I'm trying to reuse an old Asus EEE "a-la-RaspberryPi", as a small, single task unit. Since I am familiar with Fedora, I have installed Fedora 27 on it via VNC (the default graphical installer is too big for the EEE screen), but I did not install any desktop environment (I don't need it, plus even LXDE would have required more disk space than the entire size of the EEE).

During the installation I was able to connect to the Internet wirelessly (after having configured from the installer the SSID and PWD for my home network).

However, with the installed system, I am not:

[mac@octoserver ~]$ nmcli
enp3s0: connected to enp3s0
    "Qualcomm Atheros Attansic L2 Fast Ethernet"
    ethernet (atl2), 00:1F:C6:ED:3B:D9, hw, mtu 1500
    ip4 default
    inet4 192.168.0.131/24
    inet6 fe80::26b6:a207:c3f7:8c89/64

lo: unmanaged
    "lo"
    loopback (unknown), 00:00:00:00:00:00, sw, mtu 65536

wlp1s0: unmanaged
    "Qualcomm Atheros AR242x / AR542x Wireless Network Adapter (PCI-Express) (AW-GE780 802.11bg Wireless Mini PCIe Card)"
    wifi (ath5k), 00:15:AF:92:4E:2E, plugin missing, hw, mtu 1500

DNS configuration:
    servers: 192.168.0.1
    interface: enp3s0

The plugin missing is in bright red in the console, but I haven't been able to google or dnf anything up on what that is supposed to be... ath5k seems to be an enabled module in my kernel, and I could not find any "plugin" package for nmcli in the repos...

Also confusing for me is the following:

[mac@octoserver ~]$ nmcli radio wifi
enabled
[mac@octoserver ~]$ nmcli device wifi list
[mac@octoserver ~]$ 

The radio [of a device, I guess] is ON but there is no device?!

Any idea on what is going on?

    I'm having the same issue with Centos7 fresh installed. I tried dnf install NetworkManager-wifi but dnf is not installed. The installer was able to connect to wifi. Is there another way or do I need to connect via Ethernet and install? Commented Sep 8, 2018 at 19:15

You are probably missing the NetworkManager-wifi package.

# dnf install NetworkManager-wifi

To apply changes, restart NetworkManager.service:

# systemctl restart NetworkManager

  • Installing this caused NetworkManager to break with error "dependency". Whatever that means

  • I get an error because I'm not connected to wifi

On CentOS 7, the package manager is yum. Simply replace dnf with yum:

$ sudo yum install NetworkManager-wifi
