## Basic Linux WiFi/WPA2 configuration These are helpful if you don't have network-manager or whatever installed, eg if you are on a headless computer with no wired ethernet. Basics with `iw` and `ip`. These tools can't do WPA2 on their own: iw dev ip link set wlp3s0 up iw wlp3s0 link iw wlp3s0 scan iw wlp3s0 scan | grep WSSID Do WPA2 setup and DHCP: wpa_passphrase W.A.S.T.E. > /etc/wpa_supplicant/wpa_supplicant-bootsrap.conf # enter password wpa_supplicant -D wext -i wlp3s0 -c /etc/wpa_supplicant/wpa_supplicant-bootsrap.conf # leave running in a terminal dhclient wlp3s0
