How to configure Buffalo Airstation with Alliance Broadband

I have a Buffalo wifi router:
Buffalo 150Mbps Wireless-N Wireless Entry Model Router - Buffalo:

Now, I'm taking Alliance Broadband connection. Can you please help me to configure the wifi router for the broadband connection.

Thanks in advance.


I've configued this and it takes 8-10 mins for configuring the router. But I've faced this problem. I'm trying to logout from PC and login to Alliance login page from my iPhone . I'm getting the username/password error. But when I login from PC, I can access the Alliance page from the iPhone . How do I login from the phone when the PC is turned off ??
