I just reinstalled ArchLinux on my Thinkpad. I am a bit puzzled that the network-manager-applet only supports WEP encryption for wifi networks.

network-manager-applet

I already installed wpa_supplicant and wireless_tools as suggested elsewhere on the internet.

I'm running ArchLinux with kernel 4.8.13-1-ARCH and the classic Mate Desktop environment in GTK-2 version.

How to enable WPA and WPA2 for the Network Manager Applet?

  • after installing wpa_supplicant you have restart the service and the applet?

  • Yes. Did a full system reboot meanwhile.

  • I can only give you a link, because I have no arch <wiki.archlinux.org/index.php/WPA_supplicant

  • I can't find anything specific about network-manager-applet on that wiki page. wpa-supplicant is installed and enabled.

Ok I was confusing two things: (1) creating new networks with the network-manager-applet only supports unencrypted or WEP encryption, as shown in the screenshot above. (2) Connecting to WPA secured wi-fi networks works with wireless_tools and wpa_supplicant installed.

However, it did not work in my case because I was using the network-manager-applet which was designed for GNOME on a MATE desktop environment. Here is the important snippet from the Arch Wiki:

Troubleshooting

No prompt for password of secured Wi-Fi networks

When trying to connect to a secured Wi-Fi network, no prompt for a password is shown and no connection is established. This happens when no keyring package is installed. An easy solution is to install gnome-keyring. If you want the passwords to be stored in encrypted form, follow GNOME Keyring to set up the gnome-keyring-daemon.

My mate installation was lacking a keyring. Installing gnome-keyring fixed the issue.

$ sudo pacman -S gnome-keyring

I am now able to use the WPA secured wi-fi networks again.

nm-applet creates an Ad-hoc connection through that menu.

You might want to create a hotspot connection, and you can do that through "Edit Connections..." nm-applet Editing wifi-test

You will then be able to select WPA & WPA2 Personal on Wi-Fi Security tab.
