First of all, you have to check to make sure that your other LAN cable is a straight cable. Otherwise you can swap LAN cables between this 2 PC to connect to the router.\n\nThen when you boot into Windows, go to Start > Run > Type cmd > Click OK. Do a "ipconfig" in DOS prompt and see if your 2nd PC gets an IP address from your router.  You can do likewise on your 1st PC to see what is the gateway of your router. Then verify the information on your 2nd PC. If the numbers are not right, you can type "ipconfig /renew" and let your 2nd PC get a new IP address from the router.

Assuming you got Windows XP do the following.\n\n1. Plug CAT5 cable into the router.\n\n2.  Plug other end of cable into your PC's LAN port.\n\n3.  Turn on computer.\n\n4.  In My Computer change your workgroup name to whatever the workgroup name on your network is.\n\n5.  Restart your computer.\n\n6.  You should now be connected to the network and other computers should at least be able to see you.\n\nNow if you want to share files and give other PCs permission to access to your computers, there's a little more customization involved.

Ok what you will need is a crossover cable. You them plug the cable into your laptop and desktop. You go to control panel and go to network connections and enable the connections on each computer. Right click on the two computer logos in the bottom right corner and go to repair. They should connect now, then just go to my network places and you should see your computer. Now all you need to do is right click the folder you wanna share and right click and go to shareing and enable. This should work but u might have issues. Hope this can help you. (if you cant see your laptop, go to my computer and right click and go to properties and then go to computer name and change, and you will see the domain name and check if they are the same, if not change to the same name..

If you mean you want to network your two computers together using a USB cable, you can just use the networking wizard at Start --> Control Panel --> Network Connections. \n\nIf they're hooked together, they should see each other via your A-to-A cable.

Windows allows internet connection sharing.  Enable this for the network connection of the computer which is online.\n\nA better solution is to hook up both computers through a router.  These can be purchased for under $50 online or in walmart/target/radio shack/etc.

The best and safest way for you to network your two PC's is to purchase a router with 4 port switch.\n\nUse one PC to follow the router setup wizard.\n\nYour ADSL modem will connect to the routers WAN port and the to PC's will connect to two of the routers LAN ports.\n\nOnce you have one PC successfully connected to the internet through the router use the Windows Network Setup Wizard to create your local area network.\n\nGo to Start > Settings > Control Panel > Network Setup Wizard\n\nNext > select "This computer connects to the Internet through a residential gateway... > Next > give each PC a unique name > Next > Provide the SAME workgroup name for both PC's > Next > select Turn on file and printer sharing > Next > apply these settings > Next.\n\nEach PC should now have a unique name and belong to the same workgroup.  Each PC should also have Network Share folders under My Computer.  This shared folder should be visible from the other PC.\n\nTo share a specific folder on a PC go to Windows Explorer > select the folder to be shared > Right mouse click > select Sharing and Security > and follow the directions for the type of sharing you want.\n\nTo find the other networked PC go to: Windows Explorer > My Network Places > Microsoft Windows Network > [your workgroup] > and all your networked PCs associated with your workgroup should be visible.  You can now expand the PC to see what folders and devices are shared.

Just wipe out the network connection and set the network connection all over again. It should erase everything associated with your workgroup and let you recreate it.

go into your hardware manager and look for the wireless lan card option. right click then properties at the bottom of that window should be a disable or enable option if that doesn't work then you need a new lan card\n(also if you have the radio mast symbol on your laptop on the keyboard press and hold FN and then press the mast button that should re-activate it.

the cheapest way is to connect two computers directly together using a cable.  To do this you will needa Network Interface card (NIC) in both computers (most new computer come with them as standard but if not they are cheap).\n\nbuy a CAT5e (crossover) patch cable and plug each end into the computers NIC cards. If your using XP you can run the "set up a home or small office network". This wizard will do all the work for you.\n\nenable internet connection sharing on the computer that conects to the internet and bobs your mothers brother :-)

Use a router and network cards. Visit http://en.wikipedia.org/wiki/Router for more info.  Or you can use a hub which will split the connection as well.
