Try testing speed at this link using a few nearby test servers and post your results:

Dear Togers,

Thank you for that. I have since uninstalled a few programmes including ITunes, just to see. I have also uninstalled Firefox, IE7 showed the best test yet, you will find it below; any help would be much appreciated. I have a 1 metre cable between the PC and the ADSL modem, and know that I am 275metres from the main connection box.

Incidentally my best test was with Oslo, not the country I reside in.

Thanks again for your support,

Best Regards,

Nico

Do this NDT to see if your network adapter card is functioning:

http://nitro.ucsc.edu/

The report is under the 'Statistics' button.

Dear Togers,

Never heard of that before, look at the results! -Where is the 'other network traffic' coming from?

Dear Togers,

If you do not have any background program running during the test (eg. files updating, or p2p), the likely cause would be some spyware/malware.

Goggle and scan comp with SpyBot and Ad-Aware 2007.

Some firewall and antivirus are know to cause speed slowdown - McAfee, Norton and ZoneAlarm.

If you do not use a router, you need a software firewall.

I use Comodo as firewall and NOD32 for antivirus.

Thanks, Togers...

I have comodo and am downloading NOD32, it has a license any way I can get a free version? - I will try it and let you know.. :-)

Thanks again,

A free antivirus would be Active Virus Shield or AVS. You can also try looking in the Security section of our forum for other recommendations.

Dear Togers,

Does that mean, that you suspect that there is a security flaw that is sucking up the bandwidth? And have we tried everything possible?

Thank you for your response,

The remark of NDT report:

Information: Other network traffic is congesting the link

means that it detected signals during the test that is not between your comp and the test server and that these signals are occupying part of the bandwidth. The test does not indicate where these signals come from. It could just be some background program running (eg. messenger, antivirus check for update or p2p if it is running, etc). It could also be some spyware/malware.

I usually scan my comp when my NDT report shows this remarks. I use SpyBot, Ad-Aware 2007 and a-Squared Free.
