how to set up a computer network-wireless-

Step 1
Assess your requirements. Make a list of all devices required for creating the network. These include wireless routers, wireless network adapters and nodes, switches or hubs, cable modem, wireless LAN cards for desktops and laptops, antennas, amplifiers, firewalls, wireless bridges and cables. Three types of wireless network technologies widely used are 802.11a, 802.11b, and 802.11g. All equipment you buy should support either of these technologies, preferably 802.11g — the best performing standard of the three. Some of the basic devices that you will require for setting up a wireless network and sharing Internet connection on all computers connected include a broadband modem (cable or DSL), a wireless router, wireless LAN cards for all desktops/laptops and/or wireless network adapter(s) (nodes).
Step 2
Connect your broadband modem to the wireless router. You could connect the modem with the router using a cord (Ethernet or CAT5).
Step 3
Connect the wireless router with the computers. If your computers have wireless LAN cards, you can set them up to communicate directly with the wireless router. If you do not have wireless LAN cards, you will require a wireless network adapter per computer. In such cases, the wireless router will communicate with the wireless network adapter(s), which in turn will be connected to each computer. USB network adapters are recommended. These can be connected to computers through the USB port. Other adapters require Ethernet cable.
Step 4
Connect all computers in the network to each other. Again, if your computers have wireless LAN cards, you can set them up to communicate directly with each other. However, if they are not equipped with wireless LAN cards, you will need a wireless network adapter for each computer. In such cases, the network adapter (preferably one that has a USB interface) can be connected to each computer and its antenna can be used for transmitting wireless signals.
Configuring All Devices and Computers
Step 1
Configure the wireless router. This can be done by connecting the wireless router to any computer. Usually, an Ethernet cable is provided with a wireless network. One end of the Ethernet cable should be connected to any of the ports of the wireless router (except for ports labeled Internet or WAN). The other end should be connected to the LAN port of the computer. Open your browser and type in the admin URL. This will be mentioned in the router’s user manual. It would also mention a login name and password required to access the router’s admin site. Once logged in, follow the instructions to configure your router and set up an SSID (a unique name for the wireless network).
Step 2
Configure each wireless network adapter, if any. If you have Windows XP installed on your computers, the system will automatically detect the network adapter as soon as it is connected. In other cases, you may have to install specific drivers. Ensure that you get a drivers’ CD along with the network adapter. Next, you may have to insert the installation CD to configure the adapter. The CD will take you through the entire installation process.
Step 3
Ensure that the broadband modem is configured for the Internet. It not, refer to the broadband modem’s user manual for the configuration process.
Step 4
Once the network devices have been configured, your operating system should show a wireless network icon in the status bar (at the bottom of the screen). The process of connecting computers to a wireless network may differ depending on the operating system installed. Refer to your operating system’s help file for details. However, the connection process in Windows XP (and most other Windows operating systems) is explained below.
Step 5
Click on the wireless network icon. A list of all wireless networks available should be displayed. This will include the wireless network you have set up. Look for the SSID entered while setting up the wireless router. If the network is not listed, refresh the screen or restart all devices.
Step 6
Click "Connect" after selecting the wireless network. You may be prompted to set up a network key (a password) for accessing the wireless network. This key is required by all users to connect to the wireless network.

how to set up a computer network

Step 1
Get a network adapter for each computer that does not already have one. A network adapter is a device that allows a computer to connect to a network. Every computer on the network will need one of these. Network adapters come in many forms, some connect to your computer by using USB (this is the easiest type to install), some use a 9 or 25 pin serial port, but usually only very old ones, and some connect to the computer by installing it inside the computer, which I will not discuss in this article because that is not another topic for another day and going into these details will require taking apart your computer to work on it's internal electronics. The type of network adapter most people use is an "Ethernet adapter". Most modern computers have an Ethernet adapter already installed from the factory.
Step 2
Get Category 5e cables. This is the type of cable that is used to connect computers using Ethernet adapters. Usually category 5e cable is a thick blue cable with plugs on the end that are similar to RJ11 US telephone plugs, except they are wider.
Step 3
Get a network router or switch. A network switch is a device that is used to connect computers together on a network. This will be at the other end of the category 5e cable from each computer. Only one is needed for a network of 4 computers or less usually, it all depends on what kind of router or switch you get, some allow up to 25 computers, but these can get very expensive, because the ones like this are commercial switches. A router is simply a switch that allows one network to be linked to another network through Network Address Translation technology (NAT), you will most likely need a router if you are using your network to share a single internet connection.
Step 4
Plug it in! Now that you have all supplies necessary to create your network, you can begin installing it! You need to first make sure your network adapters are installed on all computers. If all Ethernet adapters are installed, then it is time to plug in those category 5e cables to the router or switch! If you have a switch, then you simply plug in the one end of each cable to a plug in the switch, and the other end into the plug in the Ethernet card of each computer. However, if you have a router, it is important to determine which plug to plug things into. cables that are going to the Ethernet cards on the computers need to plug into one of the plugs on the router that is labeled LAN or Local or Network. Also, if you are sharing an internet connection, then you need to make sure you have a Cable or DSL modem that has an Ethernet output. When you find the Ethernet plug on your Cable or DSL modem, then you plug in one end of a category 5e cable to that plug, and the other end to your router. The cable or DSL modem needs to connect to the plug on your router that is labeled Internet or WAN or Uplink. I am unsure if dialup modems even support shared connections, as far as I know, no dialup modems with Ethernet output exists, however, there are ways to share a dialup connection over a network, but I will not discuss that in this article because that is another topic for another day.
Step 5
Because of the wide variety of different operating systems and the different methods of completing this process, the easiest way to complete this process universally, using any operating system or computer, is to restart each computer on the network. After they all boot, you should be able to use your network to do many things.
