wpa_supplicant cannot connect after disconnect
 

No matter if the wireless encryption is simple WEP or WPA2 with PEAP, if my wpa_supplicant disconnects with message "network is down", fails to associate again. Authentication keeps timing out until I reboot. This happens both with my Neo Freerunner phone and laptop. Killing wpa_sup with ^C doesn't help either. How do we make wpa_supplicant reconnect? Here's my conf and command line.

network={
ssid="tue-wpa2"
key_mgmt=WPA-EAP
eap=PEAP
identity="some_identity"
password="some_password"
}

wpa_supplicant -ieth0 -c /etc/wpa_supplicant/wpa_supplicant.conf

I am not a networking expert (or even a talented amateur in that regard), but restarting the network is usually straightforward. Open a terminal window, log in as root, and enter the following command:

service network restart

If everything is working OK but the system just lost connectivity, this should get things going again.
