Just to make sure we have as much information here as we can for everyone to inspect, let's post the results of lsusb and lsmod.

Another option for your consideration, but we may want to wait & see what others suggest first, is to apply the latest Level 4 & 5 updates, but that's not my recommendation, so let's save that as a last resort. Given that you were already compiling new kernels, you seemed like the adventurous sort, so it came to mind, but again, I would recommend seeing what others have to say first. I tend to be cautious with other people's computers, but far less so with my own.

[slasherx2]

Haha, yes adventurous describes me well! I'm not too fussed if it messes it up, it's a fresh OS and I have nothing really on it. I have applied the level 4 & 5 updates already actually as well. If i need to revert back to a fresh install now before trying anything else. that can be done.

Here are the lsusb and lsmod outputs.

I am happy to try pretty much anything with this because as I say, I can always revert back to mint default.

[slasherx2]

Boot into Windows and go to the device manager, find the wireless card, double click on it. Then choose the "details" tab and use the dropdown menu to find hardware id's and post the info

Give me a few minutes and I'll do that now.

[slasherx2]

Hardware IDs from Windows

Code: Select all

SD\VID_0271&PID_0419
SD\VID_0271&PID_0419

[JeremyB]

Since you are using the 4.10 kernel you may want to register at https://bugzilla.kernel.org/ and file a bug report, describe the issue as wireless not found with the hardware ID's from windows

Also show me result for

Code: Select all

ls /lib/modules/

I might be able to patch kernel source code to support this device as I have seen a patch to support a device in the Venue 8
http://git.kernel.org/cgit/linux/kernel ... b0f92d0533

I think the patch for yours would include

Code: Select all

+	{SDIO_DEVICE(MANUFACTURER_CODE, (MANUFACTURER_ID_AR6004_BASE | 0x19))},

[slasherx2]

Hi,

I did try to apply that patch myself and recompiled the kernel and installed the deb file and rebooted, but I am not sure if I did it right.

I also noticed that I lose my touch screen support on the newer kernel which isn't ideal.

I'll reboot and the result of the /lib/modules.. which kernel should I do that on?

[JeremyB]

It doesn't matter what kernel you use for

Code: Select all

ls /lib/modules

It will tell me what kernels you have installed. For a change like the one I proposed, I would just build the one module rather than the entire kernel

[slasherx2]

I didn't actually know how to patch it in on the fly, hence recompiling the kernel. I was going to bed at the time anyway so it wasn't a huge deal waiting.

Anyway, here' the output from that command

Code: Select all

craig@craig-Venue-11-Pro-7130 ~ $ ls /lib/modules
4.10.1                 4.10.1-041001-lowlatency  4.4.0-64-generic
4.10.1-041001-generic  4.4.0-53-generic

[JeremyB]

ath6kl_sdio.ko.tar.gz

Download and right click, extract here. It should be in the Downloads folder, so in terminal

Code: Select all

cd Downloads
sudo cp ath6kl_sdio.ko /lib/modules/4.4.0-53-generic/kernel/drivers/net/wireless/ath/ath6kl/ath6kl_sdio.ko

Reboot and use the grub menu to boot into the 4.4.0-53 kernel and then run

Code: Select all

sudo depmod -a

Reboot again into the 4.4.0-53 kernel and see if it works

[slasherx2]

No go unfortunately. Had a look at Ndiswrapper and that still says hardware not present and nothing shows in driver manager either

[JeremyB]

You had ndiswrapper installed with the windows driver? That would poison the results as ndiswrapper has it's own file in /etc/modprobe.d. Please purge ndiswrapper and reboot.

I did a modinfo check on the module I attached and it should work

Code: Select all

alias:          sdio:c*v0271d0419*
alias:          sdio:c*v0271d0402*
alias:          sdio:c*v0271d0401*
alias:          sdio:c*v0271d0400*
alias:          sdio:c*v0271d0301*
alias:          sdio:c*v0271d0300*

As I think sdio:c*v0271d0419* is the linux equivalent of SD\VID_0271&PID_0419

Ignore Driver manager as it is just for proprietary modules from Broadcom for their wireless cards and some AMD or NVidia video cards. Atheros modules will never show there as they are open source

[slasherx2]

Got you. My apologies. I shall give that a go tomorrow and report back. It's 11.40pm here and I'm up early.

Thanks for the help!

[JeremyB]

Not a problem, I just hope it works. I am not a fan of ndiswrapper as results are usually poor when it does work

[slasherx2]

Still no go unfortunately. Maybe I should try wiping and installing a fresh copy of Mint then patching with your patch?
