I have two Location with IAP-135 and IAP-134 mixed. One location on has 3 IAPs and the other has 8 IAPs. They both have two different DHCP servers The one with 8 uses a IP helper on the router for an off site dhcp server and the one with 3 has a local one. They have one SSID that uses 802.1x and one SSID with WPA2-PSK. The problem I am having is that some client, maybe 2 or 3 at a time, will authenticate but wont pull an IP address. It is different devices each time but does seem to be Apple device more than others, and it will happen on both SSIDs. Most of the time after a couple of hours they will get an ip. I can see in ClearPass that the clients do pass authetication. Has anyone else seen anything like this?
