Broadband speed gone very slow after noisy line problem fixed

Hi, wonder if you can help me?

 

My broadband connection has gone very slow over the last few days. At first I think it was because the line was noisy, and after an enginner came round and tested it, said it was coming from an extension cable, and that I should plug the router and phone directly into the main socket. I've done that, and the line is no longer noisy but the internet is still very slow (0.5mb whereas before it was in the 7-8 range).

 

After looking through the forum I see that this might be caused by me having reset the router loads of times in an attempt to fix it, so that I should just leave the router for 3 days or so and see if the line speed improves. Have I got this correct?

 

Here is a copy of my ADSL status:

Downstream572 Kbps
Upstream1,216 Kbps

Re: Broadband speed gone very slow after noisy line problem fixed

Your noise margin is very high and you are likely in a banded profile. You need to maintain 3+ days of stable connection and the banding should start to release with an increase in connection speed as noise margin drops. See this link for more on banding on ADSL2+ lines: http://www.plus.net/support/broadband/speed_guide/broadband_terminology.shtml#bandedProfiles

Re: Broadband speed gone very slow after noisy line problem fixed

Well after leaving the router overnight the connection reset by itself, and now the speed has gone down even more 😞 The noise margin has gone down a bit though. 

 

My hub is an old BT Hub 2, would buying a new Hub help in anyway? I fear I'm never going to get 3 days of continous connection.

 

 

Here's my stats now:

 

Line stateConnected
Connection time0 days, 2:53:11

Upstream1,236 Kbps

Re: Broadband speed gone very slow after noisy line problem fixed

It should not totally reset itself unless its faulty.

 

See

Reported problems with the Home Hub 2

 

Is it actually resetting, or is it just the line disconnecting?

 

The clue is normally in the event log, which will show ant disconnects or restarts.

Think it was just the line going down, this is the event log around the time:

Re: Broadband speed gone very slow after noisy line problem fixed

Then it looks like you have a problem with your line, or internal wiring.

 

Try connecting things up as shown below, and leave it for a few days to see if you still get the disconnects.

Also dial 17070 option 2, and see if you can hear any noise on the line.

Re: Broadband speed gone very slow after noisy line problem fixed

It's been in the test socket for the last couple of days, and I've done the line test and there isn't any noise (well there's a slight hum, but it's a cordless phone and have read that that is normal?). It's like it was before I had the noisy line problem, and the enginner who came over on Friday tested that socket and said it was fine.

Re: Broadband speed gone very slow after noisy line problem fixed

There could be a high resistance connection somewhere, but you would have to report it to the helpdesk and hope that an Openreach Field Technician can find the fault.

 

One thing you can try, is to ring your home phone number from a mobile and just let it ring for a couple of minutes before you answer it.

Its surprising what the 80V AC ringing current can do to fix a high resistance connection Smiley Wink

See if that stops the disconnects.

 

It could still be the HH2, but without another router that you can try, its going to be difficult to prove.
