I recently relocated for new employment. I've been staying in an extended stay hotel for about 3 weeks now. The hotel I'm staying in gives its guests free Wifi access. However, it requires users to accept terms and conditions on a splash page via browser interface before they can use the network. This makes it difficult to use my Chromecast with the network, as it doesn't have a means of accessing that splash page. While I could call the IT help line, I decided to explore a work-around.
Like many networks, my hotel's network attempts to improve security by using MAC address filtering. Luckily, Mac OS X (10.4 - 10.10) makes it very easy to spoof your network card's MAC address.
Here's how to add a devices like Chromecast, AppleTV, Roku to a wireless network that requires a browser to authenticate and accept terms and conditions.
