I recently installed fedora 27 on my hp pavilion laptop. It was all working fine, but recently when I restarted my fedora, my wifi option was not working. I searched in network manager but it shows ''no wifi adapter found". I searched on the internet but not much help was available. Please help me in this matter.

Output of iwconfig:

wlo1      IEEE 802.11  ESSID:off/any  
          Mode:Managed  Access Point: Not-Associated   Tx-Power=0 dBm

This worked for me. I have a broadcom card though. Try replacing broadcom with realtek.

sudo dnf install -y https://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-27.noarch.rpm https://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-27.noarch.rpm sudo dnf install -y broadcom-wl kernel-devel sudo akmods --force --kerneluname -r--akmod wl sudo modprobe -a wl

I hope this helps.

Hi, Im a little too new to this and was wonderign why the uname -r is not in red. Up until that poin I tried it all and worked, but when I get there it tells me it "Could not find the files needed to compile modules for uname"

What am I doing wrong?

Welcome to ask.fedora! Try booting from a LiveUSB and see if it finds your WiFi. If it does, we can try to find out why your installed system doesn't. If not, it's hardware.
