ps show that wpa_supplicant try to connect to william instead of will. That is the cause of your problem.
your interfaces file should be as follow (/etc/network/interfaces):
iface wlan1 inet dhcp
pre-up wpa_supplicant -B -Dwext -iwlan1 -c/etc/wpa_supplicant.conf
post-down killall -q wpa_supplicant
iface eth0 inet dhcp
your /etc/wpa_supplicant.conf (there was 2 mistakes in a previous post, remove proto=WPA and set auth_alg to SHARED)
wep_key0=9E67733554 #Here type your wep key in hex, it s given by your router
The following commands should work as root
Check if wpa_supplicant is still running by typing ps ... as described in a previous post. If it s still running kill it by typing as root "kill -9 777" replace 777 by the pid of your process.
Restart wlan1 by typing as root ifup wlan1
It should go on. if not, restore your interfaces file as it was initialy set.
Normaly on ubuntu configuration is easy through the graphic interface.Remove all your wireless connection and create it again, be ware to type will instead william. Follow any tuto on the web.
