I am able to connect to a wireless network using nm-applet when running it in lightdm, however, it does not work in an openBox session that I start as myself (a user started X Session), but am not able to do so using nmcli.

I am running nmcli using sudo. After 90 seconds, I get a time out message. What could be wrong?

This is the configuration I must use - http://www.depts.ttu.edu/ithelpcentral/solutions/wireless/

Tested in Ubuntu 16.04 LTS

In case the wireless interface is already connected to some other AP, first disconnect it using

nmcli con down <AP name>

Example: Supposing interface is already connected to 'PreviousAP', then disconnect it using

nmcli con down PreviousAP

Now for Connecting to new AP

Considering you know the AP name and password.

nmcli device wifi connect <AP name> password <password>

Example: AP name : Connect-to-this

WPA/WPA2 PSK : iampassword123

nmcli device wifi connect Connect-to-this password iampassword123

This will automatically create a file in /etc/NetworkManager/system-connections/ with the APname, which will contain the configuration.

ls /etc/NetworkManager/system-connections/Connect-to-this

To turn on WiFi

sudo rfkill unblock wifi

nmcli networking on

To list WiFi Networks

nmcli connection show

Output should be something like this

NAME                      UUID                                   TYPE              TIMESTAMP-REAL

ncmli allows you to connect via The UUID or ID (NAME, SSID)

Usage :

 nmcli connection { COMMAND | help }

   COMMAND := { list | status | up | down | delete }



   list [id <id> | uuid <id>]

   status [id <id> | uuid <id> | path <path>]

   up id <id> | uuid <id> [iface <iface>] [ap <BSSID>] [--nowait] [--timeout <timeout>]

   down id <id> | uuid <id>

   delete id <id> | uuid <id>

Example Usage in this case

• 
  

  Connect :

  
  
  

  nmcli c up uuid cd79a7a1-1cf4-49c3-ad58-21ab17d1ba05
  
  

  
  
  

  or

  
  
  

  nmcli c up id Rishbh-Q1000
  
  

  
  


• 
  

  Connect on specific wlan interface :

  
  
  

  nmcli c up id Rishbh-Q1000 iface wlan1
