Axios Thanks for your suggestion.
After I installed it, I ran the suggested command. Some details flashed up on the screen too fast to read and then it just jumped down a line waiting for the next command without displaying any information.
Maybe I should try installing the GitHub drivers again, do a reboot and scan again.
- Edited
(sudo lshw -C network) Nothing fancy about that command its saying it doesnt like something
if you got enuf screen should just display.
Guess it doesnt like something we knew that thought it would help us out abit.
You got secure boot turned off right I dont think it will load that wifi with it turned on?
Axios I installed the GitHub driver and rebooted. Can see networks but security password will not accept. When I shut down the tablet it hung. I will take a more detailed look at that later.
Also took another try with sudo lshw -C network and now have an output. I will post that up later as I don't have access to my computer right now.
Axios Somewhat later...
Tried tablet again, startup and shutdown are both fine. Results of sudo lshw -C network with GitHub drivers installed.

BuzzPCSOS It would appear to me that driver is loaded and working but it is not
the right one. (Everything you replied to is proper)
I have seen two others but havent researched them enough yet found one post the guy could not login
but changed the driver and then it worked (not sure if that was to the wifi not working at all or if was just login i Got the impression it was login) that was a manjaro forum I think.
I think it has something to do with the wrong 802.11 mode. (Not 100% sure)
To pooped tonight to research seen yer post on manjaro
- Edited
BuzzPCSOS Run this and see what it spits out so maybe we can nail down driver.
(lspci -nn -d 14e4
Note; going ramble for a minute
I was checking out my budgie in the BRCM firmware directory Solus does have those files that you installed
on manjaro so the question is why did solus not work then?
But there are many for different devices like this and then what appears to be a generic blob.
So whats different between those files I have no idea at this point.
My point was if manjaro with the generic blob is at least seeing your wifi why didnt solus.
(Is Solus smarter?) inquiring minds want to know..
If what I see is correct
Busy today will tinker later..
Axios 
I think part of the lspci -nn -d 14e4 command got confused as an emoji. Unfortunately I don't know what I am supposed to be doing so couldn't just make a good guess.
Some of the problems with these drivers is that they are motherboard specific also there are both sdio chips and pcie chips which can make detection and usage of a universal driver a bit hit and miss.
I have the driver that worked on Windows so I might be able to determine from that what Linux driver I should be looking for. On one Ubuntu forum there was even the suggestion that the Windows driver instruction file could be renamed and used to enable the built in Linux drivers.
Food for thought.
Right at the moment I don't have a physical keyboard for my linx12 so things like renaming files and other simple tasks are a pita and have restricted what I can do to test out new drivers. If I can get the WiFi working in the end I will most likely record what was needed to make it work and then wipe and clean install, I have chopped everything around so much already that it is a wonder that it still boots.
Axios Oh right, well it just complained when I tried that.
lspci: -d: At least two fields must be given
I have done a bit of reverse engineering and have the build revision of the driver that worked on the tablet with Windows on it.
802.11ac WDI SDIO Adapter
Version: 1.596.13.0
Date: 25 July 2016
Size: 3.5 MB
INF file: bcmwdidhdsdio.inf
I wonder if it could be used to determine what Linux driver is required.

BuzzPCSOS Just use lspci am looking for the
line on your wireless as to what it says.
Mine looks like this
02:00.0 Network controller [0280]: Intel Corporation Wireless 8260 [8086:24f3] (rev 42)
Yours might look something like this or along those lines
Broadcom Corporation BCM4306 802.11bgn Wireless Network Adapter [14e4:4320] (rev 03)
Did you do anything with the nvram.txt file when you installed the drivers (not sure of the exact nvram name)
lspci ξ²

Tried the text file without any luck. On windows it required a specific driver and a specific .txt file to be manually loaded. It wouldn't work with a later or an earlier driver as far as my efforts showed.
Might need to admit defeat here and just use an external wireless adapter, that way I don't need to worry about loosing my WiFi every time there is an update.
- Edited
BuzzPCSOS Its not showing your wifi
Thats the way i saw it in my mind the way you explained (I have the windows stuff been analyzing and looking
through those files to)
I dont know how the heck on linux one would know the two proper files to have the reason I say that
is was reading them from solus and they each vary to some degree not all the same.
But thats prob where the issue is its gotta have both proper files/version.(Just not having much luck putting the two together)
I ran across this and tried it gives ton of info (it ask for root to gather info but no worries there)
might be handy.

Sorry I dont have a solution will keep an eye out.

Edit. Original removed as too much redundant information.
Wireless grab after boot with internal wireless device only.
