Ways to Connect Two Computers to Share Data

I am guessing that you have two computers at home and you are tired of transferring data from one to the other, through external storage devices. You may even be thinking of connecting the two of them together, for ease of using resources like printers or for multiplayer gaming.

Connect Using an Ethernet Cable
One of the simplest ways is the use of an Ethernet cable. For this networking method to work, you need to have a network card installed on both the computers. These cards are placed in the PCI slots of the computer. The card provides an Ethernet port to the computer, which provides a facility to connect it with other computers.

So, to connect two computers together using an Ethernet cable, make sure that both of them have a networking card and if they do not, then buy them and get them installed. Choose a network card which provides high data transfer rate. Buy an Ethernet cable. Plug one end of that cable into the Ethernet port of the first computer and the other end into the port of another computer. Make sure that you connect the cable properly, into the Ethernet port and hear it clicking into place on both sides.

Next, you must switch on the two computers and go to the network settings. I am assuming that you have a Windows operating system installed. In case you have any other operating system, run its equivalent network setup utility program.

Create a network using the ‘set up advanced network’ option, by logging in as the administrator. Make sure that you don’t forget to specify that you are creating this network without a router and directly connecting computers. Name the computer you have logged in as the ‘host’, while the other computer should be named as the ‘guest’ and do the same on the other one.

If you are asked to create a network setup disk, then create one and run it on the other computer to transfer the network settings. Turn file sharing ‘on’, when given a choice. Click on properties of drives or folders and enable their sharing on the network. That should do the trick and enable your two-computer network.

Connection Using a USB Cable
You can connect the two computers by another method, which is by using a USB cable. Here is what you need to do. First, you need to install the driver software for the USB cable. Insert the installation CD in the drive of one computer and finish the installation.

Choose ‘Link Mode’ in the installation process, which enables you to transfer files between the two computers. If you choose the ‘network mode’, it will connect the computer on a network. Repeat the procedure of driver installation on the second PC. Then connect each end of the USB cable, to the USB ports of each computer. With that done, your computers are linked for data transfer.

There are many other ways of connecting two computers together through the use of a router based IPV4 network. You can set up such a network at home and enjoy multiplayer gaming.

How to Make Private Wifi Antenna

download (2)Commercial Wi-Fi receptors cost you a bomb. There are alternate ways to make a Wi-Fi antenna at home that will not only increase the range of your network, but will also be very inexpensive. An antenna is nothing but a directional waveguide device that converts electrical power to radio signals, and vice-versa. Hence, pretty much any material that is capable, or can be made capable, of this function can be used as a Wi-Fi antenna.
A ‘cantenna’ is a directional wavelength reception device for long-range Wi-Fi. Ideally, a cantenna’s periphery is not strong enough to receive signals all by itself. Hence, cantennas are mostly used to extend a wireless network’s range or to improve reception over a distorted signal path. A cantenna can also amplify signals from 5 – 22 dB. While a ‘Pringles’ can is widely used for such setups, it is important to note that these cans are narrow in diameter and inappropriate for 2.4Ghz. Hence, for such a project, always use a can about 3.5 to 4 inches in diameter and approximately 6 or more inches in length.
Building a Homemade Wi-Fi Antenna using a Can
Materials and Tools
~ Can (about 3.5 inches in diameter)
~ Solder paste
~ 1.5 to 2 inches length thin copper wire strand
~ N-female chassis mount connector
~ Pigtail cable
~ Duct tape
~ Tripod stand
~ Drill machine
~ Soldering iron

  • Drill a hole in the can about a couple of inches from its base. Widen the hole according to the connector’s diameter.
  • The connector should just fit in; the hole should not be too small to get the connector in, nor too big so the connector falls off.
  • Set the adapter in the hole firmly.
  • Make sure it is set like how it is displayed in this image.
  • To the connector’s inside end (inside the can), solder a copper wire strand.
  • Be very careful when you solder the copper wire strand. This is how it must look like.
  • Plug in a pigtail cable into the connector outside the can.
  • Connect the other end of the pigtail cable to the Wi-Fi device/card. This will work only if you have a compatible Wi-Fi adapter. Hence, before proceeding, check the connector and adapter compatibility.
  • Mount the can on the tripod using duct tape, facing the Wi-Fi adapter. Once mounted and steadfastly in place, rotate the cantenna on its axis slightly, and adjust its tilt to work out the position in which it receives the strongest signal. This antenna has linear polarization, i.e., its rotation affects signal strength, positively or negatively. The tilt, though, is required in only very rare cases, and should be done carefully and only if necessary.
  • Once you shift the cantenna’s position to gain optimum signal strength, you can use your homemade Wi-Fi antenna!

Building a Homemade Wi-Fi Antenna using a Strainer
~ Strainer
~ USB Wi-Fi adapter
~ USB extension cable (at least 15 feet in length)
~ Duct tape
~ Wooden stick
~ Tripod stand

  • Using the USB extension cable, connect the Wi-Fi adapter to your computer. The cable’s female connector goes in your computer and the Wi-Fi adapter is inserted in the cable’s male port. If you haven’t found an extension cable long enough to position the antenna where you need, connect multiple cables together.
  • Using duct tape, attach the USB adapter to the handle of the strainer. If the strainer does not have a handle, attach a wooden stick to it using duct tape, and tape your adapter to the wooden stick.
  • Make sure your dongle is at a point where you receive signals at maximum strength. Temporarily place the dongle on the handle of the strainer and shift its place around the handle to find the hot spot.
  • Aim the strainer towards the Wi-Fi transmitter in a straight line and straddle a little to the left or right depending on where you are getting the best signals. Once you have figured out the exact spot which generates best strength of the Wi-Fi signal, mount the strainer on a tripod stand and get ready to use your strainer Wi-Fi antenna!
