This may not help much, but we have several users here in the U.K.
(Edinburgh, Scotland) using UK version 3 firmware who do not have this
bug.

You could probably mitigate some of the risks of providing a free/open
wireless service, if it was heavily restrictive on what ports were open
and if you used deep packet inspection to block common p-2-p ports and
service types. You would still potentially have an issue with traffic
going in and
Out of interest what level of transmission did you lower your APs to? I've
found changing transmit power has very little effect within a single
open-plan room, it only really seems to have much effect when the signal hits
obstacles such as walls, and shelves of books etc.
Many Thanks

We have a similar permanent requirement for this in one of our lecture halls.
Our solution has been 3 Access points, on 3 non-overlapping channels (channel
1,6 and 11). Each AP handles about 15-18 users at about 2 Meg near continuous
throughput per user on b/g if required. I looked at putting
channel, not AP/radio, that should
be designed to support a particular number of devices.

Matt, we are using both TKIP and AES on one SSID primarily for legacy
reasons. Our support documentation all says to use WPA2 and AES, but we
have left WPA- TKIP running for compliance with the eduroam

University's who still require
Garrett, we run with 15 minute lease times on the wireless network, the
only minor issue we came across was the default ARP table timeout was 30
minutes, which would normally be fine, so we needed to lower that on the
network switches to match.
Many Thanks

We implemented this for the start of this term. We have swung from 90%
web portal login and 10% 802.1x to about 60% 802.1x and 40% web portal.
The trend is still expanding as users use xpressconnect once and never
go back to web portal. User numbers in general have increased 300%
this term
I meant to also say our xpressconnect is at network-help.hw.ac.uk/xpressconnect

We've never needed to do it, but our access points draw power from
network switches and the switches have an API which can be used to
create stand alone applications which can interface with the switches.
With correct planning you can disable the Access Points in the lecture

We experience iPhones and iPod touches seeming to hold leases too long on a
regular basis, to the extent that I've seriously thought about dropping all the
Apple OUI's into a separate subnet from everyone else, I believe the network

We are EAP-PEAP compliant, and had gone down the route of documenting
setup instructions for as many os' as we could think of; including
phones, linux (top 5 distros each month), windows, mac etc. However
we found this wasn't sufficient to meet student's expectations for it
to just work,
I agree with Heath on this one, I would view a student transferring 1 TB of
data over our wireless network as being a non-technical issue and more one of
education that, that is an incredibly selfish action if done during peak times,
maybe a fair use policy is required?
That being said I have

Ryan, I've been working on something similar to what you've got set up
and I've a couple of questions about how you have set yours up, based on
some challenges I've had:
1. Have you had any issues with theft of wireless access points,
now that you are showing the coverage cells for
We run on half an hour lease times at Heriot-Watt University, Edinburgh
as well. I had the lease time set to 15 minutes for a while, but this
didn't seem to release IP addresses in any great numbers at peak times
when we most needed the leases available and just put more load on our
DHCP servers.
We too are seeing that MAC address in our logging for our wireless service,
although it doesn't look like there is an actual full user(s) log-in. It might
be pure chance that we have a device which should be using that MAC address but
I'm not convinced! So the issue may not just be limited to
If you have some lead laying around, you could line the rooms and turn the APs
off during lecture times... But as other respondents have said it's not really
a technology issue, you design your WIFI for full coverage for a reason.
Students use laptops to take notes like we all used to use
there. Instructors need to
manage the classroom, not take tools away, IMO.

We've looked at it before, the location accuracy is very good, but as I
mentioned before you will need to adjust radius reauth timers for it to work at
its best from my understanding for what is being talked about here. (plus we
didn't really need that level of location tracking, the Trapeze
I'm looking at it at the moment, and just trying to justify the cost of it and

Daniel, I would second what Lee said. I got a bit worried a few years ago on

Joe, it's not really a captive portal as such.
We've deployed it in two main ways:
1. Deployed onto a web server, with a link on our captive portal page, which is
accessible prior to login. This will then run Cloudpath's XpressConnect
