WinXP Internet Trouble (Cable Modem, Hub, NIC)

[Hellblast]

Hi all
My roommate has problems with his XP machine. Here goes:

Cable-Modem to NIC works fine

Cable-Modem to Hub to NIC hardly works at all

Checking the Network statistics reveals that all works fine with the direct connection to the cable-modem, but when the hub is in between the NIC and the cable-modem, zero packets are received.
Occasionally, a handful of packets makes it through, but then that's it for a while. Internet doesn't work then at all. Can't get the DHCP information and all that.

What would keep the computer from receiving packets if the only difference is the fact that there's a hub in between?

I tried another hub, no-go. Messed with all the darn wizards, no-go. Switched cables, no-go.

HELP! Please. . .

Most Internet Cable services Authenticate via the MAC number of the NIC in your computer. When you put the hub directly to the Cable Modem they get the MAC number of the hub, and disconnect.

Want to know more, read the content of the following links:

Basic Options for Internet Connection Sharing

Hubs, routers, switches, DSL, LANs, WANs...?

Problem with that theory is, that it worked fine before! He had a Win98 computer and the network worked fine, then came with XP and it worked fine for a week or two, then it stopped working right (see above).

I'm still looking for a setting, cause it can only be WinXP doing something weird we can't see.
