To cut the story short; I've had fiber for 3 weeks, and download speeds don't go over 4.7mb/s.
I contacted customer services, and they told me to wait 14 days after activation, as speeds will need to 'settle'. That has come and gone, and speeds are still the same. I contacted customer services again, and they said there's a problem with the exchange, and an engineer will be despatched to fix it, and it should be fixed by 6pm monday (01/10/18) which has also come and gone.
So, i contacted customer services again, and they said i have too many devices connected, and need to change wifi channel, or something along those lines. I tell them I use wired connection for my PC, not wifi, so it can't be that and that i tried several different cables, including the one that comes with the smart hub.
So, i'm at a loss.
Speed tests say I should be getting 40mb/s.
A couple of quick questions which should help you out.
Let us know and we can move onto other ideas.
post stats from your hub advanced settings then technical log information
enter phone number and post results remember delete number https://www.btwholesale.com/includes/adsl/main.html
run btspeedtester and then disgnostic test and post results must be done wired http://www.speedtest.btwholesale.com/
just another thought you are not getting bytes and bits mixed up https://community.bt.com/t5/BT-Fibre-broadband/Technical-Glossary/td-p/1434076#_TocBits
a cheap landline phone about £5 is the intial basic check to make sure you have a dial tone and to check for line noise which is bad for broadband it can save you being charged £129.99 for engineer callout so really good investmet
as you can see your download speed is 37.88 on 40mb connection speed I think you are confusing bits and bytes
what estimated speed range did you get from BT in the initial letter/email
you have 37mb connection speed you are confusing your bits and bytes did you read the link I posted which explains
Bits Vs Bytes. - When you run a speedtest, for example http://speedtest.btwholesale.com/ , the results will usually be in Megabits per Second (Mbps). However when you download/transfer a file or program you will notice the Transfer rate will be in Megabytes per Second (MBps).
So if you have a download throughput speed of ~56 Mbps then a transfer rate of 7 Megabytes per Second (MBps) is the same as saying 56 Megabits per Second (Mbps).
The same applies for Kilobits per Second (Kbps) and Kilobytes per Second (KBps).
Easy way to remember is that there are 8Bits in 1 Byte.
5 MegaBytes a second would be about right for your connection speed of 37.88 Megabits a second.
I think you may possibly be getting confused. What are you using to measure you download speed?
What does the BT Wholesale Performance website show?
Example of your speed below.
