Answers :

If you are having trouble connecting to a configuring your wireless router it is generally something simple. These are the most common reasons.
Is your computer WiFi enabled (does it have an adaptor)?
Is the login information entered correctly?
Are you using a firewall?
Are you using connection profile software (many times this is installed when you install a new adaptor)?
Are you adaptor drivers uptodate?
Is your operating system up todate?

More detailed troubleshooting steps:
Does your computer 'see' the network?
Does it see the signal? If it does are you pulling a valid IP address (192.168.X.X)? Also known as connected, no surf.
Check your Internet connection with a another computer.
Check for firewalls or security software.
Are parental controls turned on (controled through your browser or firewall)?
Check your browser.
Try to completely re-move and re-create the connection.

   Wireless Configuration for Windows XP

802.11b technology enables computers equipped with Wireless LAN cards to join a wireless network. Follow these steps to configure your PC with Windows XP to use its wireless card. You may use the links below to jump directly to a particular step in the setup process.
Verify that the Wireless hardware is working.
Verify that your Wireless card is registered with DHCP.
Configure TCP/IP to use your Wireless connection.
Configure your Wireless card to use the University Infrastructure.
Test your connection.

Verify that your Wireless card is registered with DHCP

Generally speaking, you will not need to register your card for DHCP. Instead, order for you to access the internet from your wireless card, you will first have to authenticate via a web page. This page will automatically launch if you have not authenticated. However, there may be some locations that still use the DHCP method for determining whether or not you are able to access the internet.

If you are not sure what areas are not configured for using the authentication method and which are not, you can register your card for DHCP service. It is free, and will not adversely effect other wireless services. There are online directions (http://www.umn.edu/adcs/network/dhcp.html) for registering your card with NTS. You will be asked to enter the MAC address for your card. Keep in mind that it takes 1-3 hours after you submit the form for the registration to take effect.

Configure TCP/IP to use your Wireless connection

The TCP/IP protocol is used to connect your computer to the Internet. The ethernet install instructions should have guided you through the installation and configuration of TCP/IP for your operating system. You may wish to refer to those instructions again. Make sure you set the card up to use DHCP.

Configure Wireless Card to use the University Infrastructure

Windows XP has changed much of how a connection is made. This is true whether it is a wireless connection or any other connection. This change has made it somewhat simpler to access the wireless network. However, for those unfamiliar with this new way of doing things, configuring the wireless card can be a bit troublesome. The first thing you will need to find is the "Properties" of your "Network Connections" The simplest way to get to this location is to right click on the "My Network Places" icon and select properties.



You may notice that there is an "X" next to your wireless connection. This is expected. It shows that your wireless card is properly installed, but you have not as yet connected to a wireless network. You need to right click on the wireless network icon, and select "View Available Wireless Networks"



You should see a list of available wireless networks. If you do not see "UofM Wireless" then you need to get into range of a University Wireless Access Point such as one by a kiosk.



In some instances, you may be using "Wire Equivalent Privacy" or WEP in some special cases. The University infrastructure does not implement WEP, thus you will be informed that the wireless connection is not secure. If you select "Allow me to connect..." you will then be connected to the University's wireless system.



It may do some things, but an icon in the lower right hand corner of your desktop should eventually appear stating that you are connected.



You are now ready to authenticate to the University's Wireless system. If you have set your connection up for DHCP, you should be able to browse the internet at any of the wireless area networks around campus.

Test your Wireless connection

To test the TCP/IP protocol, open your web browser (Internet Explorer or Netscape). You should see the wireless authentication page come up. If not, verify that your wireless card is working properly. (See the first step in this document).



NOTE: Even if you are planning on using another internet resource such as SSH or other service, you will still need to launch a web browser first and authenticate. After authentication, you will be able to access those other internet programs as you would normally.

If you have other Networking cards, you may want to remove them. The system will try to use all Network cards bound to TCP/IP. If a network card exists, but isn't attached to the network, it may try using that card to access the Internet.

You can type "ipconfig /Release" and "ipconfig /Renew" at a command window on Windows XP machines. This will attempt to communicate to the DHCP server. If an IP address is available, you will be assigned one quickly. If not, then the AP may be having problems, and you should try another location. If it works at another location, please contact the helpline about the problem. (612)301-HELP
