This guide will help you to setup your very own wireless network. It is intended to assist students living in off-campus housing with routers provided by Residence Life. Wireless routers should not be used on campus in the residence halls or Greek houses.

Cliff notes

  • Admin password = written on the bottom of your router, if you need to reset the router make this the admin password.
  • You ssid should be your apartment number.
  • Keep a post-it on the router with the SSID and password.
  • You will need to change the channel assigment from time to time if new routers are added by other tenants While you can select channels 1 through 11, channels 1, 6 and 11 are the only non-overlapping channels and should be the only channels used.
  • Whenever you unplug the ethernet cable from the cable modem power cycle the cable modem.

Models

The following Cisco/Linksys routers are distributed by Residence Life.

  • WRT54G V7.1
  • WRT54G V7.2
  • WRT54GS V2.0
  • WRT54G2 V2.0

Installation

1) What You Need

In setting up our network we will be dealing with 2 main devices. The cable modem which connects to the cable in your building, and the wireless router that broadcasts your wireless network.

The modem may look something like this:

Your router provided by Residence Life will probably look something like this:

2) Getting Connected

Please follow these steps:
1) Plug your cable modem into the cable outlet in the wall.
2) Attach an ethernet cable from the port in the modem into the "Internet" labeled port on the router.
3) Plug the power cords into both the modem and the router.

If you've done it correctly, it should look like this.

3) Prepare for Setup

Now that your modem and router are both connected and powered on, the router should have internet connectivity.

Now we need to attach the router to your computer. Take another ethernet cable and attach it from your computer's ethernet port to the number "1" labeled port on your router.
For clarity, I have removed the other wires to show you the proper connection below.

You are now ready to setup your wireless network. Proceed to the Setup section below.

Setup

0) Pre-Setup

Determine if you have the admin password for your router. Turn the router over and in black sharpie there should be an unique admin password for your router. Open a web browser to enter the URL http://192.168.1.1 At the login screen first try the password written on the bottom of your router. Try this with the username blank and the username as admin, if it works skip to Section 2 Wireless.

Next try the default admin passwords


Username:
Password: admin


Username: admin
Password: admin


Username: admin
Password: password


if it works skip to Section 2 Wireless.


Your router has been used by previous residents, you must follow this step before proceeding.


Restoring the Factory Defaults
This step will reset the default username and password on the router as well as any other settings added by the previous resident/user.
On the back of the router there is a RESET button. You may need a pen or something pointy to push the button. Hold the button in for 20 seconds, then release it (be sure to hold it in for the full 20 seconds).

Your router should now have its default username and password.

Please log in now to your routers and change the admin password to the one written on the bottom.

1) Login to Web Interface

In a web browser (Internet explorer, Firefox, etc.) enter the following URL: http://192.168.1.1

It should bring you to the following login prompt if you haven't logged in already. You must now enter the router's default username and password.

For the router models listed at the top of this page, the possible defaults are as follows:


Username:
Password: admin


Username: admin
Password: admin


Username: admin
Password: password


If none of these combinations work for you, please see Pre-Setup at the beginning of the Setup section of this page to restore your router to factory default settings.

2) Wireless

Once logged in you should see a page similar to this:

Select the wireless link marked above in red.

3) Manually Configure

As shown in red below, choose the option to manually configure your wireless network.

4) Name Your Network

Here we have the option to give your wireless network a name (SSID). This is the name you will see when you look for wireless networks to connect to on your computer. This should be set to your apartment number.

Enter your desired name and click Save Settings.

5) Network Security

Now that we've setup our very own wireless network, we have to make it safe. Choose the Wireless Security link shown in red below.

Now that we are on the security page, we must choose a security type to protect our traffic. WPA Personal or WPA2 Personal will provide needed security.

Choose a password for your wireless network like the example below. Please make sure that you let your roommates know that the password was changed. Put a Post-it on the router with the SSID and password so that your roommates know how to connect. Try to keep the SSID and password the same as last time unless you don't know what it was or you absolutely need to change it. Otherwise its just a hassle for your roommates.

Now once again, Save Settings.

You now have configured your router with a proper SSID (The wireless name) and a password.

Troubleshooting

If you are having a hard time keeping a wireless connection, this may be caused by wireless interference. Try changing the channel at which the wireless network broadcasts. This can be found on the Wireless page as seen at the beginning of step 4. It should look something like this:

The default Wireless Channel is 6. Try changing lower or higher to increase performance.
