sudo iwconfig wlan0 essid Karam
sudo iwconfig wlan0 mode managed
sudo iwconfig wlan0 channel 11
sudo iwconfig wlan0 key s:alikaram
sudo ifup wlan0 # This one gave me an error "ignoring unknown device wlan0=wlan0" so I used --force
sudo dhclient wlan0

No good, so I tried this

sudo ifconfig wlan0 10.10.10.3 netmask 255.255.255.0
sudo ifup wlan0

No good, so I tried adding auto wlan0 and iface wlan0 inet dhcp

Still no good
