In this guide I will try to explain how to connect 2 laptops together, without using crossed wires and without having a wireless router, to transfer files from one handset to another and to share the internet connection of one of the two for you can navigate on the internet.
The typical situation can be this.
I have a laptop connected directly to the Internet using an ADSL modem with Wireless network adapter for wireless connections.
My brother bought a new laptop and want to use the Internet too.
The ideal solution is to spend money and buy a wireless broadband router, use one pc as a router.
If you have a desktop computer that has no fixed wireless adapter, you can buy a USB wireless adapter for less than 10 euros and is much cheaper than a router.
Here's how to share your Internet connection from laptop or desktop computer that has a wireless adapter and create a real network of PCs that can surf the internet together.
In another article we saw how to connect two PCs with wifi without internet connection only for exchanging files.
With Windows Vista and Windows 7 is really simple to connect 2 or more computers together using the wireless network.
So, if you need to connect a Windows pc XP and one Vista, it surely configure Vista as server computer that is connected to a network that shares its connection, while XP is the client that connects to the network through the Vista pc.
If you want to connect multiple PCs together who share the same connection and files, one that has Vista can act as a Host while everyone else become clients that use the shared connection.
HOST means that the computer is directly connected to the Internet via ADSL modem and the network that must be shared.
To configure the computer with the Windows Vista operating system that will act as a wireless access point, you can follow the following steps:
1) press the right mouse button on the small icon indicating the 2 small computers, bottom right on your desktop, and select the last entry, the network and sharing Center.
2) on the right side click on set up a connection or network.
3) Choose "set a wireless ad hoc (computer-to-computer) network" and click Next.
4) a window appears that says something like: "an ad hoc network (computer-to-computer network) is a temporary network used for sharing files, presentations, or an Internet connection among multiple computers and devices. Computers and devices in ad hoc networks must be within 30 feet of each other. If the pc is connected to a wireless network, you may be disconnected when you set up this kind of network. "
Click on next.
5) now Enter any name, select the security type and enter a password. (For example I write pom-network name, WEP as security protocol and password 12345) and reclick on it next.
At this point you can decide whether to save the configuration for it reusable afterwards or not; If you do not save, to reboot you will have to reconfigure it again.
6) once you have finished configuring, Vista will tell you that the network is ready for use and, in the lower part of the window, you can enable internet connection sharing.
At this point ended the phase of setting up the server, i.e., of the pc that is sharing the connection will allow others to go on the internet doing from through.
As you can see, the wizard is very easy, now then, let's see how to connect another laptop with Windows XP or Vista.
From any pc with a wireless network card, making scanning of available networks, you should see the ad-hoc connection you created earlier.
Next, select the network you created earlier (the pom-network) and click Connect.
If the network to which you are attempting to access is an unsecured network, simply select "connect anyway" otherwise you enter password (12345) and you click on "connect"
You should then see a message that notifies the connection successfully.
At this point, you can begin to surf the Internet and access the shared files on other computers connected to the ad-hoc network always remembering that the Host computer must be approximately 9 metres from the pc that is sharing the connection otherwise it falls all over!
If the host server must be a Windows XP pc the procedure is described in article Share the Adsl wireless home Internet on pc and mobile phones with Wifi.
If it is Windows 7, you can create a hotspot with your computer with a really simple method which does not require ad hoc connection.
