@Mjvern when running speed tests you can get abnormal results if too close to the hub due the way the aerials are designed but you should be seeing WiFi speeds up to 900Mb/s is between 1 to 2 metres from the unit assuming it is out in the open and ideally around waist height to avoid obstructions. Speedscwill drop if the signal has to pass through walls or similar and is entirely blocked by even a thin sheet of metal foil.
The ethernet speedscare odd as while 90Mb/s is explicable 110Mb/s is not. Ethernet ports on PCs are often limited to 100Mb//s so can only support throughput of 90Mb/s after allowing for network overheads. Ports have to be Gigabit capable to support higher speeds. Check the settings on the PC for the port
You say you have only just got the new service it has been noticed thst it takes a few hours before Sky pick up the new connection and allow the full throughput rather than a restricted bandwidth thst appears to be made available for testing. If you still have the same issue this morning call Sky and report it.
