Slow Download Speed But Fast Upload Speed

[Dkellz]

Hi all

I've recently moved back in with my parents (November) who have BT broadband.  When i first moved in i ran a speed test and they were getting download speeds around 46mbs and uploads around 19mns if i remember rightly.

We've noticed over the last few weeks that we've been having issues with the broadband so we called up BT last week, they said it could be the router and sent out a new router which arrived on Saturday 19th  December.  

I've set up the new router but it made no difference.  I've noticed that our download speed is faster first thing in the morning (yesterday morning it was 34mbs download and 19 mbs upload speed ) after rebooting the router but it drops drastically as the day wears on so by mid day yesterday our download speed was barely over 6mbs. 

This morning it was 20mbs (our guaranteed speed is 48mbs) and upload was 19Mbs.   We called BT yesterday and they said the earliest they can get an engineer to us is December 29th.

I've just been looking on the BT form and found this article...https://community.bt.com/t5/BT-Fibre-broadband/Slow-Download-Speed-but-fast-Upload-speed/td-p/206245...  This is exactly the same issue that we are having, i just wondered if it's possible for one of the mods to help?

all speeds quoted by BT are connection speeds not download speeds and you are currently getting 63mb down speed which is above handback

can you post dslchecker results please  remember delete number  https://www.broadbandchecker.btwholesale.com/#/ADSL

can you run btspeedtester with ethernet connection direct to hub (no powerline adapter) and post results

if that has problems then try  https://fast.com/

Hi imjolly

Thanks for getting back to me, here's the results of the speed tests.

I'm just trying to reduce the size of the adsl checker as it exceeds the file size limit.

I'll send this one over once i've got it under the file size limit.

Are those speed tests via wired or wireless?

[Dkellz]

Sorry these tests were wired.

Here's the results of the adsl test too.

[imjolly]

do you use powerline adapters?

[Dkellz]

My parents use two of them but i removed them when i did the speed test.

They've been using them for some time and it's not been an issue before as far as i know.

[imjolly]

if you just received a new SH2 did you turn off smart setup?

there are posts already where speed problems were down to using powerline adapters

[Dkellz]

I've just gone into the Smart Hub Manager, Smart Setup is grey, i'm assuming this isn't active?

I've just gone into Smart Setup and it's set to off.

I've removed both powerline adaptors and powered the router back on.

I ordered a new adsl filter from Amazon yesterday, I've just installed the new adsl filter and unfortunately it's not made any difference.  My download speed is barely over 5mbs now.

I'm not sure what more i can do really, i've swapped back to the old BT router i was using up until Saturday 19th December and i've got the same issue.  I've removed the powerline adaptors and this hasn't made any difference .  I've just installed a new adsl filter but again it's made no difference.
