Slow speeds on fibre optic

[LKShell]

Had super fibre optic installed 16 days ago.

Sky test says I'm getting 501mbps however the devices themselves aren't getting anywhere near that.

Noticed things were not loading any quicker than before when I had standard broadband so ran speed tests-download speeds as follows;

WiFi=186-202mbps depending on time of day.

Wired via Ethernet and WiFi extenders=34-41mbps 

We have two devices that are wired (a PC and an Xbox) both continue to 'lag' and can take a day to download games.

I have upgraded the Ethernet cables from cat5 to cat 8, still no difference and getting the same speeds.

Router is located in the best location and WiFi extenders are the most suitable type as determined by the sky engineer who installed the fiber optic 16 days ago. 

Am I missing something? Does anyone else have this issue since moving over to fibre?

Those both sound entirely plausible for 500Mbs arriving at the Hub.  WiFi is dependent on building fabric, local conditions and devices, while Powerline throughput depends on the capability of the adapters and the nature of the mains cabling.

Only actual ethernet cable between gigabit hardware is guaranteed to deliver the bandwidth of the internet connection.

So are you saying that upgrading to fibre optic is pointless? 

Wired speed remains unchanged and this is not what I anticipated or expected from such an upgrade

FTTP is largely intended to deliver 'enough' bandwidth to many devices.  Our 500Mbs BT FTTP 'tests' at between 480Mbs on an ethernet PC and 40 Mbs on a rather elderly phone.

If the bottleneck is your household mains cabling (which was never intended to carry data) then that remains a problem no matter how fast the external connection is.

Is any device on a direct ethernet connection to the Hub (and known to have a gigabit ethernet chipset)?

That's the place to get an accurate assessment of internet speed.

As is customary per installation of fibre optic, the fibre optic cable has been installed via Open reach from the telegraph pole (no means to run underground), to a junction box on the outside of my property. A smaller cable is then ran inside to the ONT. A cable then runs from this directly to my router. Assuming the installation was done correctly, which I'm guessing it was as SKY say I'm getting 501mbps to my router, then I'd say the mains cabling should have the required capacity. 

The extenders and Ethernet cables were checked to be of suitable quality for the delivery of fibre optic. 

I guess my main question is has anyone else had fibre installed and getting the same wired download speeds as they were before when on a standard broadband. If so what did they change to improve speeds on their wired devices?

I'm referring to in-wall mains cabling running between Powerline network adapters: that's a huge potential bottleneck.

@LKShell 

If you are running ethernet cable to wireless rather than Powerline 'extenders' then the bottleneck is likely to be a combination of local WiFi conditions and the inherent capability of the hardware units: again increasing the external speed cannot make much impact, and neither can the grade of cable (Cat5e is easily capable of gigabit transfer)

[LKShell]

Ah okay, so all WiFi extenders are plugged into main sockets and the mains electrical system in my house is only a few years old as had the place rewired when I bought the place.

@LKShell 

Doesn't really make a difference: three cable parallel mains cabling cannot replicate 8 core twisted pair in ethernet cable.

What you have might be Powerline (where some of the data transit is over mains cable) or WiFi - only 'extenders' (which would be better described as 'relays')

Neither is ideal for reliable network transfer. 

If possible, you need to check that the broadband itself is delivering the promised speed, by using ethernet to link a device directly to the Sky Hub: at least then you know the issue is elsewhere.
