After installing Fedora 23 Linux, I had to do a few steps to get my wifi adapter working, which is a Broadcom BCM43228 card. It turns out that these steps have to be repeated each time after a kernel update.
Those steps are automated in this script, which can be executed as the root user:
su - # or `sudo su -`, depending on your Linux distro dnf upgrade && reboot # to avoid an error while building the driver (see Step 2 in the long version) su - cd /var/tmp wget https://gist.github.com/ouyi/d7768d21fa9dfc6d27b0/raw/250aea83cc7b09d99c01fe41e50249c9702082e7/fedora23_broadcom_wl.sh chmod +x ./fedora23_broadcom_wl.sh ./fedora23_broadcom_wl.sh
After that I was able to onnect to my Wi-Fi network via the NetworkManager.
The solution basically consists of three steps:
Download the driver
BCM4311 BCM4311 BCM4311 BCM4312 BCM4313 BCM4321 BCM4321 BCM4321 BCM4321 BCM4322 BCM4322 BCM4322 BCM43142 BCM43224 BCM43225 BCM43227 BCM43228 BCM4331 BCM4360 BCM4352
Build and install the driver
dnf upgradeand reboot first, to avoid the following error while building the driver:
error: make: *** /lib/modules/4.2.3-300.fc23.x86_64/build: No such file or directory. Stop.
Load the driver
depmod -awas needed to make the newly installed driver available to the modprobe command and to avoid missing dependency issues like the following:

The solution is based on this page.
This one does not work for me.
Update 21st Oct 2016
Unfortunately, the recent kernel update to 4.7.7 broke the above method. The build process fails with this message:
cfg80211 api is prefered for this kernel version ieee80211_BAND_2ghz undeclared
Selecting the previous kernel version (4.5.6 in my case) from the boot menu allows me to still work with wifi.
