We also see lots of problems with Macs being unable to obtain DHCP addresses properly eventually ending up with a self-assigned IP address.
Attempts to engage Apple have not been helpful. -Neil -- Neil Johnson Network Engineer Information Technology Services The University of Iowa Work: 319 384-0938 Mobile: 319 540-2081 Fax: 319 355-2618 E-mail: neil-john...@uiowa.edu > -----Original Message----- > From: The EDUCAUSE Wireless Issues Constituent Group Listserv > [mailto:wireless-...@listserv.educause.edu] On Behalf Of Chris Brezil > Sent: Thursday, October 07, 2010 8:28 AM > To: WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU > Subject: [WIRELESS-LAN] Apple and wireless connectivity issues? > > Over the summer we upgraded our wireless infrastructure from all > autonomous Cisco access points to a managed Aruba wireless environment. > Since the start of the semester we have had issues come up that we have > been addressing, but we are now encountering something that we never > faced before - it seems more and more that the majority of new issues > we are dealing come from Apple laptops and mobile devices.
