Are they *sometimes* on the same subnet? That would explain the good transfer speeds you *sometimes* get. > the speeds seem to change at random and sometimes i get an ip conflict > message popup in windows. > > it seems that my problem is that sometimes the data goes this way: > linux box > hub > big, bad internet > hub > windows box > > and sometimes my data goes this way: > linux box > hub > windows box > > how do i make sure that the latter is the only thing that happens? Use NAT. i.e. Take control of your network. Using one of your machines as a router for the other(s) will improve the performance of your local networking, as well as the inter-networking of your neighbors (and this is why I wish cable providers would recommend or sell routers to homes with multiple PC's). If your "local" networking is traveling out your cable modem, you have two problems: All your traffic may be sniffed by your neighbors or provider Your local network traffic is slowing down your cable modem network for everyone. I suggest that you reorder your network so that your cable modem connects directly to your Linux PC, and (you'll need a second NIC in the Linux PC) the Linux machine also connects to the hub which the Windows machine is plugged in to. Your Linux box will provide an effective firewall for the Windows machine. As an added bonus, if you only have the windows machine on the inside, you can connect it to the Linux box with a crossover cable and get full-duplex networking (which you would otherwise need a switch to do).
