Connected to a
wireless network
via
wpa_gui
If you need to connect to a different network in the future, simply start the process again
from the beginning. Connecting to a new network won’t cause
wpa_gui
to forget the old
network; both will appear in the drop-down list, and you can connect to any network in
range simply by choosing it from the list, once configured.
You can also use
wpa_gui
to disconnect from a wireless network without having to remove
the wireless dongle physically. Simply click the Disconnect button at the bottom of the main
window and after a few seconds your Pi should be removed from the network. To reconnect,
click the Connect button.
Connecting to a Wireless Network via the Terminal
If you are running your Pi without a graphical user interface, you can also connect to wireless
networks at the terminal or console. First, check that the USB wireless adapter is working as
it should by using the
iwlist
command to scan for nearby wireless access points. This list
will probably be larger than a single screen, so pipe the command’s output through
less
to
pause after each screenful, like this:
sudo iwlist scan | less
