RE: SSID jumping with Win 8.1 (Surface Pro 3) on Aruba
Apparently once a device sees there is no direct Internet access it stops trying, at least for a period of time. We found the portal made a huge impact on our DHCP usage.

We had to deal with this by making our subnet and DHCP scope large enough for any potential mobile devices automatically associating, even if they didn't have credentials for the portal. ** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/groups/. ** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/groups/.

RE: SSID jumping with Win 8.1 (Surface Pro 3) on Aruba
We haven't seen that with Windows but we have seen the same with OSX 10.10 hosts. Not during auth but at some point while the users are working. Our suspicion is that the OSX host is failing re-auth or for whatever reason is being disconnected from it's preferred network then join's the best next on list... However the client chooses. In this case potentially with no known networks available it's picking the best open network as it's probably instructed to do. We haven't gone in-depth with it yet, seemingly small impact and many things to do. Likely we'll be logging a case with Apple in the next month. -- Jason Cook The University of Adelaide, AUSTRALIA 5005 Ph: +61 8 8313 4800 From: The EDUCAUSE Wireless Issues Constituent Group Listserv [mailto:WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU] On Behalf Of David Gillett Sent: Wednesday, 22 July 2015 6:07 AM To: WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU Subject: [WIRELESS-LAN] SSID jumping with Win 8.1 (Surface Pro 3) on Aruba Anybody else seen this?
