clean install, wifi device isn't detected on Linx 12x64 tablet, need a driver?

Hello Monjaro community!

I am having a bit of trouble trying to get wifi working on my Linx 12x65 tablet. I have wiped windows from it and done a clean installation of the latest version of Monjaro.

This is the tablet I have:

As you can see from that link there is a wifi driver that needs installing, but this is only for windows 10. Is there anyway I could get this working on Monjaro?

I've had a look through many other threads with a similar issue but none of them helped me out.
Here are some commands I ran that seemed to help diagnose the problem for other people.

$ rfkill list all

~ >>> rfkill list all

Thanks for your reply bogdancovaciu,

So I followed the instructions which were, put Arch linux on a USB stick (in this case its Monjaro). Proceed with an install as normal. I have already done this (but with Monjaro).

Copied the gitHub files to my USB.
It says for me to add 4345r6nvram.txt to brcmfmac43455-sdio.txt, but brcmfmac43455-sdio**.txt** does not exist. So what I did was just copy 4345r6nvram.txt and rename it to brcmfmac43455-sdio.txt.

However there is a file called brcmfmac43455-sdio**.bat** though??

Even then I cant restart the driver by using:
modprobe -r brcmfmac && modprobe brcmfmac
because I get the error "modprobe: ERROR: could not insert 'brcmfmac': Operation is not permitted."
The internet says that its because of secure boot being on, but I've checked, its disabled.

Anything I'm missing?



Well, that how to should be formatted better, but here is what is saying and what i understand from it; from inside that files folder run:

sudo cp 4345r6nvram.txt /lib/firmware/brcm/brcmfmac43455-sdio.txt
sudo cp brcmfmac43455-sdio.clm_blob /lib/firmware/brcm/brcmfmac43455-sdio.clm_blob
sudo cp BCM4345C0_003.001.025.0110.0169.hcd /lib/firmware/brcm/BCM43455C0.hcd

then to start the driver run

sudo modprobe -r brcmfmac && sudo modprobe brcmfmac

you should have wireless at this point

For sensors related to screen rotation you run:
sudo cp 61-sensor-local.hwdb /etc/udev/hwdb.d/61-sensor-local.hwdb
and probably will work next reboot.

I honestly don't know anything about BCM4345C0_003.001.025.0110.0169.hcd file tho ...


Thank you so much for your support. Works perfectly now! :slight_smile:

Hey @bogdancovaciu,

I hope you don't mind but I made a YouTube video to help people out with this issue. I gave you some thanks in the video at 13:10 !

Thanks again,



Glad is working, and if your video will help others too, even better. Thank you too for the shout-out :smiley:
