First, delete all cookies. Next, go into whatever software manages your WiFi connection and delete the Courtyard's Internet connection. Reopen your browser and it will connect from scratch, giving you the option of selecting a different connection.

I'm on my Mac right now. To do it on this computer, I would select the WiFi icon on the top right of the screen, choose "Open Network Preferences" and "Advanced." Locate the Courtyard on the list - it will likely be last if you haven't connected to the CY Internet before - and click your delete key. Close the open windows and start your browser.

My PC has software which manages my Internet connections, which can be accessed in the right side of the tray at the bottom of the screen. It's a similar process, where you find the list of networks and delete the CY from the list.

Hope that helps. Sorry I cannot be more specific without looking at the PC.
