RE: [WIRELESS-LAN] SSID jumping with Win 8.1 (Surface Pro 3) on Aruba
I typically see that 30-50% of devices which associate and get a DHCP lease from our wireless networks never log onto the portal and actually use the wireless connection... This apparently includes many devices which remain on campus (plugged in to charge?) overnight. (Our guest network does have a portal, it just doesn't do any stringent authentication...)

RE: [WIRELESS-LAN] SSID jumping with Win 8.1 (Surface Pro 3) on Aruba
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.

Re: [WIRELESS-LAN] SSID jumping with Win 8.1 (Surface Pro 3) on Aruba
Not sure if this will help at all. With Cisco the surface will not connect to a secure SSID with PMF dot1x set as optional. We had to disable PMF dot1x and only use dot1x. There are some strange issues with the wireless on the Surface.
