I dont know whats happened but in the last few hours my speed has dropped dramatically. I have try disconnecting and rebooting the router but it makes no difference. This is the BT speed test result (by ethernet not wireless) I normally get 50 down and 9 up

Hey,
What gateway are you on?  http://usertools.plus.net/@gateway/

[#3]

Which gateway
You are currently connected to the gateway known as ptw-ag04.
This is located in Telehouse West.

[#4]

Can you do http://www.plus.net/support/broadband/bbfaults/bt_speed_tester.shtml and make sure you get the results on the "Further Diagnostics" page if you get the option.

[#5]

Hi things seem to have improved (I havent rebooted or disconnected)
The test gives 45.57 Download and 8.25 upload.
When I click on further diagnosics it says this after running the tests.
You appear to have not logged on as speedtest@speedtest_domain. In order to run the next test you should login as speedtest@speedtest_domain.
Please wait while you are redirected..


I thinks thats because I cant do a further diagnostics test within an hour of a previous one ?

It should have allowed you to run the test. Oh well, not to worry.
As things improved later in the evening there's a good chance your problem was caused by what's being discussed in the thread over here.

The problem seems to be back again and I have tried disconnecting and reconnecting and have been on the following gateways this evening ptw-ag04,  pcl-ag02, pcl-ag04 and now ptn-ag03. It makes no difference to my speed. Speed tests are all over the place.
I am also running a Sam knows whitebox on my line if thats any help.

Can / will this issue ever be fixed ? Its obviously something you are aware of. I havent checked my speed for a few weeks as I thought I was getting a steady 50 Mbps. I feel like I am checking it all the time now

Thanks for getting back to us, glad to see things have improved somewhat so keep us posted.

[#13]

DuncanM:  It could be a peak time issue, rather than a particular gateway.  This doesn't match the problem we've been seeing wiht big spikes of latency.  Can you let us know if your speed drops tonight at peak?
Also, are you seeing any affects apart from the speed drop? I.e. lots of buffering on streaming, breaking up of VoIP, gaming lag etc.
Thanks.

OK, this speed test was about 5 minutes ago. Looks all normal. The only visible effects I see are buffering on You Tube and programs taking longer to download on to the sky box. A 2.6GB hour long HD program on BBCi Player normally will normally take 27 minutes to download to 100% on the Sky box connected via Ethernet when my connection is as it is below. Ill do another test in an hour of so. I dont use my connection for gaming or VOIP I'm afraid so cant comment on that aspect.

So, you are seeing buffering on Youtube right now?  Are you on HD quality?
