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.

Even with a portal, don't devices still get a DHCP lease?  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.

Matthew,

That may be the issue. Our Guest SSID has a portal, but for a while we ran an 
open SSID with no portal.
With no portal, we quickly found DHCP scopes filling up due to mobile devices 
constantly associating, checking for Internet access as they roamed around 
campus.

I’ve seen my test laptop (Latitude D630 + Intel 7260-AC) with Windows 10 Tech 
Preview on it do this. I think the enabled-by-default Wi-Fi Sense feature that 
seeks out open Wi-Fi is the culprit, at least for me.

I really have to question the logic of having a computer auto-connect to any 
unsecured network that it comes across…. After connecting to our .1X network, 
it usually stays there, but at first boot if the EAP auth takes more than a few 
seconds it gives up and goes for the guest network even though I’ve deleted the 
profile for said guest network.

I’m having similar problem on a Win7 SP1 laptop.  When I enable my wireless 
adapter it connects to our guest network instead of our 802.1X network.  The 
order of the profiles in the network list doesn’t matter, and even deleting the 
guest network profile doesn’t help.  Once I manually choose the 1x network it 
doesn’t generally “jump” to guest, but I recall that happening at least once.  
My theory was that my connection dropped, giving my machine a chance to 
exercise its newly-found preference for the guest network over all others.  I 
don’t have this problem on any other devices, and I haven’t heard any reports 
from anybody else yet, so I assumed my laptop was the problem.  That said, the 
laptop was problem-free for years.  If the problem coincided with an AOS 
upgrade, I failed to make the connection.

When I thought this was just a problem with my laptop I opted to work around 
it, but maybe it deserves some attention.  Windows devices make up a modest 
percentage of our wireless clients, so others could be having the same 
experience and word just hasn’t reached me yet.  I’ll get a packet capture next 
time I put this device on the Wi-Fi.  If I turn up anything suspicious I’ll 
post to the group.

I have not seen this here at Liberty University with our Aruba 6.3.1.16 
network. We will be moving to 6.4 soon.

In fact, I use a Surface Pro 3 as my daily computer.

  Anybody else seen this?  I’ve seen devices reconnect to the sane SSID as a

  Is this a Windpws 8.1 (mis)feature?  An Aruba bug?  A quirk of the wireless

RE: SSID jumping with Win 8.1 (Surface Pro 3) on Aruba

2015-07-21 Thread Jason Cook 
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.
