I'm having some problems setting up a network with my 2 computers (see sig for specs), and I'm wondering if anyone can help me get it working... Both computers have network cards (obviously), and I'm trying to use a Linksys hub to connect them to each other, but more importantly, to my cable modem. The problem is this: when both computers are plugged in, no matter what ports (there are 8, but #8 is a shared uplink port, so either you plug in the modem into Uplink or something into 8, but both can't be filled, so I don't put anything in 8) I plug them into, the 1.5GHz machine ("upstairs") is the only one that can access the Internet. If I plug the 1GHz machine in by itself, it works fine, or if I plug it directly into the modem, it works fine. But, when plugged into the hub with the upstairs machine, it can't find a DHCP server to obtain an IP. I've tried setting up a network between the 2 computers when plugged into the hub using the Windows networking tools, but they can never see each other. Oh, and whenthey're both plugged into the hub, the downstairs computer shows up as connected on the little LED panel on the hub, and like I said, it works fine if plugged into the hub alone. So, anyone have any ideas?
Networking help, anyone?

Sounds like your modem is set to issue only 1 IP. RoadRunner has this feature, if you don't call and request multiple IP for the modem, only one can be issued by the modem. Perhaps, some DSL company could do the same.
If you are not using NETBUEI protocol and relies only of TCP/IP for your internal network, they won't see each other if the other machine has no IP. Try to put NETBUEI in both machines and see if you can see each other's computer.

Actually, according to the hub's manual, you're supposed to plug a cable modem into the Uplink port.
/me slides into the room! 
Does your ISP give you two public IP#s? Because that's what you're trying to get. If not, you need a router.
What is the TCP/IP setup for each computer? Is everything (gateway, DNS, IP, etc.) set to off or auto? Are they both in the same workgroups? Is file and printer sharing installed on both? Is something actually shared on both computers?
Before Poof shows up to yell at me, IMHO I would only bind F&P sharing to NetBEUI. It's slightly slower at first than TCP/IP, but it should be more secure.
Edit: BTW, get on ICQ!
As for the uplink port, it depends on how the cable modem is made. Some need the uplink port, some don't.

Ok, so what exactly is this NetBUEI thing? And I guess I'll have to look into this 2 IP thing, I think they do allow you to have 2, because I know several people who have 2 computers connected in this manner. By the way, I don't really care about having a network between the 2 or being able to share resources or anything, I just want them both to be able to access the Internet
NetBEUI is another protocol, like TCP/IP. But NetBEUI isn't routable, so it will only work on a LAN. You don't have to worry about people connecting to you through NetBEUI over the internet.
Actually, if you do keep two public IP#s, you'll have to use NetBEUI for F&P sharing. If you try to use TCP/IP, besides being really insecure, I think you'll be limited to the cap of the cable modem even for local sharing.

Like IsOs said, unless you've requested multiple IP's from your cable company, you will only be able to run one PC off the cable modem. In my area of the US, that runs about $10 per month more. Don't know what it would be in Canada.
An alternative to a hub would be a router that allows NAT. Another alternative would be proxy software which allows one system to act as a proxy for the other systems on your network. I'm not sure what's out there now, but I used to use GateKeeper from InfoPulse and it worked quite well.

Hmm.. since I don't have multiple people gaming at my place at any one time on the same server, 1 public IP is enough for me. I have a LinkSys Cable/Router hooked up and it comes with a built-in DHCP server - so I can have however many PCs routing thru the one public IP with no problems.
As others have pointed out though, you're going to need a router to accomplish what you want, or spend more money to get additional public IPs; if it were me, I'd go the router way. Unless you're needing to have the ability to have both PCs play together in the same LAN game on say.. the GameBox(is it up yet?), you probably won't need more than a single IP point.
In fact, my employer(library system) has just four public IPs for everything we do, and we've got about 600 network devices inside our organization.

Problem solved... My Internet account does come with 2 IPs, but you have to call them to activate the second one... Thanks for all the tips and such though guys

Depending on what O/S he is running, DM could have also set up ICS (Internet Connection Sharing) which provides DHCP support. Getting a router/switch or router/hub would be best, but if all he needs is Internet, then ICS will work fine. Again, depending on the O/S.
Mute point, since his cable provider gives him 2 IPs. Now if he wants to add a 3rd PC, he will need to do something else, either ICS or get a broadband router.
Since you already have a hub, you could get the Lynksis broadband router with just 1 LAN connection, and plug the router into the hub.

Nah, this will do for now... When we move into our new house in about 7-8 months time though, then there'll be a lot of computers to set up, but that's way in the future

Oh, and before I forget, another good way to setup a router is to get an inexpensive PC, throw a couple of NICs in it, and run the Linux based Freesco software. IT takes minimal system requirements (runs off floppy, 6meg RAM, etc..) supports up to 3 NICs and 2 modems.
One of these days I plan on giving it a try.

]Ray: If I were to have some kind of server, you can bet it wouldn't be inexpensive, it would probably be a dual Athlon XP (or MP) system... Overkill, absolutely, but it would be a great excuse to get some kickass hardware and really increase my SETI production

That's the kinda talk we love to hear! LOL!
