Hello, I’m running into an issue that I can’t quite figure out. I have Fedora 41 with KDE, with just the basics installed via everything, and I’m connected to my 5GHz WiFi without any issues. But when I connect from my phone to some service hosted on the PC, like Jellyfin or an FTP server, I lose internet connection on the PC right away. Of course, my phone also loses connection to the host. If I disconnect and reconnect to the network, the internet works fine again. I’ve tried troubleshooting network stuff, but no luck so far. Anyone else experienced this, or have any idea where I should look to investigate further? Thanks a lot!
You’ve watched the system journal via journalctl -f in a CLI ?
Any messages thrown in there when you connect your phone and the network drops?
This is what journalctl -f throwed, when I connected to Jellyfin and freezed everything.

And from here, a few searches sent me to the MTU field, but still not working.
After some other searches, I found a solution that, while it works, I’m not sure if it’s the correct way. I changed the wifi backend to iwd.
Thanks for the reply.
