Ok i hawe 2 Comps, and only 1 net, my modem has two Connection types (TCP+USB) I want to connect them, because i cant share the net With my sister My Nb has Windows Vista, ANd her PC has XP ,
What besides router, do i need to do???

Firstly, I'm afraid you cannot simply connect your modem to both machine - it just won't work. The modem has two connections depending on whether you want to connect it to a single machine (USB connection) or to a router/switch to service a whole network of machine (Cat5 Cable).

If you want to allow both machine access to the Internet, there are a few ways you can do it. However, by far and away the easiest method is to simply purchase a router with a built in modem (ADSL/Cable depending on your connection, assuming this is broadband). Using this, you can either plug each PC into the device using a network cable or connect wirelessly if you have purchased a wireless router and both machine have wireless network cards. From here, you will be able to log on to the router using the instructions supplied in the manual and configure the network and modem. If you use DHCP, you should in theory then be able to simply plug your phone line into the modem and both machines will have access to the Internet.

Alternatively you can create a peer to peer network and use one machine as a gateway to the Internet - this is much more fiddly, slower and requires the gateway machine to be on if the other person wants to access the network.

It is also possible to purchase a dedicated router or switch and connect your existing modem to it using a network cable. Using the same procedure above you should then be able to set up a LAN and connect to the internet.

I haven't gone into detail because I do not know:

- Your Internet connection type
- Whether your PC's have wireless cards or not
- What equipment you are prepared to purchase (modem and router or a standalone router)
- If you currently have a network set up

If you can go into a little more detail I may be able to give you customised instructions for getting your LAN up and running and supplying both machines with an Internet connection.

Love the picture, by the way (+1 for that!)

quick question, the switcher in the picture, is that a phone line filter or a switch for computers?
If it is a filter it needs to be on only the line to a phone, and will interupt your internet.
If it is a switch you should have the hardware in the other order:
2 comps -> switch -> modem -> unblocked phone line.

If you can connect 2 computers by ethernet cables to the modem you modem likely has a small router built in and a switch would not be necessary, unless it adds wireless.

Also the OS is not important when connecting the computers, each computer will individually handle the connection to the modem, router, switch, or what have you if it is setup correctly.

well, i have the Internet line to switcher, that when i surf line wouldnt be (idunno the word umm... say diconnected ) so i can surf the net with a phone u got the picture (i drawed the picture with microsoft paint)

ok i can show you why i need a swicher (actualy to make it simple, i need for the phone)
I curently done like this :

And i need to ask can i make them work by doing this???

The art of MS Paint drawing is a dying bread but it is much fun

ok, if the setup up to the modem works for 1 computer then the 2nd scenario is definatly possible. Simply check your modem if it has 2 ports like the one your XP computer is currently plugged into, then simply plug the other computer into the other jack. If not, you will need either a router or a switch. For only 2 computers it is probably more efficient to go with a router as it will also allow you to create a network more easily if you wish (technicalities on how switches work... they can be slower).

The only change that is made is the cable from your xp comp and the other comp plug into the router. There will be a port labelled in or wan or something to indicate the input of internet and plug a short ethernet cable (router will likely come with one) from this port to the port your xp computer was plugged into.
Now your modem sends internet to the router which will then distribute it to the 2 computers connected to it.

The back of my modem looks like that
And front looks like

the internet cable would plug into the router, and the router will have 4 or more numbered ports to plug your computers into.

Yes, you will need to purchase a router in order to share the connection. Strictly speaking there are other ways of doing it, but if you can afford a router it will be much quicker and easier to set up.

To echo William Wilson, you will need to purchase a router in which you will be able to either plug both machines into or connect wirelessly depending on whether or not you have wireless network cards in both. From there, you will need a short network cable to go from the router (there is usually a separately marked port) into your modem's "Internet" port.

Assuming your new router supports DHCP, you shouldn't need to do anything other than connect everything and perhaps enable DHCP support via the networking TCP/IP properties on both machines.
