Tim,
In regards to your open SSID, how do you sway everyone from just jumping on that instead of using eduroam? Do you worry at all about someone sniffing the wireless traffic and getting someone else’s MAC address and then changing theirs to avoid registration?

Has anyone had to deal with researchers claiming that 802.11 RF causes interference with their laboratory experiments and apparatus? We're getting rumblings out of our Physics department - they are trying to prevent APs from getting installed in their area because of what they say are highly sensitive devices that will be adversely affected.
My personal opinion is....well, I'll withhold that for now. Anyone gone through this? Thanks in advance!

We had some voice degradation problems with Vocera in a clinical setting where there was a breakroom with an old microwave right next to areas where Vocera was used heavily. We duplicated the problem by turning the microwave on. I suggested maybe buying a new microwave that would hopefully not be so leaky. They bought a new microwave, but it was just as bad as the first. I remember years ago I had a microwave at home that didn't seem to interfere at all when I did spectrum analysis - I just don't remember what brand or model it was. Anyway, I've been asked to see if I can find any microwave ovens that are more Wi-Fi friendly. Besides going to appliance stores and asking to do spectrum analysis I am not sure how I could find these. Has anyone else researched this or found any brand or model that seems to contain the radiation better than another? If so, let me know. Thanks, Curtis ********** Participation and subscription...

Hello to the group,
I know that this has been discussed before, but I’m coming back around to it. I’m intrigued by 7signal.com and see attractive aspects to their approach, but find myself struggling with:
- Pricing- Seems incredibly expensive
- What’s really being delivered- we are a CleanAir environment, so much of 7Signal would be duplicitous in function, and so far I can’t tell all what one is delivering that the other leaves out
- What 7Signal expects you to do to optimize- there are locations where APs cannot be moved, there are groups of clients that you are likely not going to easily pin down for driver updates, etc, and only so many system settings you can tweak without creating other issues
- Deployment model- given that Eyes themselves need to be cabled, it’s not exactly easy...

Aruba’s AirGroup is not vaporware, but is currently only available as a special technology release. The feature is scheduled to be released in a GA release later this year.
Aruba forked their code so they could develop this feature without impacting their main GA releases. They then merge the tested changes back into the GA release. Aruba followed a similar process when they developed their current Remote AP technology.

Has anyone tried to use a powerline ethernet product as a backhaul to an outdoor wireless access point? The thought crossed my mind today that that might be a possibility. The remote AP can be powered by a light pole and electrical service to that light comes from a breaker inside one of our buildings. If the uplink came from the same place the power does, that would make the installation a lot simpler I think. Now that I've had the idea, I wonder...is this a good idea or a bad idea?

We implemented one of these VEOS units in a classroom last fall. It's pretty neat, but I found the emphasis on wireless to be misleading. The unit itself does not have wireless; it connects to your network via wired ethernet. I think the point is that wireless laptops can visit the VEOS unit via http and download the client, and then a student or guest can then share their screen over the projector. As long as wireless clients can get to the IP address given to the VEOS, then there is no configuration on the network. I hope that this helps.
Thanks,

We have an open case with Aruba on a power issue with the 5Ghz PA when the AP is in Hybrid mode for Spectrum Monitoring. This causes (iin our case) the POE switch to reset the port as it sees the AP asking for more current than negotiated. This action resets the AP and all clients are lost which interpreted to our Helpdesk as intermittent connectivity. Since disabling the Spectrum Monitoring, we have not experienced any further disruptions. We have several controllers running 6.1.3.7 and several running on 6.2.1.0.
Another problem has surfaced for us recently with MAC OSx, in that 10.8.3/.4 may have keychain issues once more with 802.1x authentication. Has anyone else run into this. Of all the complaints, the version has always been 10.8.3 or higher ( it may have been prevelent on earlier versions as well). Testing has shown that removing the entry in the Keychain resolves the problem for short time, but that is only...

We are currently installing some Aruba APs on our campus which has been fully covered by a Cisco wireless network. Both systems are controller based installations, Cisco 5508 Aruba 7210, and both authenticate users against our Cisco ACS server. Both wireless systems are broadcasting the same SSSIDs to provide a common experience for the users. We have run into a situation where all devices connect to both networks without user intervention, except for Apple devices, which request the users accept the certificate from our ACS server. We have run tests using the same device and user ID on both network, but each time the apple device connects to the Aruba network the user is prompted to accept the certificate. We are trying to install the second system without having the users notice any changes. Has anyone had a similar experience they are willing to share.

We are considering a forklift replacement of our Meru wireless infrastructure since a significant portion of it is approaching end-of-support life (all the controllers and over 2/3s of the APs) and we’ve had our share of problems with Meru. I was wondering if any of you who have recently re-bid your wireless have a set of requirements or an RFP you would be willing to share – either publicly to the list or privately to me directly – so I’m not starting from scratch.
FWIW, we currently have six MC3000 controllers and 424 APs providing ubiquitous indoor coverage (admittedly with some weak spots). Bradford Network Sentry provides the NAC (wired and wireless). I do not intend to have a full site survey done as part of the bid, but will increase density in some known problem locations. I also lean toward continuing with the controller-based/thin-AP...

campus network, etc. We are looking at some form of Identity Service to push users into particular vlans, and that isn't working that great at this time. So what are you doing or going to be doing to resolve this type of issue.

We have a request to support Airplay/Apple TV's on our enterprise network so that instructors can mirror presentations from their iPad's to classroom and meeting room projectors. For performance reasons, we suppress multicast on our wireless networks and to conserve IP address space we dynamically assign users to wireless subnets so that two devices in a room may be on different IP subnets. So for right now it's not possible on our network. Of course the next question we get asked is if instructors can bring in their own "temporary" access points to do this.

Hi. Are you using RRM to manage the radios? If so what is the reported power output RRM is setting? If you manually set power to max do you get a performance increase? We have both 3602i and 3602e series with dipoles you mention with no issues. We are running 7.2 code currently but plan to goto 7.5 later this summer.

All,
All,
It seems an alarmingly high number of wireless devices have returned to our campus this week. After at least of year of steadily increasing numbers, we are now seeing a roughly 40% increase since last December. At first I didn't believe what I was seeing and opened a case with the vendor to confirm reporting was accurate. Tied into this, we upgraded by a major version earlier this month and I thought this could be related. Apparently not the case, everything we've looked at tells us that the numbers are accurate. I'm still looking a stats, but haven't been able to come up with anything yet.
Is anyone else seeing this magnitude of increase in devices over winter break ?

I was wondering what other schools have for a ratio of students to
AP's in the residence halls, either definitely or approximately?
If you have such a number, how do you count dual-band AP's? They're
doing more than a 2.4GHz AP, but not quite as much as two AP's.
Then one last related question... Would anyone know their relative mix
of 2.4GHz vs. 5GHz connections in residence halls?
Thanks.

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.

Today it is AppleTV, tomorrow it will be a different device/use/software. The underlying issue, as others have noted, is the Bonjour resource discovery mechanism, what Apple likely needs is a directory service. Once that is solved, the problem will then shift
to authentication/authorization/accounting and scalability. I'd suggest:

As I've said recently, I really wish that there was a standard that all APs would use and all controllers would use so that they could all talk together. I know this is probably unlikely to happen, but we have interoperable wired networks and I just wish the same for the wireless side. Maybe a universal controller is more realistic, something that understands how to talk to all types of APs.

I'm no longer directly involved in the WiFi here, but I was helping
someone with a Microsoft Surface (Intel version) that is perfectly
up-to-date. My Mac Air WiFi worked perfectly with our Aruba AP throughout
the exercise. His would connect, get DHCP, get a lease renewal in five min
(ten min lease) and a few minutes later Windows would tell him he had
"limited" Internet, but in fact he could only ping his own IP and not the
router (that's pretty limited!). The WiFi bars icon never wavered. I'm
suspecting a failure to renegotiate keys.
Anyone else seeing Surface WiFi issues?

So we're looking at an eduroam deployment here, and one question that has come up is one of credentials. Here at NU, we have 2 identifiers - the NetID and the alias. All of the directories and the like are keyed off of the NetID, which does not have to be the same as the alias. Top-level email addresses take the form @northwestern.edu.
Under a basic default eduroam deployment, a user would use @northwestern.edu as his/her username to authenticate to the wireless network. This is not 100% ideal from an end user point of view, though, since that could potentially lead to some confusion since at least here, netid rarely is the same as alias. Obviously, at some schools, netid = alias, so this is a moot point, but have other schools encountered support/documentation issues because of this?
As an alternative, has anyone looking into using a subdomain for the realm? i.e., @eduroam.northwestern.edu?

I'm curious if any Cisco users out there are experiencing or have
experienced what we're seeing on our campus. This past summer we
installed 3502i's in all of our residence halls - approximately 500
total. Ever since the students have moved in, we will get messages from
WCS stating that "AP XYZ" is down and disassociated from the
controller. When I check out the AP, the uptime is fine, but the
"CAPWAP join time" is for like 30 seconds, or however long it took me to
check.
We've tracked this and it is totally random as to what AP will drop,
which makes troubleshooting this very tough. The log on the AP isn't
helpful. I'm working with TAC who suggests that keepalives are getting
missed. I'm not sure why that would be the case since we have another
500 or so APs on the admin side that very rarely drop. Adding to that,
when the students left for break, the AP drops stopped. They came back,
and sure enough, the drops start up again.
I will say that the AP always...

Greetings all!
The recent thread on residence hall AP placement, coupled with our own performance issues that we are getting reports on from the residence halls, has prompted me to throw together another survey so that we can present some data to our Student Affairs department as to what other schools are doing in this space.
Our own issues that we are seeing are the familiar ones of co-channel interference due to APs in hallways, rogue APs, higher/lower signal attenuation leading to bad coverage/performance, and an overall higher level of client device density.
is the URL for the survey. We will be collecting results through Friday, February 22.
Thanks in advance for any feedback that you can provide! Please note that I am not a professional survey writer, so any structural deficiencies in the survey and/or the questions are completely my fault. :)

Management wants an SSID for guests which does not require a password. My corporate reaction is “that is crazy”. My secondary/new to academia reaction is “why not”.
If the guests network is completely separated from the internal network, severely limited in bandwidth, web filtered, protocol/applications blocked etc. Who cares? The only potential issue I could see is web filtering can’t stop everything.
Then there is the whole question of how to handle “personal devices” for staff and students. Any thought on that would be appreciated as well. Thinking of hidden SSID (simply to make it...
