I can't get my wireless network off the ground. I want to use the Internet, share files, and so on, but none of it seems to work. I thought this was going to be easy!
Wireless networking is easy! (Unless it's not.)
Wireless networking can be extremely convenient when it works but an absolute headache when it doesn't. The good news is that if you take the time to set up your router correctly, update your firmware, and install Service Pack 2, most wireless problems will disappear.
Note: If you don't have Service Pack 2 yet, use the Windows Update feature now to get it (open Internet Explorer and select Tools --> Windows Update).
A router lets you connect your PC (or all the PCs in your workgroup) to the Internet, as well as connect multiple PCs to each other. Routers also include built-in firewalls, offering much better protection than software-based firewalls such as the Windows Firewall built into Service Pack 2.
But most importantly, a wireless router acts as an access point, a central hub to which all wireless devices in your home or office can connect. To set up a wireless network, you'll need a wireless router (preferably one that supports the 802.11g standard), and at least one PC with a wireless network adapter.
Connect your PC directly to your wireless router with a cable; that's right, a cable! You'll need to communicate with your router to set it up properly for wireless access something you won't be able to do wirelessly throughout the whole process. Connect one end of a category-5 patch cable to your PC's Ethernet port, and the other end to one of the numbered LAN ports on the back of the router. Then plug in the router's power cable.
Your router probably came with setup software on a CD; in most cases, you don't need this and can use the router's more flexible web-based setup instead. Open a web browser on your PC, and type the router's IP address (usually 192.168.1.1 , but check the router's manual) into the address bar. The router's built-in web server should show you a setup page like the one in Figure.
If you can't connect to your router, your computer is probably not on the same subnet as the router. The first three numbers of your computer's IP address must match the first three numbers of your router's IP address, but the fourth number must be different. For instance, if your router's address is 192.168.0.1, you may not be able to connect to it until you manually change your PC's address to 192.168.0.xxx, where xxx is any number between 2 and 255. If all else fails, reset the router, following the instructions in the documentation, and try again.
On the setup page, choose your Internet connection type from the list. If your Internet connection requires a username and password, select PPPoE. If your ISP has provided an IP address for your connection, select Static IP. Otherwise, choose Automatic Configuration -DHCP. (Naturally, the options for your router may be slightly different.)
Click the Apply or Save Settings button at the bottom of the page when you're done. Within a few seconds, you should have Internet access; go ahead and test it by opening a second browser window (press Ctrl-N) and visiting any web site.
Note: If you select PPPoE, the router should prompt you for a login. Type the username and password for your broadband connection, not your login for Windows, your email account, or anything else. If you choose Static IP, enter the IP addresses of your ISP's DNS servers. Your ISP should provide this information to you .
Once your Internet connection is working, visit the router manufacturer's web site and download any available firmware updates. (You can usually find your router's current firmware version on the Status page in the router's web-based setup.) Firmware updates include essential bug fixes,
performance enhancements, security patches, and occasionally new features. Consult your router's documentation for firmware update instructions.
Next, go to your router's wireless setup page (see Figure): this is either a link in the main menu or a tab across the top of the page. Choose a new SSID (the name for your wireless network), and turn off the Wireless SSID Broadcast option to keep your wireless network private Click the Apply or Save Settings button at the bottom of the page when you're done.
Note: If you're using a Wireless-G router (a faster sibling of the 802.11b standard, capable of 54 Mbps), avoid the temptation to select the "G only" option on the wireless setup page. This feature prevents slower Wireless-B devices from joining your WiFi networka fact you'll likely have forgotten when a visiting relative tries to connect to your home network to check her email a few months from now .
You should also enable encryption for the best wireless security. This setting will be accessible either through a button on the current page, or on a separate tab entitled WEP, WPA, Encryption, or simply Wireless Security, like the one in Figure. WEP, the Wireless Encryption Protocol,
prevents anyone without your secret WEP key from connecting to or spying on your wireless network. Some routers also support WPA, or WiFi Protected Access, which provides a slightly higher level of security.
On your router's encryption page, enable WEP, and then choose the highest WEP encryption level supported by your router (in this example, 128-bit). Higher levels provide better protection, but also mean longer (and harder to type) WEP keys.
Some routers have you choose a passphrase , which is a word your router uses to generate the WEP keys. In the example shown in Figure, I typed the word "annoyances" and clicked the Generate button to create four 26-digit WEP keys (the first one, Key 1, is the only one that is used). Generally, all of the computers on your wireless network will have to use the same key.
Your SSID is the back door into your wireless network. If you broadcast your SSID, anyone with an SSID sniffer will be able to find it in a matter of seconds, connect to your network, and use your Internet connection (or even snoop around your shared folders).
The same danger exists if you continue to use your router's default SSID; probably a million people around the globe are using "link-sys," which makes it a good guess for anyone trying to gain access to your network. Choose an SSID like you'd choose a password, and your wireless network will stand a better chance of remaining private.
The only time you'll likely want to enable SSID broadcast, other than for testing purposes, is if you're setting up a public WiFi access point, say in a coffee shop or bed and breakfast, and you want to make it easy for your patrons to connect.
