Sorry for the late = response, although I can see from yesterday's
SmokePing = plots that the issue still prevails.

1.
You should definitely not allow rates as low as 1Mb/s = considering:
* plots of signal vs. rate,
* = topology of closely packed cabins;
* mostly static, = noise-free camp ground.

Almost all of your = clients were able to link with >20Mb/s even at
70-80dBm. = Those below were probably just idling. I'd limit the network
to 802.11g/n-only, and would even consider disabling all = rates below
12Mb/s.

I have been wanting = to do this on my APs for Scale (wndr3800 APs with ath9k chipsets) and = have been unable to find how to do this on these chipsets.

I also didn=E2=80=99t manage to disable = specific MCS rates:
- supported_rates = and basic_rate in /etc/config/wireless seem to only affect legacy = rates, not ht-mcs-2.4 rates.
- "iw dev wlan0 set = bitrates=E2=80=9D only sets the transmit rate for the AP

But what I did do at = 10:45am today, June 8, was disable 802.11b rates with:

uci set = wireless.radio0.legacy_rates=3D=E2=80=980'
uci = commit
reboot

So at least the minimum rate should be = limited to 6Mbit. We=E2=80=99ll see if this helps in the next few days = as the camp fills, and if I hear any complaints:
