Wireless UWNet - Unable to Connect

Wireless UWNet should work with most common configurations. This document contains some steps you can try to establish a connection if you are unable to connect.

In the event that you are unable to connect, there are a few things to check to attempt to determine the problem.

  1. First, try disconnecting from UWNet then reconnecting. See Wireless UWNet - Windows Configuration.

  2. Verify that the computer is configured to obtain an IP address and DNS server address automatically.

  3. Check to see if the computer is getting a valid wireless IP address. A valid wireless IP address should match the form 72.33.*.*. See below for instructions to verify this.

    NOTE: If the user has not yet registered, or they registered within the past 15 minutes, they may have a 10.136.*.* IP address. This will change to a 72.33.0.*, at which point they should be able to connect.

    • Click on the Start button. Vista Start Menu Icon

    • Type in Command.

    • Right click on Command Prompt.

    • Select Run as Administrator. A black window with white text should come up.

    • Look through the results for the header: Ethernet adapter Wireless Network Connection: (Windows Vista) or Wireless LAN adapter Wireless Network Connection: (Windows 7)

      ipconfig results. The header and IP address are highlighted.

    • Below the header, look for IP Address. The computer in the example above has the address 72.33.0.146. This is a valid UWNet IP address.

    • Navigate to the Start Menu.

    • Type in Command.

    • Right click on Command Prompt.

    • Select Run as Administrator. A black window with white text should come up.

  4. If you are using a windows computer, and are still unable to connect, try the steps in this document: Windows - Quick Fix for Networking Problems

  5. Check your web browser for proxies by following the steps in this document: Web Browsers - Checking for a Proxy. If there are any proxies enabled, disable them.
  6. NOTE: This is a common issue with conference attendees and other university guests.

  7. Release and renew the IP address using the following instructions:

  8. If you are using a Windows computer, and are still unable to connect, try flushing DNS entries.
  9. Disable any third-party firewall software (Norton Internet Security and Zone Alarm are two common examples) on your computer. These firewalls occasionally have an error that prevents internet connectivity, even if they appear to be configured to allow it.


If you are still unable to connect after going through the above steps, there are several things that could be the cause of the problem.

  • If your computer is properly configured, but you are not able to get a valid IP address, it may be the case that:

    • Another program on your computer is interfering with the connection. Please come to one of DoIT's Service Desks for further assistance. Service Desk Locations and Hours

    • UWNet is overloaded at the location you are attempting to connect. Each building supports a limited number of connections. When that limit is exceeded, further connections are not assigned an IP address. This is known to happen in College Library, Vilas Hall, and Grainger during peak hours. The only solution to this problem is to either wait for other computers to disconnect from the network, or move to a different building.

  • If you are getting a valid IP address, but are still unable to connect, it may be the case that:

    • Your computer is not redirecting to the wireless login page, or the login page is overloaded. This can be circumvented by connecting to the VPN Service if you have it installed already. Please see WiscVPN (Windows) - Connecting with the WiscVPN AnyConnect Client or WiscVPN (Mac) - Connecting with the WiscVPN AnyConnect Client for connection instructions. Ensure you use the WiscVPN-OnCampus profile.

    • There is a firewall, or some other software interfering with the connection. Sometimes, even if a firewall appears to be shut down or uninstalled, it will still interfere with connectivity. Ensure that any firewall software you have installed is turned off. If you are still unable to connect, please come to one of our Service Desks for further assistance.
