Slow Download Speed

Go to solution

Hi all,

About 2 weeks ago my download speed dropped from over 40+ Mb to no more than 2Mb. I've tried all the usual methods, reset Hub, checked quiet line, swapped leads etc. All to no avail. I seem to be getting nowhere with the online 'help/call centre'. They report that the hub is recieving a full 70+Mb of data download, not what I'm getting though. I'm using a wired connection to the Hub on a pc, wireless is also less than 2Mb.BT Broadband 1.png

Any help gratefully recieved.

Do you experience the very slow speeds all the time or just at peak times?
Has an engineer been out yet to investigate the Openreach network?

You can see from your stats you do have a connection speed of 79mb Can you run btspeedtester again but this time run diagnostic test which follows and post the results. Must be with Ethernet and preferably with IE/Edge as others have given odd results Which exchange and cab are you on?

From the screenshot they’ve posted it looks like the further diagnostics has already been run but it failed to complete correctly. I’d too recommend IE/Edge if you aren’t using it already.

Thanks for the replies all.

I've ran the diagnostics again, this time with edge. Results below.

The speed is slow at all times of the day, although much worse in the evening when it can drop below 1Mb. I ran this test just before 9am (ethernet connected with virus/firewall off).

No engineer has been yet as the call centre claimed they could not send one as they do not detect a problem! Not the most useful tbh.

The further diagnostics will still not complete for some reason.

Something must have been actioned this afternoon while I was out.

My speeds are now back up to 60+Mb back to as they were a couple of weeks ago. Maybe an engineer has visited the local exchange/cabinet.

I'll monitor over the next few weeks, hopefully this is now sorted.

Thanks once again for any help offered.
