1. MAC cloning in home web? Any benefits from it? When I clicked in router settings to clone from connected device, I lost my internet connection.

  2. IP and MAC banding in home web? Again, any benefits?

  3. Can’t ping ipv6.google.com with 6to4 tunnel, any solutions? I will provide more data if necessary. (Request timed out)

  4. All my devices are new, so UPnP is safe for me then?

ISP: UPC Poland Router: Tp-Link

Thanks for the anwsers!
