Reducing unnecessary interference...

[Jeff Kell]

This is our first real "production" year on having wireless coverage in
our residence halls.  We had VERY limited availability before, typically
some commons areas, but we finally obtained funding to go all-out.

There have been some early complaints of weak spots or coverage holes. 
In  investigating these, we are discovering a number of user devices are
generating interference, particularly on 2.4G...  wireless routers
(which we don't support and do quarantine), but even more wireless
printers pushing out their ad-hoc "configuration" default SSIDs.

Has anyone done a laundry list of "how-to" guides to disable wireless on
any of these devices?  There are too many of them out there for us to
try to address individually, but hopefully an email word-of-warning and
explanation, along with a link to how to resolve the issue would be
sufficient for most.  But we're not sure where to start :)

agreed- this is one facet of Cisco's framework that impresses.

It will happily run that number of devices and clients day in and day out. The 
10-core CPU never breaks a sweat.

Hi all,
Rarely can one take the published capacity numbers of devices at face 
value.   The Cisco 5500 series wireless controller is rated to handle 'up to' 
500 APs and 7000 concurrent clients.  Has anyone pushed this device to 
capacity?  If not, what limits have you decided on?

..thanks in advance..Jamie
