I have 2 computers, one that is hooked up to my 2Wire router through CAT5 and one that is using a Lixus wireless card.  Both can get out to the internet.  The problem is that I can not get the two of them to communicate to each other.  I am trying to get Diablo to play over the network using IXP so that my son and I can play.  Can anyone please HELP!you could just connect the 2 computers together witha cross over Ethernet cable. Or re they both in the same workgroup? can you see the other pc in you network places ( click network places and then workgroup computers )I am sorry Lerninmore, you gave wrong directions (LE: although I tend to agree with your opinion regarding a cross over cable - perhaps he has some fragmenting problems in his actual configuration?). He has network CONNECTIVITY, he does not have to change cables, to check network workgroup etc. He just has to check if protocols are installed and no firewall is blocking their communication.

McHunt, is IPX protocol installed on both computers?
IPX is installed on both computers.  They are conected through the router, not a crossover cable. The computer that is conected to the router via the CAT5 can see the wireless computer but not the other way around. I have opened every port for gaming that I can find on the router as well a enabled file and printer sharing. I have check my firewalls and they seem open to intranetwork communications. I have run the HOME network wizard (probably a huge mistake) and both machines are on the same workgroup.Quote:

Question: you opened to wan access? (for outside access of your local area network, for computers not being connected to your router) Mistake. You should not. You must not. Do not!!!
File and printer sharing I assume you enabled on each computer and you did not changed router configuration for that.

Disable (for testing) the firewalls and try again to set up a game.Gaming ports, I'm not a total idiot.  I've tryed bridging the router and it worked  for the TCP/IP intranet, but I still can not get the IXP to work.  Have you disabled the firewalls for testing?yes, I've disabled the fire walls for testing, and have bridged the port for the cat-5 on the router but still can not get IPX to work. TCP/IP works GREAT, with or without the bridge. I am sure you searched the NET for MOR informations, so please don't be upset if I place here a link:

(see the last posts).
Also I saw that they require NetBIOS names (so you will have to enable NetBIOS over IPX/SPX). I don't understand why
