Installation of your Wireless Network

0

From hardware to software, it’s all just a matter of following some simple steps and remembering a few simple rules to go about installing your wireless network. Read on to find out how to get your wireless network up and running.
Setting Up Wireless Access Points
We will consider two scenarios for configuring an Access Point.
The first is where you just have a plain-Jane Access Point. The other is where the Access Point has a wireless broadband router with either cable or DSL or dial-up modem built in.
Connecting Two PCs Using An Access point
To connect two PCs wirelessly using a simple Access Point will need you to connect the Access Point to one of the system directly where you have the Internet connection coming in. This PC should have a Network Interface Card (NIC). The other machine should have wireless PCI adapter. An RJ45 cable is provided with some of the available Access Points.
Follow the steps as below to get an Access Point up and running:
1. Switch off the PC and connect the RJ45 cable to the Network Interface Card of the PC.
2. Connect the other side to the LAN port of the Access Point.
3. Power up the Access Point and make sure the LED indicates that everything is normal, as mentioned in the manual.
4. Now power up the PC and get the LAN on the same IP range as the Access Point is. The default IP address of the Access Point will be mentioned in the quick setup guide on the CD. A typical IP is 192.168.1.1 and a the corresponding subnet mask would be 255.255.255.0. If this is the IP of the Access Point, then give the LAN an IP something like 192.168.1.2, up to 254.
5. Once the TCP/IP settings are configured, it is time to ping the Access Point to check whether everything is working properly.
6. To ping, click Start > Run, and in the dialog box, type in “ping
7. If the ping commands works successfully, launch your browser and type in “http://”, for example, http://192.168.1.1, in your browser address bar, and press [Enter].
8.This will let you access the Web server of the Access Point, which has an inbuilt utility that will let you configure the Access Point according to your need. From here, you can change the SSID, IP/Subnet mask and enable or disable wireless security.
9.Do the necessary changes, and that’s it. The Access Point is configured.
Now, go to the other system, which has a PCI Wi-Fi card plugged in to it, and make the following changes.
1. Switch off the system and plug in the PCI wireless card. Now turn on the system and let the card get detected by the system.
Install the necessary device drivers and the configuration utility provided with the card. Restart the system to complete the installation process.
2.Now launch Control Panel and go to ‘Network connections’. The window that opens will display ‘Wireless Network Connections’. Right-click it, and click properties.
3.Now scroll down to the TCP/IP connection, and click once on it to highlight it, and then click properties. This will open the TCP/IP dialog box. Here, you need to assign an IP to the wireless card with the first three metrics, which in our case is 192.168.1. This should remain the same, and the last one can be any number between 0 and 254—but not the same as the one already assigned to the Access Point and the first system’s LAN card.
4. Click OK to close the dialog box, which will bring you back to the Wireless Network connection properties. Again, here, click OK, and that’s it.
This is all the settings that are needed to get two PCs to connectwirelessly using a simple Access Point. Share a folder on the master system where the Access Point is connected, and try to access it from the client system—it should work.
Connecting Two PCs Using A Wireless Router
Wireless routers are Access Points that have the Internet port for a DSL or cable modem connection, and in most cases, also has a 4-port switch. A wireless router is useful only when you have DSL or cable Internet at home, or if you are planning to connect one of the PCs or network printers to one of the ports on the switch. However, if you have DSL or cable Internet, a wireless router is the best solution as it doesn’t require you to connect it directly to the PC to share the Internet connection, or files and folders on another PC. Here is how you will have to go about getting it running.
1. Connect the incoming DSL or cable connector, which is an RJ45 cable, to the Internet port of the router.
2.Power up the wireless router and observe whether all the LEDs are behaving in the exact manner as mentioned in the manual. If not, try resetting it.
3.Now go to the first system, with the wireless card plugged in. Get the wireless card on the same IP range as the router is. You can learn about the router IP from the manual.
4.Once the wireless card is configured, try to ping the IP address of the router and see whether the response is positive. You can also try to search for the available network, either by using the wireless card’s utility, or by right-clicking the network icon in the system tray and clicking ‘View available Network’. This will show you the active wireless network available.
5.Once you get your router detected by the wireless card, launch your browser and type in your router IP address in the following manner: http://. Press [Enter].
6.This will launch the configuration utility of the router. But to enter this utility you will have to provide a username and password, which again, is provided in the manual.
7. The first thing you should do now is change the login and password to something really difficult, which no-one can guess. Also change the security setting to at least 128-bit if you are going to access your bank account and other sensitive information.
8.You can and must change the IP address to something else, as the default IP is easily traceable, and known to most Wi-Fi users. If possible, restrict DHCP (Dynamic Host Control Protocol) to very few numbers. For example, if you are going to connect just one more system wirelessly, than restrict the start and end IP to accommodate just one machine. Change this later if you have to add one more system.
Setting Up Wireless Networking (Windows + Mac)
Configuring the Client
The adapter card will have to be installed on the client PC, since we’re going to connect the client machine to the Access Point configured on the LAN.
Here are the steps to follow in order to configure the client PC and the laptop.
1.Power down the system and remove the side cover. Locate a free PCI slot if you are going to use a PCI Wi-fi card. Secure it tightly, screw it in, and attach the detachable antenna to the card.
2.Power up the system. The PC will detect the card and ask for the drivers. Install the drivers as mentioned in the manual and restart the system if need be.
3.You’ll see a small icon sitting in the system tray once the drivers are properly installed and the hardware properly detected. Double-click the adapter card configuration icon in the system tray. This will launch the configuration utility.
4.Here, you don’t have to do anything, as most of the settings, including SSID and the encryption key, are automatically picked up by the adapter card. Select the Ad Hoc mode if connecting to the other PC or laptop configured in Ad Hoc mode. Give an SSID different from the one assigned to the other wireless card.
5.Check the signal strength available at the place the wireless desktop or laptop is placed by double-clicking the utility in the taskbar.
Setting Up Ad-Hoc Mode
Ad-Mod or Peer-to-Peer mode as it is commonly known is very easy to set up. It has multiple advantages: you can quickly create a network between notebooks that are Wi-Fi enabled, and share small files during a meeting. It doesn’t need an Access Point, as one of the notebooks can be turned into a soft Access Point, and the rest can connect to each other through it. Here is the stepwise explanation of how to turn a Wi-Fi enabled notebook into a soft AP, and to configure the rest to connect to it. We will use Windows to get the network up and running.
1.To set up the soft AP, click Start > Connect To > Wireless Network Connection. This will open up the Wireless Network Connection Dialog box. Here, click Properties; a new dialog box will open, from where we need to assign various settings.
2.In this dialog box, under the ‘General’ tab, scroll to ‘Internet Protocol (TCP/IP)’ and select it. Now click ‘Properties’, which will take you to the next dialog box where we assign the IP. Just assign the IP and click on the subnet mask once—it will appear automatically.
3.Close this dialog box and then click the second tab—’Wireless Network’. Here, at the bottom, click ‘Add’, which will launch another dialog box where we need to assign a name for Network Name (SSID). Check ‘WEP’ and ‘Key provided automatically’ for the rest to seamlessly connect to this AP. Press OK once through with these settings. Now click ‘Refresh’ in the ‘Wireless Network’ dialog box, and the network name will appear in the ‘available networks’ area.
4.Configure the client systems that will connect to the soft AP, and eventually to other client systems through it. For this, go to the ‘Network properties’ dialog box and assign an IP in the same range. For example, if you assigned 192.168.1.1, assign 192.168.1.2 and so on to the other client systems. Now click on ‘Subnet mask’, and it appears automatically.
5.Right-click on the network icon in the system tray. This will launch a dialog box that will display the name of the soft AP. Check ‘Allow me to connect to the selected network’. This will highlight the Connect button at the bottom. Just click it, and you should be able to connect to the other machines.
Repeat the exercise with the other client machines, and you will be able to connect each to the other, all without an Access Point.
Sharing An Internet Connection
If you are going to use wireless router with a DSL or cable modem inuilt, you will not have to use any third party tool like SyGate.
To share an Internet connection between two or more systems using a wireless router, you will need some information handy, like PPPoE (Point to Point Protocol over Ethernet), your user name and password which is provided by the ISP, subnet mask, default gateway, and so on. When you log in to the Web server of the router, you will be asked to give this information. If the broadband router asks for any additional information, you will have to get it from your ISP. Once you have provided all the necessary information, use the test button to check whether you are able to connect to the Internet.
Optionally you can set up your DNS servers either to OpenDNS as 208.67.222.222, 208.67.220.220 or Google’s DNS servers as 8.8.8.8, 8.8.4.4 to enhance the performance of DNS lookups.
