How do I get wireless access on campus?

-For Windows XP

Connecting a Windows computer to the new SFA-LAWN.

Changes in SFA-LAWN Configuration Effective August 23, 2006

Beginning on Wednesday, August 23, 2006, SFA-LAWN will provide an encrypted connection for you and will require that you authenticate (log in) each time you connect to the wireless network. These enhancements will require that you make a “one time” change to the connection settings that you have previously been using on your PC.

Once you have completed this process and start to use SFA-LAWN, you will have to go through the NetReg process. This applies to everyone...Faculty...Staff...and Students. As always, the NetReg process must be completed at the beginning of each semester.

Before beginning, please note the following:
Do not use a wireless connection at the same time you are using a wired connection. This can cause some serious problems. using your wireless connection and then decide to use the faster wired connection, please right click the icon under Network Connections and then click disable. For security and operational reasons, please disable your wireless connection when you specifically using it. By nature, wireless connections are not as fast as wired connections. So, if you have a choice, a wired connection will give results.

To enable your computer to be connected to SFA-LAWN:
Click Control Panel
Switch to Category View, if not already there

Click "Network and Internet Connections"

Network and Internet Connections
Click "Network Connections"

network connections
Right-click your wireless connection and click "Properties"

If the wireless connection is not ENABLED you will not see the "Wireless Networks" tab below. Enable the connection before doing the Right-Click.
Use the scroll bar and scroll down to the bottom

Double-click "Internet Protocol (TCP/IP)"

Select "Obtain an IP Address Automatically"
Select "Obtain DNS Server Address Automatically"

Click "OK"

Select "Wireless Networks" tab

You should get…

Make sure the "Use Windows to configure my wireless network settings" box is checked off

Click the "Add" button

On the next screen...

For "Network name (SSID)" enter "SFA-LAWN" CASE Sensitive
For "Network Authentication", use the drop-down selection and choose "WPA-2" if available, otherwise"WPA"
For "Data encryption", use the drop-down selection to choose "AES" or "TKIP"; "AES" is preferred
The other options should then 'gray' out and no longer be selectable.
Your screen should look like...

If you do not see "WPA" under the Network Authentication, read the info about the WPA Update

Click the "Authentication" tab.
You should get…

Make sure the "Enable IEEE 802.1x authenticaion for this network" is checked off
For "EAP type", use the drop-down selection to choose "Protected EAP (PEAP)"
Make sure "Authenticate as computer when computer information is available" is NOT checked off

Click the "Properties" button
You should get...

Uncheck "Validate server certificate"
For "Select Authentication Method:", use the drop-down selection to choose "Secured password (EAP-MSCHAP v2)"
"Enable Fast Reconnect" will work either way.
Click the "Configure" button

You should get...

Uncheck "Automatically use my Windows logon name and password (and domain if any)"
Click "OK" . If you do not uncheck this box the laptop will send whatever name you have given your laptop to be
authenticated instead of your mySFA or Guest ID that you need to use.

Click "OK" until all boxes are closed.
You may have to restart your system.

You should get this at the bottom, right side of your screen...

Security Notice...
The danger in using Ad-Hoc Networks

1. Click on the Wireless option in the System Tray and open the Wireless Network Connection window.
2. Click on "Change advanced settings".
3. In the Wireless Network Connection Properties window, click on the Wireless Networks tab.
4. Click on the Advanced button.
5. Click on "Access point (infrastructure) networks only" This workaround prevents you from connecting to any ad-hoc network in the first place.

...and this box should pop-up

Fill in the fields as shown.
Click the "OK" button

The NetReg Process:
The NetReg process simply matches your mySFA info to your network card's serial number (MAC address). That way, if your computer gets infected and we have to block you from our network, we can look up your MAC address and cross reference that to your name. This makes the entire resolution process go more quickly for everyone and a lot smoother for you.
When you first open a browser, you will be re-directed to our NetReg page. Read the info and click the "Next" button. On the following screen, enter your mySFA name and PIN in the boxes and click the "Accept" button. You should then get a message indicating a successful registration. If not, write down the error message info and call the SHACK at x1212 (Faculty/Staff) or x4357 (Students).
If you were successful, reboot your computer. Everything should work, now.

-For Windows Vista

Windows Vista Wireless Connection Settings for the SFA-LAWN

Microsoft Compatibility Notice
Due to a known issue with Microsoft Windows Vista, many computers running Vista are unable to establish an initial connection to the SFA Wireless Network. This is the result of using Wi-Fi Protected Access (WPA) in conjunction with Advanced Encryption Standard (AES) - as required by The State of Texas. Microsoft and Stephen F. Austin State University are aware of this issue and Microsoft is working to resolve the issue. Until then, no Windows Vista machine can be guaranteed to connect to the SFA-LAWN. For further information, reference Microsoft Knowledge Base Article #935222.

The SHACK will configure any Vista computer to communicate with the SFA-LAWN. The SHACK can also install a hotfix from Microsoft to help resolve this issue. However, this hotfix has not been released to the general public and has not undergone full regression testing. As a result, Microsoft cannot guarantee that this hotfix will not create other as-yet undiscovered issues.

Once a computer has been properly configured to connect to the SFA network, the system will detect the network and start prompting the user for additional information (The user's mySFA username and PIN). At this point, the behavior of the system becomes erratic. Some systems will connect immediately while other will continue to prompt the user for a mySFA username and PIN. Some systems have connected after a few minutes, while others have connected after over an an hour of continued username and password entry. Some computers have simply not connected at all.

For further information on this issue, contact The SHACK at (936) 468-4357.
