And if you've only got a modem (as opposed to a Router) than you're going to be needing a hub.
as far as i was aware there waas no need for router OR a hub.

i beleive that it should be possible to simply connect the two ethernet cards via a crossover cable

Actually he does.

One problem with Microsoft is that they keep calling things a different name than everyone else.

If you only have one modem, then you only have one IP address that can connect to the internet. As you can't have two machines on a network with the same ip address and netmask, you need a router to take requests from your machines, send that data out on the internet using the IP address your ISP gave you and then route replies back to the originating machines.

Now, microsoft may hide all that underneath piles of kiddy speak, but that is what you need. The router can be one of the machines on your network or a hardware router. You do not need a hub as you can connect machines serially with a terminated coaxial cable.

In my view, by far the best solution for the original poster is to get himself a router (perhaps a wireless one as these are always useful), plug it into his modem, plug his machines into it, get himself a coffee and feel pretty good about himself.

think im gonna reprep the whole lot and start again tmrw (ok maybe wednesday lol) and see how things go.

Hell, I got my WiFi ADSL router for free with my ADSL contract, I don't know what they cost.
They can't be that expensive, especially if you just get a 4 port router without wireless.

Why bugger around with crossover UTP? I've never been able to get one working, which is why I've always had a hub / router in between.

i understand that getting a router is easier (as well as more costly) but i do believe that it is possible to do in this manner. it is after all how i connect my ps2 to the net:

PS2 - crossover cable - WinXP machine - ADSL modem - internet

no hub, no router, no problems at all

However, I forgot to mention that before he gets his coffee he'll have to make sure that the default gateway on all his machines points to the router AND that host name resolution is set to the ISP's DNS servers on all machines too.

If that starts to sound a bit nasty then he can make sure the router can behave as a DHCP server and set up all machines on the network to use DHCP and point to the router. That way it all becomes automatic.

These wireless routers and incredibly cheap these days.

but not as cheap as my free crossover cable though huh πŸ˜‰

i have contemplated spending out for a decent wireless router but being a Scotsman im pretty mean when it somes to spending cash πŸ˜€

if it was impossible to do this using a crossover cable then i would give up and get a router but i know that it is possible to do (and im a stubborn bampot too which doesnt help).

i can see at least one other reply from someone who has managed this so ill redo all the connections ect tonight and see if i can get anywhere.

cheers all.

free solution: connect one computer to your modem, then connect your other computer to the first one. install and set up LANSuite (see my link on the previous page) on the first computer. once it's set up, then you're ready to go online! it's not the best solution, but it works and it's free. i'm a scots studnet (like a typical scotsman, but even more tight with money) and my flat last year was done this way (although we had a hub after the router thingy so it was easier to connect all our computers. the hub eventually broke, but that is kinda beside the point). cost all of £10 for the cables.

Well the best of luck to you πŸ™‚

Perhaps it will help in your googling if you are aware that what your are creating is an ip network using a crossover cable. Also, you are setting up one machine as a network router and probably a DHCP server. Your second machine is going to be using DHCP to get it's ip address and netmask from the first machine. It will need to get name resolution from your ISP's DNS servers and it will have it's default gateway as your first machine.

I can't help with the specifics as I don't have much experience with Windows.

I use an ADSL modem into this laptop upstairs connected to the desktop downstairs with a crossover cable - both are on XP which is the only difference to your set up.
I occasionally [say monthly or so] have to reset it all for mysterious reasons, but all I do is run the home/small office network set up wizard.
Just make sure you do it first on the host computer and then again on the other.
I can assure you it is certainly possible without a router or hub.

Sorry to bang on about this but it isn't. You don't need a hub but you DO need a router. I would guess that when you select the "home/small" office network wizard, it configures one machine as a router. It just isn't possible to have multiple ip addresses going through your modem without routing.

I only keep making this point in case it helps someone who doesn't have the benefit of a "wizard"

ok, let me put that another way.
You do not need a separate hardware router. With ICS the host computer connects to the internet and the other goes through the host.

Doesn't seem too pedantic to me to point out that you must have a router. If you like, I'll add that routing on its own is not good enough and you actually need ip forwarding but I didn't want to go down that road.

From one pedant to another, you just have.
