Wireless NetworkingΒΆ

If you have your Ethernet cable plugged in, you should automatically get a DHCP address on eth0. Alternatively, you can bring up the wireless interface with a DHCP address using Network Manager by running the text user interface from the command line:

purism@pureos:~$ nmtui
  1. Select “Edit a Connection”. Hit enter.
  2. Arrow over to “Add”. Hit enter.
  3. Arrow down to “Wi-Fi”. Hit enter.
  4. Wifi settings:
    • Change the name if you’d like
    • Arrow down to SSID and enter your wifi network name.
    • Change the “Security” from “<none>” to the correct wifi security type (“WPA & WPA2 Personal” is most common) and enter your wifi network password on the field below.
    • Arrow down to “OK” and hit enter.
  5. Now you are on the screen with the list of your network connections where you should now see your wifi connection listed. Arrow to “Back” and hit enter.
  6. Arrow down to “Activate a Connection”. Hit enter.
  7. Select your wifi connection and then arrow over to “Activate” and hit enter. You should see a pop-up that says “Connecting” and when that pop-up goes away, your connection should be active. Arrow down to “Back” and hit enter.
  8. Arrow down to “Quit” and hit enter.
  9. Now, back at the command prompt, running ip addr should show that your wlan0 interface has a DHCP address and your packets should be able to reach the outside world.
