During the Anaconda installation of Fedora 23 Server (minimal install), my onboard WiFi card was detected and I was able to connect to my home wireless network and even enable network time. After the installation finished and the computer booted into the OS, the WiFi configuration is now gone.

The WiFi card appears in the output of lspci, but not in the output of ifconfig (only Ethernet and loopback show up there).

What's the next step here? I'm planning on this being a headless server, so I don't have a GUI or any graphical apps installed, just the command line.

What is the output of lspci -v and lspci -n of your WiFi card?
Looks like a driver is missing.

Because Minimal Install doesn't install NetworkManager-wifi and wpa_supplicant packages. Install these package with DNF, sudo dnf install NetworkManager-wifi wpa_supplicant or if you are offline, then grab the .rpm packages from other computer that has internet connection, copy those packages to your computer and install them with RPM or DNF.

Ah, that would explain it! Okay, so I downloaded those packages on another computer, copied them over via a USB drive, and tried to install one of them, but it's still not working because dnf is expecting an Internet connection. I'll post the output in the next comment because there's a 500 character limit.

Here's the output:

[root@localhost sdb1]# dnf install NetworkManager-1.0.10-2.fc23.x86_64.rpm
Error: Failed to synchronize cache for repo 'fedora' from '': Cannot prepare internal mirrorlist: Curl error (6): Couldn't resolve host name for [Could not resolve host:]

How do I tell dnf to just install the package? I tried rpm but it doesn't work.
