It sounds like you are using an AAUI (apple attachment unit interface) for you ethernet. Are you using a category 5 ethernet cable with rj45 connectors. You should not be able to stick an ethernet cable into a modem port, the rj45 is bigger than the jack a phone uses. If you are not getting a status light on your hub, something is wrong. That is called a layer 1 problem. So, check that you are using an ethernet cable. Perhaps switch the network cable the windows box is using with the one you are using on the mac. Does it still work on the windows box.
What kind of mac are you using? Oh yeah, do you have a network control panel under 7, i seem to remeber one that you used to pick which interface you want to use to connect to a network. Make sure that your ethernet port is showing up.
