what do i need to have to use 2 computers simultaneously on one Internet connection?

If you have a broadband connection, the modem (cable or DSL) probably is a router as well. Even if it has only one jack, if it is a router, all you need then is a hub. Connect both computers to the hub and configure the Internet connection.

The most conventional way now would be to buy a router, all necessary connecting cables or wireless adapter cards if needed to connect two or more computers together.  However, this is a very broad question and is not specific enough to go into detail.    Information is needed on the reason you want to network, what types & how many computers, what operating system they use, etc.

You need to have ethernet card on both the pcs and get the same connected through cat5 or cat 6 with cross over cable. or you can have both connected through serial cable.

If you connect both of them with a normal cable to a hub they are physically connected.\n\nCheck the settings on both computers and either set both of them to a fixed IP address in any of the RFC1918 address ranges (192.169.x.x, 172.16.x.x, or 10.x.x.x) or set both of them to DHP and in the absense of DHCP they will randomly pick a IP address (you'll need to go and find it in ordeer to use it on the other machine)\n\nIf you can "ping" the other machine's IP address, your done (check that (personal) firewalls aren't blocking you).\n\nAs far as application, you didn't specify what you want to achieve, but typically you'll need to activate a server service on one machine and have a client on the other machine.

both system must have a network card (nic)\nu need a cross over network cable\nboth system must have same workgroup name\nthen share the folders\nif u want to access the internet- u need to install Internet Connection Sharing (ICS).\ndun forget your firewall - u need to allow access or the firewall will not allow u to access from the other system\nu can go to www.practicallynetworked.com to read all the tutorials on networking.

If I were you I would buy a router and then connect an ethernet cable from the router to your second computer. If your computer is far from the other then get a wireless router, then buy a wireless usb adapter for your second computer.

Install an additional network card on the PC with the BroadBand Connection (or check to see if it already has two NIC ports). \n\nMake sure the other PC has a network port.\n\nIf you don't have a hub, router, wireless modem or anything else listed by the other answers, simply take a regular network cable and cut it in the middle. \n\nNow connect the Transmit Positive (T+) wire from one end to the Receive Negative (R-) wire on the other end. \n\nConnect one sides' T- to the other sides' R+\nConnect the remaining R+ to the other sides' T-\nConnect the remaining R- to the other sides' T+\n\n(I can't remember right off hand which wire does what, so research the web or email me [cjmclellen@yahoo.com])\n\nTape the cable up and plug it into the two computers which will share the BroadBand connection.\n\nOn the PC that has BroadBand already, go to the Control Panel and run the Network Setup Wizard. Follow the instructions to enable a shared internet connection. \n\nDo the same on the other PC but choose the option "connect to the internet through another computer". \n\nBasically, your internet service provider thinks that only one PC is using the connection. And they're right in a sense. Only one PC has a direct connection to web. This same PC also has ANOTHER network connection, the one that links your two PC's together. By enabling ICS (Internet Connection Sharing) on the host PC, you have created a bridge between the two networks and it is serving as a Gateway. Though the second PC is able to connect to the web, it's IP address is local and is obtained from the host ICS computer. \n\nAnother method is logging on to eBay and buying a wireless broadband router and a couple WLAN cards or WLAN USB sticks. This way you might be able to pick up on your neighbors Wireless broadband connection and connect to it. Then, cancel your service and split your neighbor's bill with them. Or; if you don't like them, and/or you're a cheap scandelous bastard, just steal it and don't ever say a word about it.

Both support TCP/IP which you are using now. Set up each computer with an address on the same subnet.

use a router.  Plug the cable modem into the back of the router where it says "Internet" and each individual computer where it has ports for the CPUs.

Yes it is possible.  If you are using a windows network, the   configuration is almost identical to that of having 2 wired computers. \n\n1. Configure all computers on the network to have the same workgroup\n\n2. Enable file and printer sharing on both systems\n\nThe configuration all depends on which operating system you are running.

No - you can't.  I think your talking about a modem, and not a router.  Was it provided by your Internet Porvider?  If so it's a modem and you cant use both connections.  Even if you could, your ISP would charge you for hooking up an extra PC that way.\n\nHOWEVER - What you can do -- is if one of the PC's has a network card and USB (the new laptop, should definitely have that) and its got windows XP, you can share the internet connection.  Hook the modem to PC1 with USB -- then rightclick "my network places" click properties.  You will see a list of networking devices on your PC -- right click the one that represent your modem hooked in with USB, and click properties.  In the window that pops up, click the "advaced" tab.  You will see a check box that says "share my internet connection" - click that and the wizard will lead you through setting that up.  \n\nThen use an ethernet cable to hook the PC's together, and viola.  This way your ISP will also never know about the other computer, cause it only ever "see's" the first one. \n\nWhen hooking the PCs together with ethernet cable -- it is important that it is a "crossover" cable and NOT a "patch" cable.  The ether net cable that came with your modem is a "patch" cable so you cant use it.  Most likely you will have to buy one.  \n\n(the other solution, is to buy an actualy router -- if your getting a new laptop -- it might be wise to buy a wireless router.  If you use a router (modem hooks to router -- router hooks to PC's)  your ISP will also never know that more than one PC has access.\n\n\nIf it is an actual router, then yes you can use both.  Note -- if it is an actual router it will have more than on ethernet port.  Virtually ALL consumer routers have 4 ethernet ports.   Since you said "So, THE ethernet port is free...", is the reason I am thinking you mean a cable or DSL modem

First, both computers need network cards, although most come with Ethernet these days.\n\nTo connect them, you have two options.  You can connect them directly using a crossover cable.  Simply plug the ends of the cable into the network ports on each computer.  If you plan to maybe add other computers later, get an Ethernet hub with 4 or 5 ports.  In this case, use 2 regular (not crossover) cables to attach the computers to the hub.\n\nPresto, home network.

If you have DSL you need to buy a Network Card.  If you use dial-up (such as AOL) you'll need a modem card.  They are called PCMCIA card or PC cards that connect in a slot on your laptop.\n\nNote:  If you have DSL and only one computer connected directly to your DSL modem you'll also need a router or hub that will allow you to connect both computers to your DSL at the same time.

you just need an ethernet network card in each pc and just connect with a crossover cable...........all cheap stuff........10-15 quid the lot          try this        http://www.homenethelp.com/web/diagram/crossover.asp

u can do it with diffrent devices\nthe best way is make a network bye connecting this two  computer to each other , u can contact me to explain u more

You can only use either the USB or the Ethernet port to hook up your entire home network.\n\nFortunately, your modem will act as a DHCP server. So, you can buy a $40 switch at any office supply / electronics big-box store, hook the computers up to the switch, then hook the switch to the modem, and both PCs should be on the Internet.\n\nSee this for more info:\n\nhttp://blog.360.yahoo.com/blog-NVb99sQ4RK5BVgIbxdcQdcRtfT8-?cq=1&l=16&u=20&mx=30&lmt=5&p=21

Easier than ALL the solutions proposed so far, buy yourself a *crossover ethernet* cable.  You can then connect the two computers via their ethernet ports.  Most computers these days have ethernet ports built in.\n\nThe crossover ethernet cable will allow you to have the two computers connected together into a 'hubless' network and they can share files, printers, ethernet connections, etc.  You just need to go into the Network Wizard and tell it you want to enable File and Print Sharing.  After that you can simply drag files into the shared folder on one computer and they will be visible to the other for copying.\n\nI'd give you all the nitty-gritty details, but instead of repeating things, I'm attaching a link to a very good article by Microsoft on setting up a home network.  The relevant section is under "Ethernet network - For two computers".\n\nAnd if you ever decide to upgrade to more computers, you can simply disconnect the two, add a router and a few more cables...\n\nNote: an Ethernet *crossover* cable is *not* the same thing as an Ethernet *patch* cable.  Be sure to tell the salesperson at your local electronics store that you want a *crossover* cable for connecting two PCs directly.\n\nI added another link to Radio Shack, in case you weren't sure what you should ask for.  You shouldn't pay any more than US$10 for a cable, perhaps even less.  Ask for Ethernet Cat5 or Cat5e, but be sure it is the *crossover* type, not the regular type.\n\nI see in your additional comments that you already have a network set up with a router and a wireless card.  If so, then you should already be set to go.  Just go to 'My Network Neighborhood' and look for the Shared Documents folder.  Put the file there, then copy to the other computer.
