not going to waste your time with filler story:
- brother wants Live at his house. so he bought a hub (everyone was sold out of routers) and I attempt to hook it up.
- it is a 5-port Linksys hub.
-Yes, I know a router is better, I have a router for my stuff at my place.
-port 5 is "uplink" and I plugged the cable modem into that
- power cycled everything with Xbox 360 in port 3 and PC in port 1
- the 360 passes all the tests, finds the gateway and everything and gets online (it needs to re-do this, however, every time the hub is powercycled)
- the PC, however, cannot. It complains about no DHCP server to get to, and never finds the gateway. All it can ever find is the "automatic configuration address". Even looking at the IP addresses in the 360 and copying them over doesn't help. Changing the port does not help
- ipconfig /release works just fine, ipconfig /renew complains about no DHCP server
- the hub apparently has no browser interface
tl;dr:
Brother bought a hub, the 360 can get on the internet just fine, a Windows XP SP2 computer cannot. Is there anything I can possibly besides having him get a router? (which I will, but if it's just human error, the hub will be just fine)
also, the PC can get online just fine directly plugged into the modem, and worked fine with a Linksys router before this.

Simply put, without a router, you're relying on the services of your network provider. Oftentimes, at the residential level, you'll only get one slot. Once that first request is made, their network will refuse to make any more.
I remember now. Routers can act as switches and hubs, but hubs can't act as switches and routers.
Dear god I wish they would just make it all routers.
That wouldn't work all that well either.
Switch: Transfers packets using destination MAC address pulled from the packet.
Hub: Input on one port is echoed out all other ports.
Of these, a home Router with integrated switch, such as the WRT54G, is the best solution, and many times the only solution for hooking up two or more devices to the internet. It is the only solution that provides any sort of protection for you devices from unsolicited incoming internet traffic.
To shop you'll be a going, you can't hub over an ISP's network unless they've specifically setup something on their side that says you can.
