Hey everyone, I just installed Fedora with the KDE desktop environment yesterday and was able to connect to my home WiFi with no issues initially. However, after switching back from Windows, I can't find any visible WiFi networks anymore. The options menu shows that my home network is still saved, and I was just connected to it about 10 minutes before. I checked using 'ip link show' and only see the loopback (LO) and a downed ethernet connection (esp12s0). So, it seems like the WiFi interface isn't being detected at all. I haven't made any updates since the install, and WiFi works perfectly well in Windows. Any ideas on what might be going wrong?

You should definitely try running `iwctl device list` to see if your Wi-Fi interfaces are detected. If nothing shows up, that likely means your Wi-Fi card isn’t being recognized. As a temporary fix, you could connect using an Ethernet cable or a Wi-Fi dongle and check for any necessary drivers, especially if you have Broadcom or Realtek hardware, since those often need non-free drivers.
You might want to double-check if Windows' fast boot feature is enabled; it can cause issues with networking in a dual boot setup. Many guides recommend turning off fast boot for a smoother experience.
How are you switching between Fedora and Windows? Is it a dual boot setup or are you using a virtual machine? You might want to run `sudo dmesg` to check the logs for any Wi-Fi related errors that might give us a clue.
Just a heads up, dual boot setups can have time-related issues because Windows and Linux treat time differently. You might want to follow some tweaks to fix that, just in case it's affecting your networking!
When you switch back to Fedora, make sure to also restart the NetworkManager service; sometimes it needs a kick to recognize changes after switching OS.
