I've been able to get channel utilization below 20% after modifying the 802.11g basic & transmit rates. I followed TAC's top 10 tips for clipping lower data rates, but realized after implementing the changes that they're meant for VoWiFi devices.
Here is what is suggested and what was implemented:
g-basic-rates 5 6
g-tx-rates 5 6 9 11 12 18 24 36 48 54
I assumed this removed 802.11b rates, but I'm not sure that's the case. Can someone please let me know the proper basic rate and tx rate values should be set to effectively remove 802.11b capabilities?
Also, I'd like to mention that I noticed frame check sequence errors go up on 2.4 after I made the rate changes.
