Wireless - Remove Cached Credentials

This article explains how to remove your cached CNetID and password for the wireless connection on a computer or mobile device.

The easiest way to remove your credentials from an authenticated device is to change your CNet password at http://cnet.uchicago.edu. Devices will not immediately be removed from the network, but will remain connected until the next time the client/supplicant authenticates, which may be up to 8 hours later. If there is a need to immediately remove a particular device from the network after having changed the password, follow the instructions below.
