We have had lots of problems with firefox and our aruba in general when used with the captive portal. You didn't mention if this is 802.1x or CP or WPA but safari and firefox seem to have problems with our CP on aruba over wireless only.
From: The EDUCAUSE Wireless Issues Constituent Group Listserv [mailto:WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU] On Behalf Of Hanset, Philippe C Sent: Wednesday, June 01, 2011 3:38 PM To: WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU Subject: [WIRELESS-LAN] Strange behavior: iMacs 2011 All, (I checked the Archives and couldn't find anything on this) One of our desktop support guy is losing his mind on a problem with three iMacs that have a very erratic behavior on wireless only. -Those iMacs were purchased during the last month. -They can join Wireless -They can get a DHCP lease -Ping, traceroute, etc.. works -Web (Safari or Firefox) doesn't work at all (either by name or by IP address) This is on an Aruba infrastructure (AP-125 with M3 controllers). There is a discussion about this problem at: https://discussions.apple.com/message/15166297#15166297 Anyone else facing this problem? Any resolution (we have contacted Apple... but that might take a while)?
