[Cerowrt-devel] ath10k woes

[Richard Smith]

Based on some of the traffic I've seen on this list I've been trying to 
get an Archer c7v2 running Chaos Calmer up and running where I work.  It 
mostly works but I'm having reports of lots of disconnects from 
stations.  In the logs I see loads of messages like the following:

Tue Apr 21 09:33:15 2015 daemon.info hostapd: wlan0: STA 
bc:c6:db:6d:c7:d2 IEEE 802.11: disconnected due to excessive missing ACKs

Google seems to suggest that the following option may help:

  option disassoc_low_ack '0'

But I don't see much change after I've added it.

I also see a lot of the following messages:

Any ideas?

I'll add that many of the exact same stations when connected to a 
wndr3700v2 running barrier breaker do not have these same problems.
