Computer Sciences Wi-Fi Networks

The CSL maintains the department network used by all Instructional, Research, and Computer Science Infrastructure hosts. In addition, the lab also manages the department Wireless network to provide devices with 802.11 capabilities access to department and Internet network resources.

Wi-Fi Network

The CSL Wireless Network is designed to allow users access to Computer Science network resources as well as the Internet from any device with an 802.11 wireless network card. Per University policy and to maintain a secure network, authentication is required to access wireless services. Once authenticated, some CSL network services (such as printing) are provided via transparent proxies for convenience.

Network Names (SSIDs)

For a step by step connection guide, please see: How to connect to COMPSCI.

For more information on these networks, see the detailed descriptions below.

There are three WiFi SSID's available within the department - COMPSCI, which is WPA2-enterprise secured, and COMPSCI-OPEN, which has no encryption and uses a web form for authentication. Both networks support 802.11 a/b/g/n on both the 2.4GHz and 5GHz spectrum. The third Wi-fi SSID available in the CS building (and across campus) is eduroam.

COMPSCI and COMPSCI-5GHZ

COMPSCI is authenticated with 802.1x, which is supported by all modern operating systems, wireless cards, and handheld devices. Using 802.1x will keep your network connection encrypted and save you from entering your password in a web form when you connect. In order to use 802.1x your CS password needs to have been updated since the beginning of 2011. For details and instructions to set up 802.1x authentication, see the CSL 802.1x Documentation . COMPSCI-5GHZ is accessible if your wireless card is capable of 5ghz, we recommend connecting to this band if your computer or device can support it.

COMPSCI-OPEN

COMPSCI-OPEN is an unencrypted wireless network intended for devices which do not support 802.1x. After connecting, open a web browser and you will be redirected to the authentication gateway to log in. Please use a VPN service such as the CS Department VPN to keep your wireless connection secure.

eduroam

eduroam (education roaming) is a secure worldwide federated network access service developed for the international research and education community. UW-Madison is member of eduroam, so you can use your NetID credentials (not CS login) at any eduroam-enabled school and get instant network connectivity. This also means visitors from participating schools can get network connectivity at UW-Madison. For more information about eduroam, reference the Accessing eduroam documentation. For access to CSL services, a VPN is required if using eduroam.

Printing from the Wireless Network

A user of the CSL Wireless Network can print to CSL printers after they are authenticated. The authentication gateway will add your user identification information to printing requests. Your quota will be charged for pages printed.

To print to a CSL printer, please see the instructions for your OS:
