Can download speed be improved?

[tigwa]

Hi,

Can anyone give any ideas on how to improve download speed with the following stats?

Been on connect package for a week and was told line could take 8mp.
I'm 93m away from exchange, have tried connecting with test socket and increasing/decreasing RWIN with TCP optimizer all with no real improvement (download speed never above 2000kbps).
connected via the ethernet not wireless


Last Result:
Download Speed: 1959 kbps (244.9 KB/sec transfer rate)
Upload Speed: 386 kbps (48.3 KB/sec transfer rate)

Thanks in advance for any help you can give.

Where are you downloading from?

See what you get from here:

Namesco BroadbandMax ADSL Broadband Bandwidth speedtest | Test your ADSL Broadband connection speed

*Edit* Also there is a 10 day training period on connect where your speeds may vary, but looking at your stats I can't see how that would make much difference.

You seem to have excellent stats, I dont understand what could be causing the problem apart from a dodgey speed test

[tigwa]

Thanks for the replies

Lazarus - That is the site I'm using for the speedtest.

Also note i'm on the exchange just up the road from you STFAWLY! Whats the sky service like in Hythe as have family and friends considering the switch to sky?

Looks like i'm going to have to give sky a ring and see if they have any suggestions

[Lazarus]

Your connection speed is always reliant on the distance from the exchange. I'm lucky, pretty close to the exchange (530m acf). Saying that I've always had an excellent connection and not lost it once in 2 months now. I also happen to know a couple of engineers (sky and Bt) which can help.

Called sky and was put through to tier 2.

Had a look at netstat and had 20 connections plus so he said difference between download speed and connetion speed is due to spyware etc!

Just done full system av scan (nothing found) and installed and run spybot. re-ran netstat this has improved slightly but still have a number of localhost connections and speed test not affected?!

Could anyone tell me if
a) this is likely to be affecting download speed
b) what are the localhost entries all about?
c) is it worth going back to tier 2 to investigate further? afterall i'm only paying £5/month! and this is my only issue with the service at present?

Thanks again

Download process explorer
http://www.microsoft.com/technet/sys...sexplorer.mspx

find the processes opening sockets and check who they are and delete these as necessary.

Alternative, do a netstat -a and on task manager,process tab,then select view, select PID column, the PID in task manager will correspont with the netstat -a ouput PID, determine which program is running and opening the suspect ports.

Still having no joy with improving my speed. Have spoken with Sky again only to be told if my router stats are showing 8128 then I'm downloading at 8mbs and the speed tests / download programes are incorrect!

Well, I've spent some more time reading various posts on the forum and have now done the test at Test Result results are as follows:

Test1 comprises of Best Effort Test: -provides background information.
IP profile for your line is - 2000 kbps
DSL connection rate: 448 kbps(UP-STREAM) 8128 kbps(DOWN-STREAM)
Actual IP throughput achieved during the test was - 1825 kbps

Am I correct in thinking that the reason why my speedtests never go above 2000kbps is due to the IP profile being set to low?

Is there anything I can do to rectify this? if not is it something sky are likely to do something about or am i going to get fobbed off with more of the same?

thanks.

I believe that Sky could get your IP profile changed, although I'm not entirely sure if they could do it themselves (I suspect Tier 3 may be able to do it) or whether they have to ask BT to do it for them.

One thing that someone else has said worked for them, was to plug in another router. You shouldn't need the password and username because the router just has to synch with the exchange. This should force a resynch, hopefully at a higher rate for the new router. Once it has synched successfully with the exchange (leave it for an hour to be sure), plug the sky router back in. Because the router and the exchange now have different synch rates, it should force them to resynch again at the higher rate.

Haven't tried it myself but it seems to makes sense.
