Ethernet connection

Excuse my ignorance, but, though I've been on Macs for years, working from home I've never had much to do with networking. I've just set a G4 up for my wife in an upstairs room and I've got an ethernet cable i had made up for my son when he was at college, so I could connect the 2 macs up. However my Mac is connected to the internet via ethernet. I'm sure I know the answer but is this when I need a router so I can connect both Macs and have them on the net?

Yes :)

I use a Netgear WGR614UK, it's great!

Thanks for clearing that up, asheep. My son rang this morning and a friend of his has just bought a wireless router and said he'd bring his old one round and fix it up for us. Damn nice of him.

Good timing! Have fun, any problems, most of us can help you out I'm sure :)
