After making the above configuration changes, run this command:
sudo ifdown wlan0 && sudo ifup wlan0
Then check your IP configuration:
ifconfig
If you have trouble connecting, try to connect manually by running these two commands:
sudo wpa_supplicant -B -iwlan0 -c/etc/wpa_supplicant/wpa_supplicant.conf -Dwext
sudo dhclient -v wlan0
Some other useful commands:
# you can run this command to view a list of wireless networks in range
sudo iwlist wlan0 scan
#run this command to view the connection status of the wireless network
