Help troubleshooting wireless on Baytrail....

I've got a Dell Venue 8 Pro that I'm trying to run Arch on.  I've got Arch installed, and I'm 90% of the way to where I want it, if I could just get wifi to work...

What I've Done:

  1. Downloaded the proper firmware for the wifi device from here.  Copied firmware to /lib/firmware/ath6k.

  2. Downloaded kernel source for version 4.4.8.  I've also tried 4.5.2, but I've had more success with 4.4.8.

  3. Patched kernel source to include proper device id for this wifi device (Source.

  4. Enabled ATH6KL and ATH6KL_SDIO in the kernel (I've also enabled ATH6KL Debugging and Tracing as well as a bunch of GPIO and I2C stuff relevant to Baytrail as outlined here)

  5. Comiled and installed kernel.  Installed modules.  Built new ramdisk. Updated GRUB config.

Kernel boots fine.  ath6kl_core and ath6kl_sdio modules are loaded at boot.  wlan0 device exists after boot.  ip link output:

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: wlan0: <BROADCAST,MULTICAST> mtu 1500 qdisc fq_codel state DOWN mode DEFAULT group default qlen 1000
    link/ether 88:12:4e:04:e8:c2 brd ff:ff:ff:ff:ff:ff

I generally use netctl to manage my wireless.  wifi-menu successfully scans and lists my wireless networks.  When I try to connect though, it always fails.

systemctl status:

The interesting thing to me is the kernel messages that wlan is disabled.  If it was disabled, would I be able to scan for networks?  If it is disabled, how do I enable it?  I've got all ATH6KL entries in the kernel config enabled.

I have an RTL8192 USB wifi dongle, and when I use that, wifi works just fine, so it isn't something inherently wrong with my Arch install.

I have no idea what my next steps should be to troubleshoot this.  Any help would be greatly appreciated.

Re: Help troubleshooting wireless on Baytrail....

What happens if you try and connect manually?

Right!  I knew I forgot something in my post.

Interesting.  I just worked through the wiki, and turned something up.  Whenever I've tried manually in the past, I haven't bothered to scan - wifi-menu has already shown me scanning works.  Then, I've always daemonized wpa_supplicant with the -B flag, which always returned "Successfully initialized wpa_supplicant", but then dhcpcd would time out.

Today, I followed the wiki exactly.  iw dev wlan0 scan appears to just hang.  It doesn't return any results.  If iw dev wlan0 scan isn't working, how does wifi-menu succesfully get a list of wireless networks?

Re: Help troubleshooting wireless on Baytrail....

Try it with the debug flag; that might provide some clues.

Re: Help troubleshooting wireless on Baytrail....

Here is the output of iw scan with --debug enabled.  It's long, and I can't make heads nor tails of it.  It was tricky to get the output becuase iw scan doesn't exit.  it hangs at the end of the output shown.

Re: Help troubleshooting wireless on Baytrail....

I tried going back to Kernel 4.5.2, because it actually has some specific baytrail stuff in it that doesn't exist in 4.4.  When I patch for the correct device id, and enable the required stuff for the baytrail, the wireless device isn't recognized at all.  ip link doesn't list a wireless device.  modprobe'ing the ath6kl modules does nothing.  There's no errors, but still no device.

I'm not exaclty a newbie to Linux, but this kind of stuff is pretty far from my comfort zone.

Re: Help troubleshooting wireless on Baytrail....

I noticed today that with my custom 4.4.8 kernel, my RTL8192 based dongle doesn't work.  I built a new 4.4.8 kernel to include the RTL8192 support.  With my new kernel, nothing has changed with the internal wifi.  I can connect the RTL8192 dongle to wifi without issue.  I get all of the same behaviour outlined above with the internal wifi still.
