This post is quite old, so it's probably already to late but I can try to help. I'm not sure what network manager Fedora uses, but you could try to narrow the issue down. Here are the steps I would take if I were you:
- Check system logs with
journalctl -e
and see if there's anything strange there - Confirm that I have a local IP address with
ip addr
(next to your network device name, should be something like wlpxxx for Wi-Fi) - Try to ping a popular server, e.g.
ping 8.8.8.8
for Google DNS - Try to check whether DNS works with
dig google.com
- Check what route my packets take on the way to the server with
tracepath 8.8.8.8
- If any of these are out of the ordinary, I'd try to google the error and see what else can be done
If you have any questions, feel free to ask. I'd be happy to help
