Do you have eeprom_ar6320_3p0_SS_720.bin on your Windows partition; in other words, not the K variant? If so, please transfer it, too and let's experiment.

On the assumption that you do, please back up the current board.bin:

sudo mv /lib/firmware/ath10k/QCA6174/hw3.0/board.bin /lib/firmware/ath10k/QCA6174/hw3.0/board.Kbak

Next, we try the non-K version:

cd ~/Desktop
sudo cp eeprom_ar6320_3p0_SS_720.bin board.bin

And copy it to the firmware library:

sudo cp board.bin  /lib/firmware/ath10k/QCA6174/hw3.0/

Check:

ls -al /lib/firmware/ath10k/QCA6174/hw3.0/

You should have, among others, a board.bak, boardK.bak and a new board.bin.

I am interested in the differences, if any:

cd /lib/firmware/ath10k/QCA6174/hw3.0
md5sum *

You know the rest.

[makem2]

Note that the bin files I obtained from windows are both 620, not 720 as your instructions gave. I have used the 620 non K bin file:

Note that the bin files I obtained from windows are both 620, not 720 as your instructions gave. I have used the 620 non K bin file:

Your post #6 suggests 720. Are there both 620 and 620_K and 720 and 720_K files available?

I am quickly running out of ideas, mojo, ammo.

[makem2]

I have searched for the eeprom_ar6320_3p0_SS_720.bin file in widows to be sure and it does not exist.

Reading the thread you mentioned:

https://patchwork.kernel.org/patch/9951857/

I see that his machine is identical to mine except for the RAM amount and maybe SSD size. I would think the 'internals' would be otherwise identical.

[makem2]

Your post #6 suggests 720. Are there both 620 and 620_K and 720 and 720_K files available?

I am quickly running out of ideas, mojo, ammo.

Extract from my post #6:

EDIT: For clarity the file names are:

eeprom_ar6320_3p0_SS_620.bin

eeprom_ar6320_3p0_SS_720_K.bin

You asked that I tried the K file and I did so. You then asked that I try the non K file which as shown above is 620.

I tried eeprom_ar6320_3p0_SS_620.bin

Sorry if I am wrong somewhere.

Edit: I found that above I wrongly referred to BOTH files being 620, sorry. I hope the explanation above resolves the confusion.

[chili555]

Please note that his dmesg said:

failed to fetch board data for bus=pci,vendor=168c,device=003e,subsystem-vendor=144d,subsystem-device=c14f,variant=K from ath10k/QCA6174/hw3.0/board-2.bin

But yours says:

failed to fetch board data for bus=pci,vendor=168c,device=003e,subsystem-vendor=144d,subsystem-device=c14f from ath10k/QCA6174/hw3.0/board-2.bin

In other words, no Variant K.

The referenced link suggests editing the code for drivers/net/wireless/ath/regd_common.h to add the missing regulatory domain/country code 0x5f. I have no suggestions as to how to accomplish this.

I do note that the latest kernel versions, 4.15.2 does not contain the patch: https://elixir.free-electrons.com/li.../regd_common.h Therefore, I assume that installing a newer mainline kernel version would be ineffective.

I am now wondering if we can edit the board.bin file. Studying...

[jeremy31]

I added the patch to backports so we can try

sudo apt install git build-essential
git clone https://github.com/jeremyb31/backports-4.14.git
cd backports-4.14
make defconfig-wifi
make
sudo make install

Reboot

After kernel updates you will have issues until you

cd backports-4.14
make clean
make defconfig-wifi
make
sudo make install

Reboot

[makem2]

All completed without apparent error except I did notice:

cc -Wall -Wmissing prototypes etc.

I do have the full output if needed.

However, crossing fingers and toes had no effect I am afraid. I am typing this on another linux machine because the tablet no longer has WiFi access with or without the dongle.

I can do a dmesg | grep ath and transfer it here?
