Hi all,
I am using:
ath10k-firmware-qca9984 - 2018-12-16-211de167-1
kmod-ath10k - 4.14.109+4.19.23-1-5
## Problem
I am able to associate and authenticate many clients. Max I tested was
15 clients.
But when more than 4 clients start to play video stream (youtube,
twitch, netflix):
1. all the clients loose internet connectivity
2. all of them are _de-authenticated_
3. when trying to reconnect, they connect but are _disassociated_ immediately.

RX: 12.0 MBit/s 17 Pkts.
TX: 12.0 MBit/s 5 Pkts.

4. internet on the AP works. (I am able to ping google.com)
## Firmware and OS this problem occurs
- ath10k + 18.06.2 = yes, there is this problem
- ath10k + snapshot = yes, there is this problem
- ath10k-ct + 18.06.2 = yes, similar problem occurs
(https://github.com/greearb/ath10k-ct/issues/82)
- ath10k-ct + snapshot = no, works fine

### More logs
I noticed that the some devices stay connected :man_shrugging: and
when these connected devices make a dns request, the request is
reaching the DNS server but the AP is not receiving response.
I ran ping on *one device* and captured packets on AP (two interfaces):
- tcpdump -i wlan0-ap
- tcpdump -i br-lan
ping google.com:
https://gist.github.com/ironpillow/50cb0e2010ac5bc9acc7abc7e20ab910
ping 8.8.8.8:
https://gist.github.com/ironpillow/97cb3dd6eb8e9d028a8231f142fae01f
Packets are not reaching wifi wlan0-ap interface.
I am happy to run more tests.
Any advice?
