I'm looking to remove the low data rates 1Mbps and 2Mbps, but I'm confused about Basic Rates and Transmit Rates.
Right now these rates are checked:
802.11g Basic Rates: 1,2
802.11g Transmit Rates: All
If I want to remove 1 and 2 Mbps, I assume that I need to uncheck those rates for both Basic and Transmit?
Also, is there any reason not to have all rates 5 and above checked for both Basic and Transmit?
Solved! Go to Solution.

Thanks for the info.
Does that apply to a as well?
I currently have 6,12, and 24 selected as 802.11a Basic Rates, and all 802.11a Transmit rates selected.
I believe this was the default, as I haven't poked around in these settings before.

Sorry, I'm not sure I understand. When you said "Correct" did you mean that my 'a' config was correct?
Also, no b supported here. What data rates do you recommend for a college campus?

Sorry. Correct as in the same logic is used for the 11a radio.
It's best to test the data rates in a building for a week or so to see if any issues are being reported.
This is a great tool to help you determine data rates for your environment:

Thanks for the info.
One more question: To turn of b mode, do I simply disable 1,2,5.5, and 11Mbps?
Or is there something else I need to do?
Or can I leave those low rates for g to use in DSSS mode? (not that I necessarily want to, but just curious)
(actually, now that I think about it, g in DSSS mode is probably the exact same thing as b, isn't it?)

Your logic is correct. But in reality there is no 11 (1,2), 11b (5.5, 11), 11g (6-54) anymore. Think of it is that specific amendment introduced that rate. The rates still exist but are all the amendments are wrapped up in the latest 802.11 standard. So all are with the standard.
Your are correct that the rates are based on the modulation schemes. I'd agree to remove 1,2,5.5,11, and while you are at it 6 and 9.

I checked with Aruba TAC and they said to leave the Basic Rates set at 1 and 2, even if the lowest transmit rate was set to 12.
Tim's suggestion (two lowest transmit rates are used as the basic rates) seems to make more sense.
