Wi-Fi speed not as quick as it should be

[bradbn]

I've just upgraded to gigafast broadband and the speed is not gigafast ! I was getting 340 on the speed test and I'm now getting 360, your data tells me I'm getting 664 ????? My neighbours on similar deals with by are getting 900, something is not right here and I'm not getting what I've upgraded to

I think there has been some misunderstanding. The gigafast package from Sky will not guarantee 900mbps over WiFi, the 900mbps figure is your line speed to the router. This can usually be obtained by an ethernet connected device, but often not a WiFi connected device. There is very little requirement for a single WiFi client to achieve anything over 100mbps, instead the bandwidth is shared across many devices.
