    I'm fairly sure you can simply directly connect them for a direct connection. Otherwise, you'll need a hub or a switch or a router (last one for internet capabilities).

    If your going to hook up the two computers directly you need a crossover cable.

    You can "beam" data through infrared ports if you have those on both laptops (I think). Not sure whether you need a LAN in place to do that but I am guessing you don't. I don't know about USB.

    I'm pretty sure you can network two computers through USB, although I don't know how. There might even be instructions somewhere in your OS telling you how to do it.

    On the other hand, it's incredibly simple to do it using a router. You don't even have to know what you're doing, as the installation disc guides you through the process.

    Do you need a DSL modem in addition to a router? Can you set up a LAN completely isolated from the Web? (I suspect the answer is "yes.")

    You can use Bluetooth to network Macs without a router or a modem, providing both computers have Bluetooth capability and the Airport network card installed (which comes internally on all new Macs, but I don't know how long that's been the case). I'm not sure how you would do it on a PC, but it seems like the hardware would at least be enough, and you'd just need the right software to do it.

    of course you can, just buy a switch or hub. and connect (assuming you have network cards installed on your computers) your pc's into the switches / hubs using ethernet cables (straight through)

    If you leave your NIC's to auto-configure you will get an APIPA IP address, which will allow you to communicate between your computers using IP... If you have netbios/netbeui installed you will be able to communicate between your computers using the computer names...

    Simple hubs are basically dirt cheap, but the problem as I see it is the fact that most dealers don't want to carry those these days. They want to sell you the expensive stuff, where they can make their profit. I had a simple, cheap hub, but when it went South I found getting a replacement a problem. Everybody wanted to push wireless stuff, etc.

    It is very easy to conncet lan between two laptops, The thing is is you just need a cross wired cable. you can easily get the cable wiring diagram from google. Then you will go to your network conncetions and select option (obtain ip automatically) if it is not connceting then also then you give ip like follows in both computers.
    computer 1: ip 192.168.1.100
    subnet mask: 255.255.255.0

    computer 2: ip: 192.168.1.101
    subnet mask: 255.255.255.0

    Then it will automatically connect each other. not need any hub or router. if you have any doubts you send me message i will help you

    Is this an Ethernet cable? Are these examples of such cables? If not, can you post a link for an example? Many thanks.

    You should also point the default gateways at one another.. I have seen on many occations Windows get confused when you dont do this. In theory you shouldnt need to but in practise you do

    I set up LANs at work and at home.

    The DSL/Cable modem -(RJ45 cable/wire)-> router -(RJ45)-> PCs (NIC).

    I use Linksys routers had have had great experience.

    Then set up a workgroup - same for each PC.

    A printer can be local or networked - I have installed the printer as local on one PC and then it is a network printer for the others.

    If done correctly, file sharing and printer across the network is simple. Each PC accesses the internet through the router, so you don't have to pay the ISP for multiple PCs.

    A LAN is a "Local Area connetion". In Cisco speak it sits at the access layer of an Infrastructure.
    What you just described there Astronuc is not a LAN, but a WAN link to a single end node.

    To create a LAN all you need is Network enabled devices, a Hub or Switch, Ethernet cables and some means of configuring the Network addresses so they can communicate using IP.

    Thats it, you dont need a DSL modem, or a Router.

    Thanks for the clarification.

    I started with a Linksys hub and then replaced it with a router. I thought it was still a LAN. All the PC's are in the same working group. I think even some of the literature I use still refers to it as a LAN. All I know is that the PC's communicate with each other, and each can access the internet independently.

    the other day, my kid was messing around with my laptop and after that when i tried to connect to the internet using my broadband cable the web browser would keep saying no connection found. So i opened up my network connections and found that the LAN network was missing. After that i tried to create a new one but couldn't. So could anyone direct me in the correct direction. Thanks

    Call your ISP's tech support and have them walk you through the correct settings. They should be open 24 hours a day. If not, get a better ISP.

    Yep. That's the right cable.
    Good for connecting two machines.
