Slow Download Speed But Fast Upload Speed

Dkellz — Mon, 21 Dec 2020 09:30:03 GMT

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/2062450/highlight/true 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

https://www.speedtest.btwholesale.com/

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?

Re: Slow Download Speed But Fast Upload Speed

Dkellz — Mon, 21 Dec 2020 11:12:30 GMT

Sorry these tests were wired.

Here's the results of the adsl test too.

imjolly — Mon, 21 Dec 2020 12:17:28 GMT

do you use powerline adapters?

Re: Slow Download Speed But Fast Upload Speed

Dkellz — Mon, 21 Dec 2020 12:24:11 GMT

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.

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

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.

Did you also try using test socket with the new filter just in case that does make a difference by eliminating faceplate and any extension wiring

Hi Imjolly

I'm not sure what you meant by using test socket with the new filter?

Do you mean plugging the broadband into another phone socket in the property?

We only have the one phone point here.

imjolly — Mon, 21 Dec 2020 17:41:15 GMT

Test socket is behind the master socket faceplate

which master do you have

Hi Imjolly

I don't think think my parents have any of those face plates. They have a bog standard telephone plate...a brass one.

This is the one that was here when they bought the property almost 5 years ago.

The problem i'm having is very similar to what this person was having in this thread:- https://community.bt.com/t5/BT-Fibre-broadband/Slow-Download-Speed-but-fast-Upload-speed/td-p/2062450/highlight/true His issue was solved by being moved to a SVLAN which happened after speaking to a BT Moderator. I'm getting more convinced that the issue lies between the BT Exchange to outside of my parents property.

imjolly — Mon, 21 Dec 2020 17:54:21 GMT

So that is the only socket in the home and if so then it must be where the openreach cable enters the property?

Re: Slow Download Speed But Fast Upload Speed

Dkellz — Mon, 21 Dec 2020 17:56:36 GMT

Unfortunately that's the only socket we have here. I asked my dad if there are any other sockets around the home, he said no.

Quick update on this issue.

We called BT again this morning and asked to speak to someone technical. I explained all the troubleshooting steps i'd been advised to try on the BT Forum.

I said i was convinced that the issue was outside the property, not inside. The BT guy said it seems like a fault on the line, he said the engineer BT had booked in for the 29th wouldn't have been able to resolve the issue. We now have an engineer booked in for tomorrow morning 🙂

I'll ask him if it's possible to change the faceplate too when he arrives.

Thanks for all the help given on forum as this helped to narrow down the fault and at least rule out an issue in the property.

Thanks

Dave

When I spoke to BT yesterday they reckon there was a fault on my line, i'm not sure why they couldn't have looked more into this last Saturday when i called them after installing the new router and it made no difference. It seems like once i'd made them aware of the troubleshooting steps i had taken, it was only then that they seemed to look more into it their end and then come back and say there was a fault on the line.

The engineer was booked in for between 8am - 1pm today. The BT engineer never came to my property but when i checked online earlier, my parent's BT account indicated that the engineer visit had been completed and the ETA for a fix was 24/12/2020.

I'll reboot my router when i get a chance but BT did say to me yesterday that it might take up to 24 hours for the fix to take effect.
