Network Problem
In normal operation, the network is invisible to the user.
When a system seems slower or has difficulty accessing
data, the network is most likely the problem. Consider the
load on the network as a possible cause besides hardware
failure.
If a system's network cable could be easily kicked by a
user, then it might have an intermittent connection at the
system or wall receptacle.
Checking a component means checking the electrical con-
nections and fit.
N
Swap patch cable ports at
the first router/node.
Did this solve
