Fedora 23 with a Belkin USB wifi adapter:

Bus 001 Device 002: ID 050d:945a Belkin Components F7D1101 v1 Basic Wireless Adapter [Realtek RTL8188SU]

This device is nothing fancy, but has been working flawlessly. I was downloading/applying the latest F23 updates a few days ago, and upon reboot, the wifi was bye-bye.

lsmod | grep wifi showed nothing.

I have confirmed that my USB wifi is working fine. I can manually get the wifi interface up with the following commands:

modprobe rtlwifi
lsmod | grep wifi

systemctl status NetworkManager
systemctl disable NetworkManager
systemctl stop NetworkManager

ifconfig wlp0s26f7u2 up
iwlist wlp0s26f7u2 scan
iwconfig wlp0s26f7u2 essid MY_NETWORK
dhclient wlp0s26f7u2

systemctl enable NetworkManager
systemctl start NetworkManager

What has happened so that this wifi interface does not come up automatically upon boot?

That happens to me once. What happened that time was that wlan interface change the name, instead of wlp2s0, now is wlp6s0. Also, can you tell what package you update to know what effect has on the networking?

I do not know how to determine which particular update broke my wifi networking. If you or anyone else has a good idea on how to do so, I would be very interested to read it! :)

Latest system updates (including NetworkManager-wifi) as of April 30 2016 have resolved this issue.

USB wifi now initializes automatically upon boot.

Thank you, Fedora team! :)
