We removed 802.11b data rates on our campus in 2011. We didn't hear any
feedback directly or by way of our Helpdesk. At the time we turned those
rates off, 802.11b clients were a negligible percentage of our wireless
users (rounded to ~0.0% when we put together our usage stats for that year).
We're also seeing a 50-50 split as far as associations go, but for
actual usage (based on data transferred), things do look a bit more
promising.
Associations:
- 51% @ 5GHz (32% .11n, 17% .11ac, 2% .11a)
- 49% @ 2.4GHz (36% .11n, 13% .11g)
Usage (Data Transferred):
- 66% @ 5GHz (34% .11n, 32%

day" for us. (Tuesdays are usually our busiest day of the week,
network-activity-wise.)

We do the same on a pair of the A10 AX3530's, and it's been working very
well for us. We are currently NAT'ing a /12 of internal addresses into a
/16 of external addresses (~4000 ports per internal IP). When doing
lookups, we just pre-generate a lookup table of the outside IP port to

At 2.4Ghz, our minimum data rate and beaconing rate is 12Mbps. At 5GHz,
it is 6Mbps.We have our beacon interval set at 100ms.
In 2008, we shut off everything below 5.5Mbps (at 2.4Ghz) in 2008. In
2011, we shut off everything below 12Mbps, which how it is still set today.

I'm curious which CA's you are using for your RADIUS servers for your
802.1x implementations.
We are looking to renew our cert (coming up on expiration), which is
signed by one of the Thawte CA's that is being deprecated. At the time
we selected that CA because it was widely supported
We didn't see as sharp of an increase for this, but overall traffic
reached about the same level for us on iOS 8 as it did last year for iOS 7.
This is what we saw for iOS 8:
ios8_20140917
And this is what we saw for iOS 7 last year:
ios7_20130918

We have a couple of different ways we accommodate guests.
First, we have a contract with ATT to provide our guest/visitor
network. We advertise an attwifi SSID on all our AP's (minus a couple
of specific locations), and that network gets dropped off on an ATT
circuit. The attwifi network is
We saw similar symptoms in the past. Our setup was a bit different though.
What it came down to for us was that the EAP conversation would start on
one backend RADIUS server, but it would jump to a different backend
server part way through. The backend servers didn't share state, so when
the
We stayed off the UNII-2e channels for a while due to client
incompatibility as well. We lit them up this past summer (August 2013)
across our entire campus, and so far, we haven't seen any specific
problems stemming from it. We had enabled UNII-2e channels in some areas
prior due to the need
We are using the A10 AX3530 platform to do NAT for our wireless network.
We use fixed NAT to avoid having to track by individual
connections/sessions. It's just a static mapping of internal address to
external address + port range. Then it's just a matter of tracking the
internal addresses to
We peaked at just over 9.5Gbps today on our campus (30 second averages).

We do not have a separate pipe for wireless traffic. Wireless accounts
for ~55-60% of the overall Internet usage for our campus.
We track consumption per user and have an automatic penalty box type

This was done after some trail-and-error testing. Originally, we had it
