I recently bought a PowerMac G5 Dual 2.3GHz (late 2005). It is
running OS 10.4.11.
It is connected directly to DSL modem via Ethernet cable.
When I start up the computer or wake it from sleep, I cannot connect
to the Internet. The Ethernet connection is not recognized in the
Network Status window of the Network preference pane in the System
Preferences. The Ethernet light on the modem is off. (The Internet
light is on.)
However, if I unplug the Ethernet cable from the computer and then
plug it back in, all is well. Network Status shows "Built-In
Ethernet 1 is currently active and has the IP address..."
But if I put the machine to sleep or am even inactive for a while,
the Ethernet connection "disappears" again.
The problem occurs with both Ethernet ports, and when I created a
New Location.
I'm a bit confused - does your Powermac G5 actually have two ethernet
ports? To the best of my knowledge they normally only shipped with
one. Unless, of course, you've added a port.
Also, unplugging and re-plugging the Ethernet cable at the modem end
does not work; only re-plugging at the computer port.
Any and all suggestions appreciated. Thanks.

It might be helpful if you provided a bit more info about your DSL
connection and G5. Does it actually have two physical ports? What
brand and model is your DSL modem? Does your DSL connection use PPPoE
or DHCP?
How long do you have to be "inactive" before the connection drops?
Does your monitor go dark in that time? When you say inactive, do you
mean you stop using the G5 or stop using the Internet?
You should also check the system log for any errors. Offhand, I'd say
that for one reason or another your G5 is having problems waking the
Ethernet port after sleep. Have you tried disabling sleep entirely to
see if the problem goes away? It's a long shot, but you might also
want to try a new Ethernet cable.
