Hi All, What's agood way to test the ethernet port on my G5 Power Mac SP 1.8G? I have other Macs on the network. My wife complains that the internet is slow & can't stream video. Th is computer is wired to a gigbit switch, then to 100 Mbit switch then to the router. I have a 24" iMac connected to same gigibit switch and have no problem with the internet speed. When I try to send a large file between my iMac & the G5, the transfer is slow. I checked in System Profiler and both computers detect the ethernet speed as 1000 Mbit (1gigabit or something like that). Ideas on how to resolve? Gigbit ethernet cards that will work in the G5? I don't have Airport on the G5.
