Upstream sync speed extremely slow on BT infinity 2 - 80% speed drop

[tkei]

Same issue with my Fibre BB as well. For months happily at 10-12 mbps upload speed but in the last 6-8 weeks my upload speed has fallen off a cliff to be between 900kbps to 1.8mbps. I've rung BT 8 times and had openreach out to my home to investigate and nothing is resolved.  

The same old story from BT is upload sync speed is not guaranteed, but nothing has changed in my home to cause the sync speed to drop dramtically.  Because download is fine I'm being quoted £320 to leave the BT service. 

Peronsally I think BT are putting caps on certain customers BB that utilise more upload bandwidth than others. I know, first world problems, but my teenage son can't play his online games with his mates due to this poor upload speed. 

Any help apprecited - I've trie to get BT to get openreach out to the green cabinet and the exchange with no joy. Details below:

I moved your post to start your own thread so replies will not get confused with previous post originator

connection time only 36 mins was that a manual reset or router dropping connection?

 Thank you for your help. 17070 some slight noise on the line. 

With the uptime, yes I did a restart within the hub as the upstrem was at 976kbps, after my HH restarted itself 3 times over today.

I should also add that after some restarts I have seen speeds of 11mbps, however this doesn't last long and the homehub will restart the connection and this will normally drop to be between 1-2mbps.

Getting over 2 mbps is rare in the last 8 weeks or so.

If you are having that many resets I am surprised your down speed is as high and well within estimated range. Have you tried using the test socket with a filter to see if that helps stability and improves connection.  If you still get noise on quiet line test when using test socket then need to report phone fault to 151. 

When using test socket you need to check that there is no dial tone at any extension socket

Hi @tkei,

I would agree with @imjolly if you are getting noise on the line, this would indicate a fault with the telephone line. As you've already had an engineer out previously, I'd be happy to take a look at this for you and run a few checks on your line. 

Please can you send me in your details using the "Contact The Mods" link found in my profile?

Thanks

Thanks PaddyB, have sent the request

Removed the openreach box and plugged in an ADSL filter with the broadband - so effectively had no phone. 

The broradband upstream when to 15.8mbps straight away doing this - so I thought I'd live without my house phone connected with this. 

Come home today. Broadband router automatically restarted the connection and now back down to 2.5mbps upstream. Downstream is fine. 

Any help again appreciated.

If you have filter in test socket can you connect phone to phone side of filter and try quiet line test. Can you also check that there is no dial tone at any extension socket whether in use or not

[tkei]

When I take off the open reach box I do not have a test socket, but last night just plugged the ADSL filter into the main socket.
Have now plugged in the phone into the ADSL filter, same as before in terms of some very slight noise but nothing major.

Now have plugged back in the open reach and connected the BB cable and phone. Upstream has improved again:
Downstream sync speed:52.83 Mbps
Upstream sync speed:8.47 Mbps

Is this really normal that upload speeds can vary so much in the space of 24 hours, from 1.5mbps to 15.87mbsp, then to 2.87mbps and now 8.47mbps?
