I did some research and found that you first need to use the command
sudo iwlist [interface] scan
to be able to find available wireless networks within your area.
Then you use a series of iwconfig
commands to configure your wireless interface to point to one of the wireless networks found by the iwlist [interface] scan
Then you finally issue the command
sudo dhclient [interface]
to get an IP Address from the selected wireless network.
My question now is what essential iwconfig
commands are needed to configure my wireless interface to connect to the open/unprotected wireless network or hotspot.
