eduroam - Accessing and Logging in to eduroam

eduroam, UW–Madison’s secure wireless network, is updating its trusted certificate on Tuesday, April 23, at 10pm. You will be prompted to accept/“trust” the new certificate on each device that connects to eduroam. Please accept this new certificate, as a valid certificate guarantees that the network you’re connecting to is legitimate. If you do not accept, you will not be able to connect to eduroam.

This document gives UW-Madison NetID users a brief description of eduroam and a link to the eduroam Configuration Assistant Tool (CAT).

UW-Madison is member of eduroam, so you can use your NetID credentials at any eduroam-enabled school and get instant network connectivity. This also means visitors from participating schools can get wireless network connectivity at UW-Madison, and UW-Madison users can use it at other eduroam institutions.
