How can I stop getting disconnected from my enterprise WPA2 wifi network every ~ minutes?

When I'm connected to my school's wifi network, which is an enterprise WPA2 network, using PEAP authentication and MSCHAPv2, I get disconnected every 30 minutes to an hour. It won't reconnect, and the only way I can get it to reconnect to the network is to flip my hardware wifi kill switch (on my laptop, which is an MSI x350

Here's what I assume is the relevant output of lspci:
03:00.0 Network controller: Intel Corporation WiFi Link 5100

And here's (probably too much, but I don't know what's relevant) stuff from my system log:

I'm using Kubuntu 11.10 with the KDE4.8 backports. But I've been having this problem with this machine since I bought it and was using Ubuntu (unity) 11.04. The problem persists no matter whether I use the gnome network manager or KDE's.

Edit: I'm now using GNOME again, but having the same problems.

It seems Network-Manager is too aggressive with changing access points and thus causing random dis/re-connections. Try with wicd

sudo apt-get install wicd

apt-get remove network-manager

Edit or create /etc/wicd/encryption/templates/peap-mschapv2 as follows:

name=PEAP with MSCHAPv2

author=Cereal

version = 1

require username *Username password *Password

-----

ctrl_interface=/var/run/wpa_supplicant

network={

        ssid="$_ESSID"

        scan_ssid=$_SCAN

        key_mgmt=WPA-EAP

        eap=PEAP

        phase2="auth=MSCHAPV2"

        identity="$_USERNAME"

        password="$_PASSWORD"

}

Now you need to enable this template for wicd (after which you need to close and re-open wicd or reboot):

echo "peap-mschapv2" >> /etc/wicd/encryption/templates/active
