This G5?

They all go into a Netgear 8 port gigabit router and then connect to
the internet through a Netgear modem. The download speeds form the
internet to all the machines except the G5 fluctuate between 20 and
30 KB/s. The G5 achieves download speeds of around 400 KB/s with the
cable in the bottom of the 2 Ethernet ports.
If I plug my Macbook into the network using the cable from the G5 I
get between 20 - 30 KB/s.
If I plug that same cable into the top port in the G5, the download
speed drops to 20 - 30 KB/s.
The modem is, allegedly, connect to the internet with a downstream
speed of 7.9MB/s.
How exactly are you measuring this speed?
Please clarify your units. Do you mean megabytes per second or megabits?
Two ethernet ports on the G5? One is built-in and the other is
something you added?
I've tried swapping ports, cables etc and it always seems to show
that the bottom port on the G5 is getting hugely better download
speeds.
Check to see what speed your ethernet link has sync'd at. Some
switches have idiot lights that say. Otherwise, you'll need to check
your system.log for a line such as (below). In Console.app, when
viewing system.log, if you search on "enet" or unplug then plug in
your ether cable, you should find the line.
