I have just upgraded a client with a WLC (2504) and 3 LAPs (1141Ns) with tighter security (RADIUS and WPA2). My client has a /23 internal network; for this scenario, let's say, 192.168.30.0 and 192.168.31.0. Their old wireless was via three 520Gs all with 31.x IPs. DHCP is on the 31.x subnet and everything on the 30.x subnet is hardcoded. The default gateway has a 30.x IP. All works well; however, under the the WLC (which currently has a 30.x IP) and LAPs (which I have tested with IPs from both networks), we cannot wirelessly print to printers (which have 30.x IP numbers). We can print fine via the 520Gs.
Does the WLC need to be on the 31.x network? And if so, why?
As long as you have routing between the 192.168.20.x and the 192.168.31.x, you should be able to print. Can you ping the printer from the wlc or can you ping a client from one subnet to the other subnet?
I have a workaround and a clue to the problem. If I install the printer using "HP Socket" (IP), I can print. If I use the Xerox's packaged driver/installer (pkg file), I cannot print. I will be contacting Xerox.

This is the start of a display filter cross reference between Wireshark and OmniPeek.
The 1st installment is a table of advanced filters. More filters will be added as time allows.

I have created a Powershell script to automatically add a Wireless Guest User on Cisco WLCs. (tested on 2500 Series)
The script should be completely self explanatory.
