Ok. You mean the Quad, then?

They all go into a Netgear 8 port gigabit router and then connect
to the internet through a Netgear modem.
Please clarify - exactly what model router? what model modem? This
is to some sort of cable service or DSL or ?
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?
Inaccurately. By downloading a 5MB file from the same server and
noting the data transfer rate in the download window.
Inaccurately is an understatement. To many unknown variables -
server speed, the throughput of the network between you and it,
browser overhead, browser averaging, etc.
Use a real speed test, please. Of course, please make it clean test
- no other apps running and no other network traffic on your LAN.

>Please clarify your units. Do you mean megabytes per second or megabits?
Sorry, I mixed units! The G5 bottom port - 400kbps, G5 top port -
20-30kbps, all other machines 20-30kbps (kilobits per second)
And your internet service is supposed to be 8 Mbps?
(7.9 MB/sec would be ~80 Mbps -- expensive).
30 Kbps (less than V.90 dial-up speed!) over an 8 Mbps service is
pitiful. Because that affects all your Macs, it's starting to sound
like you have a cabling or switch or router or modem issue. The
information from the ifconfig (Bruce's reply) will be helpful.
>Check to see what speed your ethernet link has sync'd at.
Not done that yet but my Macbook connects with other ethernet networks at
full 1000mbps yet when using the same cable and router port as the G5
bottom ethernet port, the speed changes.
Anything talking to that router via wi-fi? (You didn't say exactly
what model router it is, so I'm guessing it does wi-fi). Asking
because I've seen many less-expensive routers taken to their knees
because of being overloaded.
