Flint 3 MLO breaks KDE Connect

[marwis]

I have KDE Connect between my phone (Samsung S25U) and tablet (Pixel).

When phone is connected via MLO Wi-Fi the KDE Connect is unable to connect/discover other device.

I think it uses multicast for discovery but might be wrong.

I have very basic Flint 3 setup with HW acceleration disabled and latest firmware.

Are both devices on the same network?
MLO needs to be the only available band in Linux, as far as I tested it.

Yes, both were on MLO. It also seems like ping does not work except occasionally when phone is on MLO.

You can consider SSHing into the router and running the following commands to see if they fix the issue.
