Hi John,
1. Find out your Brennan's IP address. It appears onscreen in the scrolling information - mine is 192.168.1.2 to give you an idea of what to look out for.
2. Turn on wi-fi on your Samsung (I'm assuming it connects to the same router as your Brennan) and type that address into the browser as though it were a website.
3. Done! You're on the web interface for the Brennan. It's controlled via touchscreen.
hope this helps,
mil
