I also didn’t 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” 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=‘0'
So at least the minimum rate should be limited to 6Mbit. We’ll see if this helps in the next few days as the camp fills, and if I hear any complaints:
