[SOLVED] KDE Connect completely breaks internet during file transfer

I don't know what's the correlation between them, but every time I try to send a file over KDE Connect from another device, my internet connection stops working completely. Plasma doesn't even detect that the connection has stopped, it still shows that my wifi is still connected, no "Limited connection" warning or anything similar whatsoever. Reconnecting to the network fixes the issue.

I'm using a laptop and I'm connecting to the internet over wifi. The wifi module is a MediaTek RZ608 Wi-Fi 6E 80MHz.

I have no idea if this is an application issue or a driver/hardware issue so I hope I posted this on the right board.

Re: [SOLVED] KDE Connect completely breaks internet during file transfer

I just solved the problem myself and I'll be leaving some details for those who might be experiencing the same problem:

I decided to investigate the issue a bit further and found out that it wasn't restricted to just KDE Connect. Connecting to any local devices on the network by any means will halt my internet connection. I looked in the journald log when this happened and found that these were most likely related to the issue:

5/29/22 9:43 AM	wpa_supplicant	TDLS: Creating peer entry for c0:bd:c8:89:43:03
5/29/22 9:43 AM	wpa_supplicant	TDLS: Dialog Token in TPK M1 47
5/29/22 9:43 AM	wpa_supplicant	nl80211: kernel reports: key addition failed
5/29/22 9:43 AM	wpa_supplicant	TDLS: Failed to set TPK to the driver

So, having no idea how to deal with wpa_supplicant, I just made NetworkManager use iwd instead (see NetworkManager#Using_iwd_as_the_Wi-Fi_backend) and restarted NM. Everything works normally after that.

Probably not the best solution but it's the only one I could think of right now.
