I rewrapped that. In future, please hit return.

I'd start with using both machines to do pings. First step would
be ping round trip times to the router. Then ping times to the DSL
modem. Then ping times to your proxies (if any). Then ping times to
your DNS and alternate DNS.

Don't do many pings, just a few when going outside your own equipment.
Be polite. You can learn as much from twenty pings as from 20,000 pings.

Even 10 Base T or 2 can outrun DSL easily, so I'm presuming it
doesn't matter whether your router and your ether NIC are negotiating
10Mbps or 100Mbps. But this may not be true. If your ether NICs have
the ability to indicate negotiated speed, find out. There may be LEDs
on them indicating speed.

This presumes, BTW, that your topology is like this

[PSTN]<--ADSL-->[MODEM]<--EtherNet-->[ROUTER]<---+---->[WINxx]
                                                   \--->[Linux]

If that diagram isn't clear, then the point is that the
Linux machine is not "behind" the WINxx machine, which is
acting as a NAT or router itself, but has a direct connect to
the router.

You have found the bank of Larn.
I can explain it for you, but I can't understand it for you.
I speak only for myself, and I am unanimous in that!
