I've deployed 20 of the Cisco 3500i access points so far for testing and my
early experience was mixed with them, but it's starting to look up.
The first issue is that you have to run version 7 code, since I'm running WiSMs

I would recommend waiting for the 7.x MR1 code. We currently have 7 WiSMs and
use webauth with an external webserver and encountered massive problems with
the 7.0.98.0. When there were a lot of webauth logins on a WiSM it would
become unresponsive over its management interface and thus would
After talking to my SE and one of the Engineers in the Wireless BU they have
confirmed that 7.0.116.0 is indeed MR1, and they are calling 7.0.98.218 MR

Currently we're addressing this issue by installing the 3500 series Cisco Clean
Air Access Points in all of our dorms and increasing the number of APs in the
dorms while we do it. These access points do interference detection and will
map it in Cisco WCS. I have a feeling it's probably going
I've found 7.0.116.0 to be very stable, I've been happily running it since late
April on 7 WiSMs and 1 4400 series with no issues, and since late May on two
WiSM 2s. It also incorporates some new features not found in 7.0.98.218. As
for APs we've got a mix of 1131AG, 1142N, and 3502i for

We purchased a few older apartment buildings which we converted to dorms and
are doing wireless only in them. For the wireless we’re using Cisco 1142i and
put one per apartment (some apartments are 2 beds, some are 4).
As mentioned you definitely want to do PoE on the switches to provide
Same here, I've had to expand subnets for 15 buildings since the semester
started (we give each building a subnet), and looking at the logs I've got
another 5 or so that will need it in the near future. More buildings that used
to be good on a /24 are requiring a /23, and buildings that had

We hit the same issue here, we have 7 WiSM 1s and 3 WiSM 2s. I had just
finally gotten away from a mixed code environment this past summer after
putting the last 1010s out to pasture and now there's this.
On our end we're working to fund replacing the WiSM 1s with WiSM 2s this
summer, fingers

The only caveat I ran into when first installing them last summer was the
requirement for 12.2.33-SXJ on the chassis, but the need for an upgraded IOS
image on the switch is understandable as it was a new module at the time.
Since then I've been running three of them across two chassis with my

then L3 web authentication will fail to work (both internal and external). The
workaround is to delete the 60th and any further interfaces
Do you have 60+ interfaces defined by any chance? If so you're hitting bug

Yeah, my guess would be they're probably baking a version of avahai into the
controller code similar to what Aerohive is doing.

I asked many of the same questions as Anders without a reply so I'm also
wondering if they just weren't prepared/hadn't thought of the problems
associated with having the devices on wired, if having vlans across a L3
boundary will require a controller there to terminate them, and if/how roaming

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

I got a Fluke AirCheck this summer and have found its locate feature to work

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.

I didn't see it happen on any of my 3600s, but under 7.2.110.0 I was seeing
intermittent crashes on my 3500s (using WiSM2s). TAC suggested I try upgrading
to 7.3.101.0 which I did Sunday, also they provided a debug image to load on my
3500s so that if it happens again they can grab more
Mike,
With the WiSM2 on 7.2 you can use RF Profiles to manage your thresholds.
The option is under Wireless-RF Profiles and then you can assign it to APs
under the AP Groups (WLANs-Advanced-AP Groups). This way you can tweak the
settings at whatever scale you want.

On pre-7.4 code as long as you're on the same layer 2 vlan as the AppleTV and
have multicast enabled you'll still see the advertisements and be able to use
it, it's just when you try to cross L3 boundaries or disable multicast that
you'll need 7.4 or greater.

The whole idea behind Wi-Fi Direct is to be able to stay connected to a
wi-fi network while making an ad-hoc connection at the same time to a
device. So this will not be an issue. Battery life on the other hand...

I second Julian's opinion about speed on older devices as I too got stuck with
a terribly slow iPhone 3G after the iOS 4 upgrade. I did, however, take the
