@StuartBrodie So looks like you are on the FF900 package, depending on the sky Hub and how good the device you are speed testing with the only true test is all wireless off and an Ethernet connected device that can get the 900Mb/s download, then test that way first, wireless wi-fi testing and all shared network path can be difficult to pin down the max speed!
500 to 600Mb/s is the area that a sky Broadband Hub will be able to see and push the hub up to!
