I have changed the wpa_supplicant.conf file on my Raspberry Pi 3 (running Raspbian Lite) to the proper SSID and password of our WPA2 WiFi, and it shows the proper SSID when running iwconfig. However:

  • When I run nmcli general status, it says the Raspberry Pi is disconnected.
  • The Raspberry Pi is not detected on our router's configuration page.
  • The /etc/network/interfaces file only contains comments and a reference to an empty source directory (interfaces.d), unlike how I've typically seen the file online.

The /etc/wpa_supplicant/wpa_supplicant.conf file currently looks like this (with the SSID and password replaced by the proper information):

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
country=US

network={
    ssid="wifi_name"
    psk="wifi_password"
}

How could I establish a functioning connection?

What OS are you running?

nmcli is a command-line tool for controlling NetworkManager which is NOT installed or used by Raspbian. NetworkManager does not use wpa_supplicant.conf

See How to set up networking/WiFi for setting up networking on Raspbian.

  • I'm running Raspbian Lite and have installed network manager, but from what you're saying, it sounds as if nmcli may produce unreliable results. My Raspberry Pi was successful when I pinged to various sites and my local gateway, so why do you think it's not shown as an "attached device" to my router? I have already followed the steps in your link. – Matthew Taylor Jun 24 '18 at 13:09
  • You have 2 incompatible network managers installed NetworkManager and dhcpcd (the standard). The link describes configuring dhcpcd on Raspbian; if you want to use NetworkManager you will have to configure it, but this is normally done by the GUI. Don't expect any help for NetworkManager on this site - try a Ubuntu forum. – Milliways Jun 25 '18 at 00:29
  • I ended up switching the OS from Raspbian Lite to the full version of Raspbian, and that did the trick. Thanks for taking the time to help! – Matthew Taylor Jun 25 '18 at 00:50
