Extreme reduction of download tomdevices

Have got 900 mbps fibre broadband.  BT app speed test says 925 to hub but 110 to device . Why the huge difference please.

@grumpygrandad 

Your device may not be cable of the full speed, what device are you testing it with?

You would not get the full speed on Wi-Fi, the speeds quoted are for a fast PC connected using an Ethernet cable.

The reasoning behind a faster connection, is that it can be shared by lots of people within the household, not for one user to get the full speed.

Here is a copy of a post from a moderator.

"I think for the first time ever we are in a situation whereby the speed you can now get through Full Fibre outperforms the capabilities of many devices.  

The Smart hub 2 does not come with Wi-Fi 6 but this is something we are looking to include in our next generation of Hub.  I don't have any info as to when we will launch a new router by Wi-Fi 6 will bring some improvement.

As an example of what I mean in terms of devices not being able to support the full breadth of speed available on Full Fibre 900, take a look at the table below.  This is just for a couple of Apple Smart Phones and Tablets along with  popular Samsung models,

 

Apple (Smartphones) Dualband (2.4 & 5Ghz) Theoretical Max speed on 2.4Ghz connection Theoretical Max speed on 5Ghz connection
IPHONE SE Yes 60mbps 300mbps
IPHONE SE 2020 Yes 135mbps

600mbps

 

Samsung (Smartphones) Dualband (2.4 & 5Ghz) Theoretical Max speed on 2.4Ghz connection Theoretical Max speed on 5Ghz connection
galaxy-s10e Yes 135mbps 600mbps
galaxy-s10-5g Yes 135mbps 600mbps

 

Apple (Tablets) Dualband (2.4 & 5Ghz) Theoretical Max speed on 2.4Ghz connection Theoretical Max speed on 5Ghz connection
IPAD pro 3rd gen (Nov 2018) Yes 135mbps 600mbps
IPAD pro 4th gen (March 2020) Yes 135mbps 600mbps

 

Samsung (Tablet) Dualband (2.4 & 5Ghz) Theoretical Max speed on 2.4Ghz connection Theoretical Max speed on 5Ghz connection
galaxy-tab-s5e Yes 100mbps 300mbps
galaxy-tab-s6 Yes 60mbps 600mbps

 

Ethernet should ensure you get the maximum possible speed but I also appreciate that connecting this way is not always possible"
