I have a custom image build from OpenWRT 18.06 and also have updated
ath10k driver and ath10k firmware to the latest master version. The
device is based on IPQ4019 and the image can be build using "QCA
AP-DK04.1-C1" target profile (with some modifications).
The device works O.K. and also the wireless is working. However, when
there are high number of stations connected to this AP, like over 60,
we are experiencing very unstable wireless connection. Looking at the
logs we see messages like:
ath10k_ahb a800000.wifi: failed to set beacon mode for vdev 0: -11
ath10k_ahb a800000.wifi: failed to set dtim period for vdev 0: -11
nl80211: wpa_driver_nl80211_event_receive->nl_recvmsgs failed: -5
WARNING: CPU: 3 PID: 9327 at
(Unfortunately I do not have the whole log, but I'll try to reproduce
It seems like that there was something wrong with the firmware, since
we were getting errors that the driver practically cannot set any of
the parameters. Those messages were for 5GHZ, on 2.4GHz everything
seemed to be normal.
We also tried with the ath10k-ct driver and we didn't see any errors
there. But there is a huge difference between the drivers, since
ath10k-ct only allows up to 32 devices to connect, while ath10k driver
allows up to 512 devices.
Any idea why?
Has anybody experience similar problems?
Is here the right place to report this problem, or should I report it elsewhere?
Thanks for any info.
