Information needed to diagnose speed issues on a Broadband Connection -
1) Log in to the router, look for ADSL or Broadband Status. Look for download and upload speeds. 8mbps = 8192kbps, 2mbs=2048kbps. If your on 2 meg connection then you should get upto 2048kbps. If this looks ok your BBI Line is fine, next check your PC. 2) Start Run type CMD 3) Type Ping 127.0.0.1 results should say <1ms if more than 2ms, then there is a PC issue. In this case run Netstat -a are the a lot of Established connections? Do you use P2P software, if yes then you will need to check your pc for spy/ad ware or viruses. 4)If pinging 127.0.0.1 was ok, then Ping your routers IP address, times maybe upto 3-4ms, any more then the issue is with a wired/wireless connx. 5)If that is ok and not above 4ms, then run a trace to a web address. BBC is best. So in CMD type Tracert BBC.co.uk look for times above 50ms, or a lot of asterisks. Make a note of the line number and address. The pattern for this is lines 1-3 are local, 3-8 network, onwards will be the web you are tracing.
The BB line speed is ok, I would check with this ISP about the Line Attenuation and Noise Margin. Try the tests I suggested earlier if you call the ISP they will prob run these tests with you. (I used to work for another ISP tech support)
