try page 3: http://toughbooktalk.com/viewtopic.php?f=39&t=2662&start=50
    Followed Sheepman's directions for Terminal, and when I ran update-grub got this:
    $ sudo update-grub
    /usr/sbin/grub-probe: error: failed to get canonical path of `overlay'.
    demo@mx1:~
    $

    Simply shows that gedit isn't installed, which is Gnome's standard text editor. Try another editor. I think the default graphical text editor for MX Linux is leafpad.
    sudo leafpad /etc/default/grub

    Or try a text-based editor like nano or pico. Keep us updated!

    Nano works, ran this:
    sudo nano /etc/default/grub

    In the above, changed the grub line as described in toughbooktalk link, and then when I ran update-grub got this:
    $ sudo update-grub
    /usr/sbin/grub-probe: error: failed to get canonical path of `overlay'.
    demo@mx1:~

    So it doesn't look like grub was updated, and wondering what overlay means.
