FAQ

Find accesspoints

Find device first

iwconfig

Find them:

iwlist wlan0 scanning

This shows a list of accesspoints with their ESSID

"interface doesn't support scanning" sometimes means you're supposed to 'ifconfig wlan0 up' first :)

This works depending on modes set. On my orinoco gold: -ad-hoc: finds itself -managed: nothing found -monitor: "doesn't support scanning" -master: SET failed on device eth1

Connect to accesspoint, assuming no encryption or WEP

iwconfig wlan0 key s3cr3tkey

or

iwconfig wlan0 key off

iwconfig wlan0 essid SomeEssid

If connected:

dhcpcd wlan0
