I am in the middle of migrating 3502i's from WISM to 5760 wireless controllers and have come across a troubling problem. I have a few different SSID's advertised and 7925's connect and roam fine. Windows devices connect fine to all SSIDs however apple iDevices and macbooks will connect to all SSIDs but on a few will not surf via dns. If i manually enter a web url via IP they resolve fine.
They get DNS via dhcp and if I do a nslookup from the mac it will resolve dns however it will not surf the web.
I can't figure out why apple devices don't work on these SSID's but android and windows devices do. To make it even more troubling I took an old ipad on ios 5.1 and it worked.
Just to update this thread. After opening a TAC case and doing some packet sniffing and troubleshooting we have narrowed the problem down to the 2.4ghz band. If I enable all radios on the problem SSID's apple devices will associate via 5ghz and work fine.
TAC has not gotten back to me with any further info yet.

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.

The script should be completely self explanatory.
