It just illustrates that it's not a hardware issue with your mac it has to do with the interoperability of mac's and cisco routers that the large isp's use on their back end. Is telenet a highspeed(cable or dsl) provider? The key part was the self assigned ip address, go into network preferences, show network status and it will say it's a self assigned ip. What ip does your g3 have? Most likely it will be a non-169 ip that can be routed. You said you've never connected with the g4, do you know how many ip address you get from telenet? In my example comcast gives you one ip and you can lease a second if necessary, or get a router, which gives out internal ip's to the macs. Try shutting down your macs, unplugging your modem, wait thirty seconds, plug the modem back in and wait for the lights to come back on(cable, internet light). Bypass the hub and plug the ethernet cable from the mac into your modem, most likely you'll get a similar ip to the one the g3 had.
