Wireless UWNet - 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.

4. If you are using Windows 8.1 or earlier and are still unable to connect, try the steps in this document: Windows - Quick Fix for Networking Problems. If you are using Windows 10, follow the steps in this document: [Link for document 70821 is unavailable at this time.].

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.

NOTE: This is a common issue with conference attendees and other university guests.

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

   • Windows - Displaying, Releasing and Renewing a DHCP Lease
   • Mac OS - Displaying, Releasing and Renewing a DHCP lease

7. If you are using a Windows computer, and are still unable to connect, try flushing DNS entries.

8. 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

• 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 - Connecting with the GlobalProtect (PaloAlto) 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.
