@Richardp13 you took the stats just after the hub restarted so they dont tell us much other than you have a long line which is connecting at 35Mb/s down and 7Mb/s up which is pretty good for its length as the noise margin is 3.4dB which indicates low noise issues.
Over an Ethernet connection you should see speeds of around 32Mb/s down and 6.5Mb/s up. Over wif speeds will be whatever depending on the layout and construction of your home. If you use a normal wifi booster/extender thst can only deliver roughly 50% of the speed of the connection it has back to the hub. You could try improving the back haul that unit has by using an ethernet cable assuming it has a rj45 connection. Alternatively moving the extender and hub to improve the wifi signal connecting the two can help. A very useful app when optimising wifi networks is an app called Wifi Swetspots installed onto a smartphone which tells you the true wifi speed between the phone and the router.
With homes with more than two levels you often need better kit than a simple router and booster can provide my own included. You can do as I did and buy a whole homecwifi system, mine has 3 satellite units, turn off the Sky hub;s wifi and use that. Alternatively you could pay extra Sky's own Wifi Max kit which is similar - note it doesnt work if you have Sky Q boxes - which gives you a newer hub and up to 3 extenders assuming a Sky engineer agrees you need them. A third option is something called powerline networking which uses your mains wiring to carry the signal to the top floor where it connected to your current extender.
