I am attempting to network 2 Win XP Pro boxes connected through a hub which connects to a surfboard motorola modem. I can access the internet from both computers. I have the same workgroup names, have all the things correct, and I can *sometimes* map the network drives and share printers, but after about 10 minutes it says it can no longer locate the other system on the network. I have both drives and folders shared on each computer also. A friend of mine said it might be caused by the hub and possible collisions of information and recommended getting a switch. Would anyone else recommend this or have any other possible solutions or things i can try to fix this problem. Thanks alot.
