Are you experiencing slow speeds?

Check the following :

Line is direct to master socket, straight through with DSL cable to filter
Running through any extension cable can cause the quality of the DSL signal to drop. Remember the difference between getting an 8Mb service and a 4Mb service is 200 metres, so a cheap extension cable from the market can effect the speed.

Using USB some peripherals connected to USB such as printers/scanners/etc could effect bandwidth so its worth removing these too
Other equipment using the computers external bus may be the cause of slowness

Have no fax connected
A fax on the line can interfere with the DSL signal, even if its filtered.

Run a full system scan for viruses?
A Trojan virus on your computer will run in the background scanning for other computers to infect, this will cause a major drain on bandwidth

Have no programs running in the background, check task manager - make sure all programs are closed
Most current software keeps itseslf up-to-date by downloading updates, this of course includes Windows itself which can be downloading updates in the background that run into 100's Megabytes

Does you experience packet loss when pinging router?
If you are experiencing packet loss when pinging your router the fault is more likely to be internal rather than the line.

Is it a Macintosh OSX ?
Is so, you need to download this update from Apple: http://www.apple.com/support/downloads/broadbandtuner10.html




Netstat
Netstat displays a list of the active TCP connections the computer is managing. The local address will be the computers 192.168.0.x IP address, with the foreign address being the IP address they are connecting to. The foreign address also lists the port or protocol it is communicating on.


If all the above has been checked please run the command 'netstat' in the command prompt.
Win 9x, ME: Start, Run, type in 'Command' click OK
Win NT, 2K, XP: Start, Run, type in 'cmd' click OK
This will list all open connections running on this machine. If the list is long then the problem is likely to be Trojan virus related and you should do a scan for viruses and spyware.

The more open connections the more bandwidth will be taken up slowing the connection.
