Re: [WIRELESS-LAN] iPhone - Incorrect Wi-Fi Password Error
By any chance, are you max’ing the pmk-cache on your WLC (“show pmk-cache all”)?

RE: [WIRELESS-LAN] iPhone - Incorrect Wi-Fi Password Error
I had a ticket from an IT staff member reporting the same “wrong password” or “prompted for password.” When I looked at the screen capture he provided it says “Enterprise Wi-Fi Network Do you want to continue joining this network?” Maybe not exactly the same thing but the user says it is prompting for password. The iPhone device appears to be onboarded/configured correctly. The staff member documented the time/location (as good as memory serves) for us. During the reported time we did not see anything in our logs (syslog, radius, Nyansa.) For whatever it’s worth, Prime did not report any rogue APs/SSID in this area for the timeframe in question. I am definitely curious but have not had time to do much investigation. And again, this is user reported so maybe not 100% accurate information. Since this is an IT staff person, I will ask the user to run the “Net Analyzer” tool and tell me the Wi-Fi BSSID after clicking the Okay. Unless someone knows of an IOS built in tool to tell you the associated BSSID? I tried the Airport utility but it does not show anything for me using Cisco LWAPP and no multicast. (typically use the Wi-Fi scanner part but that does not tell if the device is associated, just signal level) *Mike Atkins * Network Engineer Office of Information Technology University of Notre Dame *From:* The EDUCAUSE Wireless Issues Constituent Group Listserv [mailto: WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU] *On Behalf Of *Watters, John *Sent:* Monday, January 29, 2018 5:03 PM *To:* WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU *Subject:* Re: [WIRELESS-LAN] iPhone - Incorrect Wi-Fi Password Error If you do message logging from the controller, you might have luck finding entries on your log server by searching for the MAC address and/or the user name.
