There is a netbook under ubuntu 14 lts , there is a router with wifi and wps , the password is unknown, but the wps-pin and mac-address are known.

How to connect to wifi by pressing the wps button on the router?

free translation of the answer to the question: How to connect to Wi-Fi AP through WPS? taking into account this information (hereinafter it is understood that your wifi interface is called wlan0 ):

  1. create (or edit) the /etc/wpa_supplicant.conf file, bringing it to the form:

     ctrl_interface=/var/run/wpa_supplicant ctrl_interface_group=0 update_config=1

  2. run the wpa_supplicant program in daemon mode:

     $ sudo wpa_supplicant -Dwext -iwlan0 -c/etc/wpa_supplicant.conf -B

  3. Run the wpa_cli program:

     $ sudo wpa_cli

    and make sure it works by typing status at its invitation. You should see the answer wpa_state=INACTIVE .

  4. Use the scan and scan_results to scan for available wireless networks:

     > scan OK <3>CTRL-EVENT-SCAN-RESULTS > scan_results bssid / frequency / signal level / flags / ssid 00:00:00:00:00:00 2462 -49 [WPA2-PSK-CCMP][ESS] MYSSID 11:11:11:11:11:11 2437 -64 [WPA2-PSK-CCMP][ESS] ANOTHERSSID

  5. add the selected bssid ( 00:00:00:00:00:00 for MYSSID ) and pin (which you know, for example: 12345678 ):

     > wps_reg 00:00:00:00:00:00 12345678

    you should get the answer "ok". wait a few seconds while wpa_supplicant contacts the router, holds association and key negotiation . if you see the message CTRL-EVENT-CONNECTED , then the pin is accepted and the association is successful. at the moment you can run (in a different terminal)

     $ sudo dhclient wlan0

    to verify that the dhcpd in the router is functioning normally, and you can get from it the ip-address for the wlan0 interface.

    Go back to the running wpa_cli program and enter the save command, which should return "ok" and save the new settings in the /etc/wpa_supplicant.conf file.

  6. check these settings, and if everything is in order, you should see in the description of the new network a line starting with psk . this will be the generated key.

then it will be possible to connect to the same router in the “usual” way: from the command line, from gui - “wrappers” around the network manager , etc.
