help for connecting multiple users to single internet connection

i live in ap and i am using excell media which is optic fibre internet connection.it was a single user internet connection with a static ip and mac locked that means it connects to only one computer.i have a netgear router. i want to share it over wii and laptop through wifi.it dosent have any login page like reliance.butit connects to the computer which mac address is registered.please help me sharing internet conneection

1. tell them to register yr router's MAC for yr acc
2. connect PC thru router and use whatever login method/app u use to login

router's generally have some login methods inbuilt... if u find yr login method there fine, else => point2

i mean my router has clone mac facility the problem arises when i connect through my router then only a local page of free movies of the isp can be opened and internet is not working
