Just recently I am having issues with my WLC 2106 WiFi network and iPhones. For the past week, the iPhones have been locking up the network much like as it was described with the ARP issues with the exception that what I have been reading, this issue did not effect the 2100 series.
I've done searches but have not found anything applicable to what is happening now.
apart from someone having iphones and 2106, not sure if people can help you without more information. can you tell us which version of software you have ? Can you collect a "debug client " showing the issue ?
Maybe it's linked with the iphone going to sleep mode ?
It's running on v. 22.214.171.124. Right now I'm controlling who is accessing the wifi via MAC filter to prevent anyone with an iphone to log on but that just doesn't cut it since there's a lot of visitors coming in to use the wifi.
I won't be able to go in and do more testing for a week or two to get that debug log.
But this seems to be a common issue with at least the 2106s. As soon as anyone logs in with an iphone, the controller locks up and the only thing to do is reboot. It only fairly recently started happening so maybe it's only with the newer iphones?

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.
