Strange and constant connection lost

Hi,

Happy New Year, y'all!

I've searched on several forums, but I've not seen a similar case to this one.
My Kodi, running on LibreELEC, loses access to internet.
No addon works, no library update, nothing.
I can see the connection as ready on the setting menu, but it does not work.

I could upload the log before the error happened (it happens in the first minute Kodi is on). You can find it here: Ubuntu Pastebin

Let me know if there's anything else I can provide you with to be able to help me.

Thank you so much in advance...
