Run

Code: Select all
# dmesg


in a terminal and look for error messages about the wifi card in red: you need to install the firmware at a guess.

Freewheeling Frank, I rang the command you listed and got following that was all in "red", but I must admit I am not sure of what I need to do to repair the problem?

Have you installed the firmware (driver)?

Have you rebooted?

But can you do a google search?

Connect TEMPORARILY by cable.

Issue this command
Code: Select all
sudo apt install firmware-iwlwifi


It will ask for the password, then let it run.

When it has finished, remove the cable and reboot.

Your wifi should be working.

Besides firmware-iwlwifi, note that your AMD graphics card is also complaining about missing firmware--that package is "firmware-amd-graphics". If you can't wrangle a wired connection, you can also download the packages from packages.debian.org on a connected machine/OS, transfer them to the isolated Debian machine, and install them with "dpkg -i <debfile>" as root or with sudo.
The MX Linux repositories: Backports galore! If we don't have something, just ask and we'll try--we like challenges. New packages: Flightgear 2018.2.2, 4.19.5 kernel, wine-staging 4.0~rc1, Pale Moon 28.2.2, Mesa 18.2.6, Midori 7.0

Well, thar's been answered, but I'll make a few points.

The items in red are error reports.

The first seems to be for a BIOS error, by the way. You may need to update your BIOS- but that's another kettle of fish.

The firmware errors are for missing firmware packages or componemts of those packages. If you search for the error messages you will come up with links to the firmware package.

rtl_nic/rt18106-1.fw for example brings up the realtek package although the listed component doesn't quite match.

"...failed to laod" looks like a typo- did you copy these by hand? Always better to cut' n paste if you can.

From the links provided you will have learnt (I hope) that you need to edit the sorces file to include non-free software before you can install firmware-iwlwifi and firmware-amd-graphics and firmware-realtek.

To help you with that, you can look at a list generator like this one- it will show you what your sources file should look like (You can't leave source [code] unticked.)

https://debgen.xyz/

There are lots of tutorials on the net about how to edit a root file in Debian. Of course some are less clear than others. This seems OK (although it's a rival forum :oops: )

http://www.debianuserforums.org/viewtopic.php?t=388

You will need to install gksu (or KDE equivalent) if you want to use a graphical interface (from memory).
