Go back again & very carefully check your instructions for setting up your static ip. There's 2 steps to doing it. The 2nd step is the link (coloured brown) at the very bottom of the page called Configuring a Static IP Address. CLick on that link. I suspect you've missed that step.

I'm not sure why you'd put your ip address into your browser. You're not confusing with the modem address are you? You do know how to log into your modem don't you?
