Slow upload speed

[#1]

Hi,

For the last couple of days or so my upload speed has been extremely slow, whereas the download speed seems OK.  I'm on unlimited fibre and my download speed has been around 37-38Mb since March 21 when I had it installed.  The upload speed has been around 9-10Mb, whereas the last couple of days it has been <1Mb, yesterday the speed test showed 0.25kb!!

Is there anything that can be done to test whether there is a fault externally?  I have rebooted my computer/router and tested with a wired connection, with no improvement.  From my point of view, nothing has changed.

Any help/suggestions would be much appreciated as I am not very technical. Thanks.

Good morning Caroline. That sounds strange, but there is little that can be done with regards to upload speeds, these are not guaranteed by ISPs.

Can you post a screenshot of the 'Advance Diagnostic' tab from here: https://speedtest.btwholesale.com/ , please?

Hi,

Thanks for getting back to me - I'm at work at the moment so I won't be able to do anything until I get back later tonight (sorry, weird working hours).

At least it's not painfully slow trying to post from here!

OK - I'm around until about 9PM, or back early in the morning.

Hi,

I'm not sure if this is what you want (Word file attached)?

That's what I wanted, thanks, but unfortunately, as they 'encountered a problem' with Advanced Diagnostic, it merely confirms your observations, without the additional information the full Advanced Diagnostic would supply. I can't say much more without the extra detail, but I find it strange - usually if there is a problem with speed, it is visible on the download, with the upload remaining constant.

I'm not going to be around much for the next couple of days, but if you could see if you could get the 'Advanced' it may help others if I don't pick it up - I'll still be around, but probably not during daylight hours.

BTW - if you could post direct to the topic, rather than as a Word file, it is easier to follow.

OK, thanks.  I tried to paste the screen shot directly but it didn't seem to accept it - having said that it is painfully slow trying to post anything from here.

How do I get the advanced diagnostics to work properly?  All I did was enter the phone number and click OK/run.  I didn't know what the other options meant.

I've got to go in to work again tomorrow so I probably won't see any replies until late again, so technically your hours probably match mine better than you think at the moment!

To 'paste' the screenshot directly into the reply, save it, then click the icon to the right of the  'smiley' one above the reply window and follow the prompts.As to the Advanced Diagnostic - you can't, it's a known problem on BT's side, but perseverance usually pays off.

I'm not working - just having a couple of days at the Blackpool Coach Rally. 😀

Hi @Polaris1 

I've just been running some tests on your line which aren't showing any obvious causes for the reduced upload speed. 

When you tried a wired connection was it direct to the router or through a network switch or a powerline adaptor etc?

Hi,

Thanks for the assistance, much appreciated.  I am using a desktop PC which has an Ethernet cable directly connected to my router.

I'm not sure if it is the right terminology, but someone else suggested going in to my settings, disabling the Ethernet adaptor(?) and re-enabling.  That made no difference.

As per John's previous request, I have also repeatedly tried the BT Speed test, but the Additional Diagnostics are still giving an error.  Is there anywhere else I can try to get the information from, bearing in mind I don't know what I'm looking for.

Thanks.

Hi Caroline, thanks for getting back to me, don't worry about the BT speed test, I can get the information we'd need from tests we've run from here for you. 

Do you have access to a different device you could run a speed test on such as a phone or tablet just so we can rule out the PC being the cause of the issue?

Hi Adam,

Normally the answer would be 'yes' as I would have my work laptop, but I had to leave that with the IT department on Friday to sort out some updates and an overheating issue/constantly running fan.  I will be able to try this, but not until Monday evening.  Sorry.

Is there anything else that I can try in the meantime?  What normally causes slow upload speeds?  It is really frustrating at the moment trying to do anything where I need to post or upload something, even an email with a small attachment is taking 2 or 3 minutes to send.

Thanks

Caroline

No worries, from experience issues with upload speed tend to be hardware or software related, if you've not already it would be worth making sure any security software you might have installed is up to date in the meantime.

Is there anything else that I can try in the meantime? 

Is there any other device connected that might be trying to do a backup to the 'cloud' e.g google drive ?

I have McAfee installed (auto updates) - I've just checked and it confirms I have the latest updates installed.
