Hi Jeff, Thanks for the suggestions.
We are running a single controller, so inter-controller roaming isn’t an issue. On both 802.11a/n/ac & 802.11b/g/n the lowest data rate supported is 12 Mbps, and we have that set to mandatory. So I think we are also good there. Thanks Sean From: The EDUCAUSE Wireless Issues Constituent Group Listserv [mailto:WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU] On Behalf Of Jeffrey D.

If so, I’d look to make sure inter-controller roaming and mobility groups are operating correctly. Have you removed the lower data rates from your AP’s so that clients don’t stick as long to distant APs?

I like your other thought about the AP power and cell size in relation to the clients output power. This never crossed my mind at the time, but I will certainly be looking more into this.

We use Radiator RADIUS for our 802.1x wireless network and were seeing errors in the logs that accompanied the credential pop-up. It appeared as though the RADIUS controllers were receiving a large number of spurious packets mid-EAP transaction from our Cisco WISM2s. That seemed like a bug, but I was able to work around the issue by ignoring the offending packets and never re-visited it. Not sure if you are able to debug that deeply with ISE to see if that could be an issue. Another thought, are your AP radios set to maximum power? It’s possible that the user is at the edge of a coverage area and their device’s radio simply can’t reach the AP.

We have had a couple of reports of iPhones throwing a “Incorrect Wi-Fi Password” error when the client is trying to join a network while walking around campus. The error resolves itself quite quickly if they hit cancel on the message as the correct credentials are cached on the device. When I check the logs on our ISE server I see that the client never actually made an authentication attempt. So it may have been blacklisted on the WLC, unfortunately I don’t see a way to report on historical exclusion events. No other client devices have been reported as experiencing the same issue, and it doesn’t appear to occur in the same geographic region. So I’m thinking this is a client side problem.
