This has been discussed in the past, but it has been a long time.
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
We have axed 1, 2, and 5.5. But... in one case had to locally re-enable for
retail bar scanners, in another for ticket scanners, and just this week dealing
with Vernier Labquest2 scientific probes that will only work if lowest rates
are on.

We too were thinking of disabling the B rates. 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.

If you're using Cisco one thing to check is that the MCS0 data rate is enabled.

Hi Todd,
Disabling 802.11b is not an option but a must nowadays. You get much better
overall performance with all data traffic over OFDM.
There's a lot of time (Airtime)that gets lot if you allow old legacy protocols.
We have had 802.11b off for over a year and nobody complains.
Cheers

We've eliminated all the b rates on our wireless with no significant
issues. We had lots of connections to our wireless at 802.11b rates, but
it was users out of range from the APs, or clients with outdated drivers -
both problems which were easily corrected. Our wireless is entirely 1X,
so
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
That post belonged to me. You can still disable the 802.11b data rates (1, 2,
5.5, 11), which I have done at our campuses. You just need to leave the
802.11n MCS0 rate (6.5/7) in order to keep the iThingies happy.

We only disable 1 and 2 as we like to get all of the consumer wireless stuff
the students bring on campus connected to wireless. We use DHCP fingerprinting
to auth most of the stuff that can't do 802.1X or captive portal.

We disabled all the b speeds several years ago. Had no complaints then and
continue to not have any.

We will probably end most of the B rates at the end of this school year.
They have not been a problem since switching to Ruckus wireless. We get
a LOT of BYODs on campus, we support TVs, Game Consoles, wireless
printers, etc. Most of our slower B traffic has been Android devices.

In my experience, disabling b rates only help in areas with high AP density, in
particular, Apple devices that like to be very close to the APs. In areas with
low AP density, it could create issues for devices such as Macbooks.

Forgot to mention, if you run Aruba (and I'm sure many others support a similar
feature), you can check a flag called Broadcast/Multicast Optimization and even
when leaving b rates on, broadcast and multicast won't be sent at the lowest
basic rate, but the minimum supported rate by the stations
We turned off all B rates this summer along with 802.11b protection (we are
an Aruba campus). We did it during the summer and saw immediate improvements
in speed. To be effective, you need all B rates off, the goal isn't to kill
the lower speeds, the goal is to kill B altogether. It's an
We dropped 802.11b this time last year. I haven't received one complaint, and
the performance increase was dramatic. Your mileage may vary, but I found that
APs would go into b/g protection mode if they thought an 11b client might be
around. What resulted was a situation where about half of our
What about Nintendo Wii? We disabled 1 2 Mbps a couple of years ago and found
that Wiis could no longer connect. Found that they required 1Mbps. Maybe this
is no longer the case and I can back to turning it off.

I have also killed b data rates as well. The issue with the Wii is true
here is article describing the issue. We have had a few complaints in the
residence halls regarding the Wii. For those folks we just educate them to get
a wired lan adapter for their Wii system. The only place we had
FYI- Ticketmaster has a new Janam dual-band scanner that does nicely on 5 GHz
in my testing.

This is official, we have almost reached the capacity of our public IP
addresses (20,000 just on Wireless)
We love IPv6, but for the moment it's not going to solve our issue!
So, NAT it is, and we have zero experience besides our visitor network that
handles 1000+ users.
Our plan is to
When I disabled the lower rates it broke the wii. That was last year so
maybe the wii has improved. I re-enabled 1,2 and the wii started working.
