Configuring A Wired Or Wireless Router

The next step in router setup is to configure your wired or wireless router.

NOTE: If you are using a Static IP address, before you can begin configuring your wired or wireless router, you will need to get some basic information from your ISP. You will need the following:

• Internet IP Address - This is the IP that the router shows to the Internet.
• Subnet Mask
• Default Gateway
• DNS (Domain Name System) Server IP Address

If you are not using a static IP, and most home users will not be, continue on.

Router Configuration

Configuring your router will allow you set up security and get everything set to connect to the Internet.

Note: The Linksys routers that I recommend come with a setup CD that includes a setup wizard. The instructions that follow are not for the wizard, they are step by step to configure the router manually. If you wish to use the wizard, refer to your manual for instructions to do this. The instructions that follow are also following the setup for a Linksys wireless router, but most routers will be similar in setup.

1. Open your web browser and connect to the administration page. To do this, simply type in the following address into your web browsers address bar: 192.168.0.1, or 192.168.1.1. If neither of these works, refer to your included manual on the correct address.
2. When you get to the router's home page, you will be asked for a username and password. Normally this is blank (as in no username) or administrator or admin, with a password of admin or password, but may be different. Refer to your manual for the login and password.
3. You will normally see multiple tabs on the top of the page. The ones we will concentrate on are:



• Basic - This is where you will enter your internet settings from your ISP.


• Administration - This is where you will find the management tab to change the password.


• Wireless - This is where you will setup your wireless settings and security.

Most home users will use the Automatic Configuration - DHCP setting on this page. However, if you are using a static IP, and have the information from your ISP, this is where you will enter it. In the Internet Setup section, select static IP and fill in the Internet IP Address, Subnet Mask, Default Gateway, and DNS Server IP Addresses. You may see some other connections in this area, but they are not important for basic setup. Refer to your manual for more information on them.

There are 2 optional settings in this area that may need to be configured - MTU (Maximum Transmission Unit) and Host Name and Domain Name. Most home users will not need to set these. Your ISP can tell you if they are needed.

On the administration tab you will see a management section. This is where you can change your password. It is highly recommended that you change the password from the factory default. Change it to something that you will remember. Enter it in the password field and in the confirm password field.

If you do not have a wireless router, you can skip this section. There are 2 main sections here to setup, basic, and security.

Basic

• Network Mode - If you are running multiple standards on your network, such as 802.11g and 802.11b, set this to mixed. Otherwise, select your standard from the dropdown. The standard you use will be determined by your wireless card, or the built-in wireless connection on your laptop.
• Network Name (SSID) - This is the name of your network. This is what will show up as the wireless router's connection name. The default is linksys - you should change this to a unique name.
• SSID Broadcast - When wireless clients search the area for an available connection, they will detect the SSID of the router. To broadcast the SSID, leave the default of enabled. To prevent your router from broadcasting, change it to disabled. Most home users can leave this to enabled.

Security

WEP / WPA - Setup your WEP or WPA key here. WEP offers 2 levels of encryption, 64/40 and 128 bit. I recommend using 128 bit as it is a stronger encryption. To automatically generate your key, enter a passphrase and click generate. If that option is not available, you can manually enter a WEP key in one of the fields labeled 1-4. If you use multiple, then select the one you want to use in the TX Key field. Once you have your settings entered, click Save.

Security of your wired or wireless router is extremely important. An unsecure router leaves your network open for anyone passing by to hop on and access your computer. You could even be providing free Internet access to your neighbor. The following are basic security precautions:

1. Change the default SSID
2. Make sure you change the default admin password. Use something unique. A combination of letters and numbers is best.
3. Change your SSID periodically.
4. Use the highest security algorithm possible. The best to use is WPA, but if your router does not offer that, use 128 bit WEP.
5. Change your WEP key periodically.

If at this point you cannot connect to the Internet, go back over the settings discussed above and ensure that they are set correctly. Also refer to the troubleshooting and FAQ sections of your manual for more information or to narrow down a problem. As a last resort, contact the manufacture of the router.. Most manufacuterer's are more than happy to help you with the settings.
