I agree to your analysis that "The NIC and Router do not properly
auto-negotiate".
As to the cable, I have done a set of test (see my reply to John Jones) and
can't see a problem unless the laptop'sNIC and the Router need a very
special one.
The only setting of "Link Speed & Duplex" that make the green lights flash
at both ends is "100Mbps/Half Duplex" or "100Mbps/Full Duplex", which
indicates a very unstable connection.
Any idea on how to make the two compatible/auto-negotiate?
