What does the connection between the PC and the DSL modem look like?
Ethernet, I hope. In that case, you can use a "sniffer" program to capture
a sample of actual traffic on the line. Do that when it's slow and it may
be possible to determine if
- some background process (perhaps spyware/adware/virus; perhaps Skype or
torrents or P2P...) is using up a lot of your bandwidth
- some remote system is trying to attack yours
- something else weird is going on
Ethereal is a freeware sniffer that can save captured traffic in a format
spoken by various analysis tools. If you can capture about 500KB to 1MB of
traffic, contact me directly and we can arrange for you to send it to me --
I have access to commercial tools which can analyze it.
