1.Connect the second router to your modem. The modem should be connected to your computer. Make sure the router isn't connected to any other devices. You can leave your first router unplugged and disconnected for now.

2.Open your Internet browser and type "" http://192.168.1.1./" into the web address bar. This will bring up a router configuration page.

• You could use an address like "192.168.1.2" as long as it is not used by any other device. The addresses need to be different so the routers can communicate with each other correctly.  

5.Disconnect the second router from the modem.
    

6.Insert an Ethernet cable into an open LAN port on the first router and connect it to an open LAN port on the second router. Do not connect the cable to the Internet/WAN (wide area network) port of the second router.

• If you obtain a long Ethernet cable to run between each router, you can physically extend the range of your network. This works for both wired and wireless routers. Extending the range of your network will allow you to have devices placed further apart from each other, such as in a house or office.

• If your second router is connected with the Internet/WAN port, extra steps must be taken to achieve correct port forwarding. The first router must be forwarded to the second and the second must be forwarded to the computer.

• If you are using two wireless routers, the second router Internet/WAN setup will cause wireless devices to communicate improperly. If a wireless device gets too far out of the range of the first router it will be assigned to the second router and need a new IP address to work.

• Connecting an Ethernet cable from a LAN port on the first router to the Internet/WAN port on the second router can cause a number of communication problems. Computers or devices connected to the second router will be able to connect with computers connected to the first, but computers on the first router will not be able to connect with computers on the second.

Not only do many homes now include a personal computer of some type but some professionals will often have a desktop and a laptop. Emailing files between the two can become tedious, as can saving the files to an external thumb drive before connecting it to the other computer to upload. For this reason, it is helpful to have a quick and easy way to share files between computers. It's simple to connect a desktop to a laptop by creating a LAN, or local area network.

• Most modern computers will connect via Ethernet or Cat5 cable.

• You should be able to connect remotely to a wireless access point if your desktop computer is fitted with a wireless networking card.

• On a PC, right-click the file location you want to share file access to. For example, most documents are stored under the "My Documents" hierarchy.

• Click "Share" from the drop-down menu.

• You can add existing user IDs to the list of those who may have access. If you are the only one who has a user account on your PC, you can skip this step.

• Click the Share button and wait a few moments for the process to finish. Click the Done button when it becomes available.​​

• Open the home Network and Sharing Center from the computer to which you want to copy or transfer files.

• The Network and Sharing Center is available from the Windows Start menu on computers using the Windows Vista and Windows 7 operating systems.

• Click the computer name that is currently housing the files.

• When prompted, enter the user name and password for your account on that PC.

• Choose the Sharing option from the View menu.

• Click the plus sign icon in the Shared Folders window and browse to share folders tow which you need access.

• Add each folder and designate any other users that will have access.

 

• It is possible to use file sharing cross-platform between a Mac and a Windows-based PC. Share files as usual on both computers. In the Mac sharing options, also allow sharing protocol Server Message Block (SMB). Pass the files back and forth from the Mac machine.

• If Sharing with an OS X Mavericks computer by default SMB is enabled.

• Sharing your files over an open and unprotected home network can be dangerous. Be sure to only use a security-enabled network and to password-protect all systems with shared files or folders.

• Desktop computer

• Laptop Computer

• Ethernet cables or wireless networking cards

• Modem, router or gateway

• Internet access

Digital data can be moved from device to device quite easily, but it requires a tool to do so. There are numerous tools that can perform a file transfer. Depending on their speed and size, these tools can range in price. If you need files moved from one laptop to another,though, you will need some kind of vehicle for the process. Use the steps below for various methods of transferring files between laptops.

• Open your email page and start a new email message.

• Set the receiver of the email as your own email address.

• Attach files to the email by clicking "attach file" within the email message.

• Choose a file from your folders.

• Continue to attach more files as needed and send the message when you've finished.

• Open the email on a different computer and download each attachment.   

• Place a USB drive into the first laptop and open the folder that automatically appears on your desktop.

• Open the folder that contains the information you would like transferred and copy or drag that data into the USB drive folder.

• Eject the drive using your laptop's proper procedure.

• Connect the USB drive to the second computer and copy the contents to the desktop. Place the data in the proper folders once it has been transferred.

• Visit a file storing/sharing website online. These services can be free or cost money depending on the security and space provided by the site. Most of these services allow you to upload your computer's contents onto the site's servers and download that information whenever you would like on whatever device you own. These services are often used as a way to back up computer information in case of a hard drive crash.

• Connect your Mac laptops using a special cable for transferring data. These cables can be purchased at locations that sell Apple products.

• Follow the Firewire data transfer directions to move information from one laptop to the other.

• Buy an external hard drive with as much space as you need. External hard drives can range from less than 500 GB to as much as 5 TB.

• Connect the external hard drive to the first computer and copy the information onto the drive using a wizard.

• Remove the hard drive and connect it to the second computer to copy the contents.

• Visit public FTP sites by typing ftp:// and then the site from which you are transferring data.

• Browse the FTP directory and click a file to download it. You might need to "Save Link As" to save it to your computer.

• You can find public FTP sites by doing an internet search from your favourite web search engine. This will help with Step number Two

• You will not be able to attach every file on your computer to an email. Most email services have limits on the amount of data you can send and receive.

• Do not disconnect a USB drive without first ejecting it. Your files could become corrupted.

• 2 laptops

• Firewire cable

• External hard drive

• USB drive

• Go to a reputable computer supplies store or online retailer and buy a special data transfer cable. Explain that you need a USB cable to connect the two computers and ask for recommendations.

• Install the drivers on both PC and plug in the cable according to the instructions.   

 

• Follow the steps to configure the USB settings on both computers so that they can communicate with each other.

How to Connect Two Computers Using USB

• Note that this type of connection can be more difficult to set up and manage; where possible, connecting via ethernet is probably a better option.

• Never try to connect two computers with the so-called A/A cable that has no converting electronics inside (just a plain cable with matching connectors). It connects input to input and output to output, so can easily damage the hardware.
