I've got a cable modem going into a 5 port 10 Base-T Xsense hub. Connected to the hub is a G4 desktop and a G3 powerbook. Currently, I can not get the two computers to share this connection. My G4 accesses the internet just fine, while the powerbook sits with no connection....and vice versa. Only one mac at a time can access the internet (after a restart). Is this because of the hub not being a 10/100 base-T? Any suggestions would be greatly appreciated.
