The instructions below reference the VTC WiFi network, but the instructions are the same for each institution (CCV, NVU, Castleton, and VTC). The screenshots used are from Windows 10, so if you have a different version of Windows the screenshots may not match up, but the process itself is the same.
Start by clicking the wireless icon in the lower right corner (next to the time), then select the campus-specific WiFi network. Make sure the check the “connect automatically” box, then click Connect.

You will then be prompted to log in. Enter your username (abc01010) and your password and click Connect. You may be prompted again to ensure you want to connect to this network, say yes/connect to each prompt.
