[Bug 1525228] Re: Qualcomm Atheros QCA61x4 cannot connect to encrypted 5Ghz networks


Roman, thanks for testing. The next thing that would be helpful is the
WAP manufacturer, model, and firmware version. It is understood that
this is primarily reproducible with a university WAP. However, given the
circumstances, it would be proper if you asked them for this
information, and for them to provide it to you so you may get your
device working on campus.

Hence, could you please advise to this?

  Qualcomm Atheros QCA61x4 cannot connect to encrypted 5Ghz networks

Status in linux-firmware package in Ubuntu:

Bug description:
  The device works fine with Ubuntu 15.10 mainline kernel 4.2.0 and the
  firmware provided in linux-firmware on 2,4 Ghz wifi networks or
  unencrypted 5GHz networks.

  But when i connect to a encrypted 5Ghz network.  The firmware provide in linux-firmware (WLAN.RM.1.1-00141) crashed like i think is described here:

  So i installed the latest firmware release
  SW_RM.1.1.1-00157-QCARMSWPZ-1 from ath10k-firmware

  In this version the firmware doesn't crash but goes into a loop. Like
  you see in dmesg, the device associates with the AP, but from an
  unknown reason it cannot connect.

  At the moment i cannot provide you any details about the AP im testing
  with, because im using my universities network, but if you really need
  them i can test the device with an known AP in a week or so.

  I reported the bug to the ath10k mailing list, but i think the topic got lost:

  PS: I tested the problem with all mainline and upstream kernels(4.2.6,
  4.3.0,4.4rc4) without any difference.
