Devices blocked from accessing internet through Cisco Wirelss APs

I just took over the IT Department here and things were quite the mess I'm still sorting it out.

Background: Several users were apparently taking up bandwidth on certain devices by streaming movies etc..  Previous Network Admin went in and blocked those devices from accessing the internet.  These devices are not blocked on the firewall.  Somehow what was done was done through the AP's.  These APs each have internal ip addresses I am unable to telnet or ssh into any of them.  I doubt that the previous network admin consoled into an AP to block these devices its specifically an Iphone and an IPad.  The Network Admin is no longer with the company nor is the person who previously used the device yet they are still blocked.

Current : I have already checked the firewall and there is no rule denying internet access to these devices which in my mind tells me it must be configured somewhere in the AP's.

Do you have a Cisco Wireless LAN Controller (WLC)?  It sounds like your APs are running lightweight code so It would have most likely been done at the WLC.

There is no documentation to support that we are using a WLC so the hunt begins!  They did not know that our AP's could transmit two SSID's so we literally have to separate AP's side by side in several locations one for our guestnet and one for our corpnet.  So that means two WLC?

No you can run multiple APs on one WLC and you can run multiple SSIDs on one WLC.

If you connect a console cable to one of the APs, what prompt do you get?

What part-code is on your APs (label on the underside starting AIR-)?

So my predecessor consoled into every AP and blocked specific devices by mac on each AP.  I had to go into each one individually and unblock.  Problem resolved.  Thank you for your help.
