using WFfi as a wan with a cradle point MBR1400, how to bypass web authentication

Hi,

I am trying to use WiFi as a WAN with a Cradle Point MBR1400. Normally this is a non-issue. However, where I am currently located, one must first agree to terms and conditions of the free WiFi before you may use it. I can do this on a PC/laptop but can't figure out how to do it through the MBR1400. As a temporary solution, I am using my laptop to connect to the existing WiFi, use my web browser to click 'agree' to the terms and conditions, then share my WiFi to my laptop's Ethernet port. I then connect the laptop Ethernet port to the Cradle Point's WAN port. The Cradle Point LAN side then connects to all my users/printers/etc. It works, but there has to be better way. Suggestions?
