Complete Idiot's Guide to PC to XBOX Networking.
First determine your network architecture. Really for your home network, there's only 2 main types. One in which all the devices connect through a switch/router/hub, and a direct connection from XBOX to PC.
If you're going from the XBOX to a switch/hub/router, then the cable you need is a regular ethernet cable. straight through, however you want to put it.
If you're going from the XBOX directly to a PC, then you need a cable that's meant to allow 2 Computers to talk to eachother, this is commonly refferred to as a Crossed or Crossover cable, M$ calls it a "system link" cable.
If the word "patch" comes up, ignore it. it's a nothing word. it's redundant. It doesn't necessarily mean it's crossed or straight.
Next your PC and XBOX need IP addresses that can "see" eachother. If you're hooked up to a router, just everything to "automatically assign an IP" or "DHCP" or the like. This is the typical setting if you have a router, or are using ICS. I could go into more detail, but I'm guessing you're going to need instructions for the "other" route.
On to STATIC IP addresses. This means, YOU are going to assign the IP addresses yourself, and not let any device configure them!
Ok, here goes:
I believe the flashbios defaults to a static IP address of 192.168.0.99
Sooooooo Next you need to go into the network configuration of the PC. I'm going to assume you're running Windows XP.
Start -> Settings -> Network Connections
(if it's not there, go to the control panel and pic network connections there)
In Network connections, right click the Local Area Connection, or whatever name it might be, and pick Properties.
From there dbl-click on "Internet Protocol (TCP/IP)"
Next click on the dot beside Use the following IP address.
Then enter the following info:
IP Address: 192.168.0.100
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.0.1 (doesn't actually matter, for this purpose.)
DNS Servers don't need to be specified either, but if you really want to put numbers in them, just put 192.168.0.100 and 192.168.0.99
OK all the way out, and they should be able to talk to each other now.
Open a Web browser, and go to
http://192.168.0.99/
The rest SHOULD be obvious.
PS: if the computer Normally is used for internet. Make a note of what the settings were before you change them and change them back afterwards or you'll likely be screwed for access. Probably "Obtain an IP address automatically".
Hope this helps. Lemme know.
(yes I copied and pasted this from a previous post of mine. Maybe I should do a whole guide/walkthrough and get a stickie!)
