Hello,
sometimes my AP simply stops working.
Typical situation:
- (me coming home from work)
- client (Nexus 5, Xperia Z3 Compact or another ath10k device) can see
my ath10k AP for a brief moment
- AP is gone, errors from below show up in the kernel log
- reboot of my AP is required to fix this
[54064.293597] ath10k_pci 0000:02:00.0: failed to install key for vdev
0 peer [AP MAC addr]: -145
[54064.301234] wlan0: failed to remove key (1, ff:ff:ff:ff:ff:ff) from
hardware (-145)
[54067.305703] ath10k_pci 0000:02:00.0: failed to install key for vdev
0 peer [AP MAC addr]: -145
[54067.313307] wlan0: failed to set key (1, ff:ff:ff:ff:ff:ff) to
hardware (-145)
Some OpenWrt and LEDE users are reporting the same problem: [1]
my AP is a (Lantiq VRX268) MIPS based device running a recent version
of LEDE and I am using ath10k firmware version 10.2.4.70.54. I
attached a part of my boot log at the end of this email in case more
details are needed.
What should I (or any other user who experiences this) do whenever
this happens to help you track down the issue?
Also please let us know if there is anything else you need to know
about the affected systems.
Regards,
Martin
