Hi Tom.
The issue we've had is not one of density but one of coverage; in some site
surveys we'e conducted recently in our residential spaces, we are finding that
one AP might cover only a small amount of students, say, 6-12 reliably.
The challenges have been that our residential halls are
campus) and return the appropriate Tunnel Group ID for AAA override.
If there is no attribute in LDAP, we place them on the guest VLAN by default,
however, the guest VLAN and student VLANs are identical in terms of access
control.

Hi,
We're looking into this, too.
What's the best way to obtain data as to which clients are only 802.11b-capable
on a Cisco environment? I do see a few connections at 802.11b data rates but
we'd ideally like to know how many legacy devices out there that we have.
Cheers,

Hi,
We experienced this with devices updated to iOS 6.1 - and observed on the iPad
3rd gen, iPhone 4, 4S and 5.
The symptom was that the phone would not automatically reconnect however would
manually connect when the network is selected.
The resolution was to reset network settings on the
the issue.
The workaround on the device configuration with this RF profile present is to
set the Realtek NIC to do 802.11b only. For some reason, this works!
Has anybody else run into this issue?
Cheers,

Cisco advised we were hitting bug CSCtx03556 which I believe is still present
in 7.3.101.0.
We are now running a version of code that resolves the issue and we haven't

Hi,
We're running an engineering variant of 7.2.113.0 to resolve some issues we
were having with AP stability.
We're looking into 7.5 for 802.11ac support. Is anyone running 7.5 out there
or should we wait?

Unfortunately we haven't spent enough time with a client device that's been
broken long enough to investigate further.
We've seen this on 1131, 3500 and 3600 series APs.
We're on a 7.2 engineering release but are planning for 7.5.
