We've disabled 1,2 and 5.5 rates but left everything else on (inc. 6 and 9 Mbps on g and 7 Mbps (MCS 0) on n).
Working fine for us so far. 44 Buildings (inc. Halls of Residence and campus in Cyprus), 1000 Cisco APs, 3500 peak users/devices, 8000 unique users/devices per day, 1 TB traffic per day.

But I read (post below) that some people run into Apple devices dropping connection when they did this so I am still looking at this. Post: If you're using Cisco one thing to check is that the MCS0 data rate is enabled. I had a lot of problems with Macs and iThings dropping after I disabled the 802.11b rates and MCS0. Per TAC's suggestion I re-enabled the MCS0 rate and have not been experiencing the problems since. Apparently it has to do with the OS dropping the data rate to MCS0 to save power, but not checking if that rate is supported before doing it.

We're at the point that we have to turn off the lower connection rates on our campus. I'm curious what other schools have done and the positive/negative results from the changes. We have disabled 1, 2, 5.5, and 11 Mbps in some of our buildings with great success, but some might argue to just eliminate 1 & 2 Mbps rates. Also, I'd be interested to hear from schools that have not disabled these rates and why not. -- Todd M.
