Hello,

Lower rates and transitions= between rates were things I didn't think of
before.

Somethin= g worth a shot is to set DSCP to 0 for all packets which go
out on wlan= 0 to see if this has any impact on those spikes:
iptables -t mangle -A P= OSTROUTING -o wlan0 -j DSCP --set-dscp 0

The rule didn't seem to= work at all for me. No packets were matching
this.

The C7 has an older version of firmware. It would be interesting to
