Strange WiFi behavior on Cisco Enterprise APs

Hi,

I'm seeing behavior on my 4th Generation X1 Carbon Thinkpad using the Intel iwm NIC that is odd.  Basically on simple networks, everything is AOK.  An example of this might be a router at home, or a coffee shop.  However, with Cisco enterprise endpoints where there are many per floor of a multi-story office building, the driver seems to go wacky and try to roam to other endpoints.  I end up pretty quickly in a situation where I have connectivity to the network but I have no ability to surf out of my laptop.  The network-manager icon in my Gnome 3 toolbar turns to a question mark.  We are running 802.11x with PEAP and MSCHAPv2 and no certificates (auth is by userid and password).

I'm latest & greatest as of a few minutes ago (I'm pretty obsessive about staying up to date - keeps me out of trouble).

Any suggestions of troubleshooting that I could try?

Thanks!

Try downgrading wpa_supplicant and check if it works again. See: https://bugs.archlinux.org/task/54233

Seems to be stable with the downgrade.  I stuck wpa_supplicant in my /etc/pacman.conf to not be upgraded.  Does anyone know if anyone is looking into the problem?

Thanks for the pointer BTW!

Re: Strange WiFi behavior on Cisco Enterprise APs

And I spoke too soon.  Not one minute after I posted this it did its trick again. I really think it's just too aggressive about switching APs and gets itself mixed up.  Any way to reduce the aggressiveness of it?
