[Klug-general] network lags - electrical interference?

[Andrew Spode Miller]

During those slowdowns, is it that you can't access the server, or that you
can't access any other machines on the network? That distinction is
important in diagnosis.

Rather than wiring - my inclination would be a faulty switch somewhere,
perhaps overheating and dropping down to hub mode?
