sorry my bad
Your particular USB wifi requires a driver that is not included in the kernel.
Now the file that I have attached should be the one required to get the on board wifi going. There are some weird characters at the beginning of the text file that cause trouble when opening in a text editor.
Open a terminal and change directory to where you downloaded the file and runReboot
And tryAnd post the dmesg.txt
dmesg | grep brcm > dmesg.txtYour particular USB wifi requires a driver that is not included in the kernel.

Empty file ?
Hmmm that's strange by all accounts their should be a kernel message regarding loading the drivers.
you should have something along these lines
Ok OK My bad, one thing I didn't notice is that kernel has to have support for B43_SDIO which in needed for the on board wifi card.
I thought that the because the drivers were built this would be included.
So my friend it looks like I will need to rebuild the kernel and package it up for you. Or build a new ISO image.

Dmesg does not output anything without using sudo on all new-ish Linux distros.

Just booted up the H2 iso I created, dmesg works fine without sudo. Which was the ISO the OP installed from.

Is that with a standard kernel, debian rt or my rt kernel.
hmmm maybe I changed the dmesg permission
But this means I must have done it on ALL Mint installations on ALL machines, even those that have multiple versions of Mint.
Ok it's not that, I deleted /bin/dmesg then reinstalled util-linux (package for dmesg) & permissions were the same.
OK Dave you may have to run the dmesg command with sudo in front of it.
Hey Tommy just for interest can you run:If you get something other than 0 can you try,
Then try dmesg without sudo
To go back to previous, ie sudo requires dmesg
OK found out that there is a kernel config option that changes the operation of dmesg, to do with wether a user can read log.
The kernel I built, taken the default config from a std Mint kernel, allows a normal user to use dmesg without using sudo, the debian RT kernel does not allow this behaviour.

Some info on the picture above, there are all the lines run and the version of kernel, all this is on Linux Mint 19.3 with all the latest updates, and sure enough the kernel is from the Debian Stretch repository.
As can be seen above, the line proposed by Beagle does it's magic and now dmesg works with no sudo privileges.
Thank you Beagle.

Not too sure if that with survive a reboot.
Although we haven’t sorted dave’s Issue we’ve learnt something.
Sorry about going off topic.
