Wireless FAQ for Windows XP

I am connected but none of my programs seem to be able to access the internet.

In order to complete the connection process you must open a web browser. The browser will then be automatically redirected to NMT's wireless login page. Enter your Banner ID and password to finish the connection process.

How do I see what wireless channels are available?

  1. Under Windows XP if the wireless networking card is enabled, Windows will scan the area looking for wireless networks. When Windows finds a network that it can connect to, a message box will be displayed.

  2. Click on the message box and a new window will appear.

             From this window you can pick one of the wireless networks to connect to and use.

What wireless channels can be used to connect ?

In the wireless setup there are two different channels that can be used:


How do I log into the unencrypted channel?

The NMT-UNENCRYPTED-WEB-LOGIN is an unencrypted channel which will work with just about any client computer and operating system combination. This channel should be used with caution because anyone could monitor what you view and do over that channel if isn't specifically encrypted between the client computer and the server (i.e., https, ssh).

  1. To login and use the NMT-UNENCRYPTED-WEB-LOGIN you just have to open a web browser and wait for the login page to load. The login page currently looks like this:

The username is your Banner ID and the password is the same password you use to access Banweb. The web login page is encrypted via SSL which will prevent people from being able to steal the passwords used in the login process.

How do I connect to the encrypted channel?
The NMT-ENCRYPTED-WPA-WPA2* is considerably more secure than the unencrypted channel, but is much more complicated. Currently it supports several different modes of operation. The table below is a summary of the different modes available.

Encryption     Authentication System    Tunneled Authentication

WPA-AES           PEAP                                   MS-CHAPv2
WPA-TKIP          PEAP                                   MS-CHAPv2
WPA-AES           EAP-TTLS                           PAP
WPA-TKIP          EAP-TTLS                           PAP

WPA2-AES         PEAP                                   MS-CHAPv2
WPA2-TKIP        PEAP                                   MS-CHAPv2
WPA2-AES         EAP-TTLS                           PAP
WPA2-TKIP        EAP-TTLS                           PAP

*WPA2 can only be used if you network card supports it.
**Note: If you plan to use EAP-TTLS please download and install SecureW2 client.

What encryption modes are available?

  1. Open the "View available wireless networks" window. Select NMT-ENCRYPTED-WPA-WPA2 and click connect.

  2. After the Connecting window has closed, a message should appear by the task bar that says "Windows was unable to find a certificate to log you on to the network NMT-ENCRYPTED-WPA-WPA2"
  3. Close the "View Wireless Networks" window.
  4. Click properties on the wireless network card that is being used to make the connection and select the wireless networks tab.

  5. On that tab, click on the properties for the preferred network NMT-ENCRYPTED-WPA-WPA2.
  6. A new dialog will open and in this new dialog select the appropriate Network Authentication type and Data encryption:

How do I switch to using the built in windows wireless utility?

If  you would like to switch from using the card manager utilities that came with your wireless card to the built in Windows utilities, change this by performing the following steps:

  1. Click on the My Computer icon on the desktop.
  2. Now click the right mouse button (or left mouse button for left handed mice) and a menu should appear.
  3. Click on the Manage item in the menu. A new window will appear. In this window on the left hand side select "Services and Applications" and the submenu Services. On the right hand side scroll down and find the item named "Wireless Zero Configuration" as pictured:

  4. Double click on the "Wireless Zero Configuration" item and a new window will open.

    Make sure the settings for startup match what is shown below:

  5. Now click on the "My Network Places" icon on the desktop and click the right mouse button (or left mouse button for a left handed mouse) and a menu should appear.
  6. Click on properties and a new window will open up. Now select the wireless network connection and click the right mouse button (or left mouse button for left handed mice) and a menu should appear.
  7. Click on the properties item and a new window will open up. On this new window click on the "Wireless Networks" tab and make sure the check box at the top is clicked as shown below:

What authentication system is directly built into windows?


What authentication systems can be used in Windows?

PEAP with MS-CHAPv2 is built directly into Windows. To support EAP-TTLS windows will need additional software and we have found that SecureW2 (located at: http://www.securew2.com/uk/) is a good client.

Troubleshooting the wireless connection

In a weak signal area, the authentication system seems to stall and when you move to a place with better signal it still will not let you in.

This problem is caused by stale session that has not been cleared on the wireless system. When you move to the new location the wireless system still sees the old session and it won't authenticate until the old session has been cleared. To clear the old session you can disable the wireless network interface for ten minutes and then try again.

After disabling the wireless network interface to clear out a stale session and trying again, it still doesn't work.

This problem is caused by your drivers not actually turning the radio of the wireless network card off. Try turning the computer off for ten minutes and then try again.

It is hard to connect to any of the wireless system even when you  have good signal quality.

This problems to seems to be most often associated with older drivers. Get the latest drivers that are available for your wireless card. Make sure that you are using Windows XP SP1 with http://support.microsoft.com/?kbid=815485 patch applied or Windows XP SP2 http://support.microsoft.com/?id=893357 patch applied if you are trying to use the encrypted networks. Double check the driver options of your network card and verify that it is set to auto for any properties that can do auto.

When using the encrypted network, it seems to take a long time to process the authentication before logging onto the network.

This is not exactly a problem. This slow authentication is caused by the wireless system negotiating an encryption key when you first access the system. If windows has not been rebooted after such a negotiation, the authentication will be faster.

You just changed your banner password and the new password doesn't work.

The wireless runs updates to get the new password information on a regular schedule, but it isn't instantaneous, try logging in again in about 15 minutes.

Your wireless card says that it supports WPA2 but you cannot select that for an authentication type.

Make sure that you have Windows XP SP2 because WPA2 only works with Windows XP SP2 and you must install this http://support.microsoft.com/?id=893357 to get it to be available. Also make sure that you have the most recent version of your network drivers installed.
