@Lucy200095 if you mean speed to a device connected by wifi then that is not something Sky guarantee as the speed you get depends on the layout and type of construction in your home. While 500Mb/s is achievable in the same area as your hub move a few rooms away then speeds inevitably drop although paying for extra wifi extenders can help. For gaming it is advised not to use WiFi but instead use an Ethernet cable not so much for bandwidth although that should help but more to get lower latency and better stability..
If however you suspect the issue is the broadband speed to your hub tgen run tge service checker as if Sky's daily tests show those speeds have dropped the system should offer further help.
