Graduate House uses the same Wi-Fi as the rest of the University, so if you’ve accessed UofT Wi-Fi before your should already be set up to use it.
If not, while we can’t give detailed instructions for every type of device here, if you can access the web using cellular data or some other means such instructions are available for most popular devices at https://wireless.utoronto.ca/connect.
Failing that, the SSID (or network name) that you want to connect to is “UofT”. You’ll need to use WPA2 Enterprise security. Authentication (EAP) is PEAPv0, also known as PEAP with MSCHAPv2. Your login name will be your UTORid and your password will be your UTORid password. You may need to accept a certificate from “radius.wireless.utoronto.ca”.
