I do not know about that log, but here are things we have found. 1) Disable IPv6 (as mentioned)
2) Remove Wi-Fi network and then re-add (use the + and - buttons under the list in System Preferences/Network) If after doing those two you are still having problems we have had to take the nuclear approach. This is less if simply not getting an IP, but more of not connecting automatically and disconnecting. 3) Remove underlying plist config files (also remove Keychain entries). We have had this more than I would like. I removes all their saved wireless networks, but improves stability. The file for newer versions of OS X is at /Library/Preferences/SystemConfiguration/com.apple.airport.preferences.plist ------------------------ Walter Reynolds Principal Systems Security Development Engineer Information and Technology Services University of Michigan (734) 615-9438 On Mon, Jan 27, 2014 at 1:40 PM, Lee H Badman <lhbad...@syr.edu> wrote: > Try disable IPv6 on Mac. > > Lee Badman > Network Architect/Wireless TME > ITS, Syracuse University > 315.443.3003 > > > -----Original Message----- > *From:* John York [yo...@brcc.edu] > *Received:* Monday, 27 Jan 2014, 13:17 > *To:* WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU [ > WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU] > *Subject:* [WIRELESS-LAN] Mac problems > > Hi folks > > > > I have a WLC5508, currently on 7.4.110.0, and am having a problem with a > Mac laptop that appears to connect but does not get an IP.
