How to change IP Using Bell?

Well i want to change my IP back to a specific ip that i had before it changed because i am using a dynamic ip. I am using a router called SpeedStream 6520 and i cant seem to change it back to the ip that i want. It is a Dynamic ip so i know i can change it but how do i go about putting it to a specified ip?
Thanks

If you have dynamic IP, then change your IP address by following the steps:-1)Go to Start->Run->Cmd and Press Enter..Type in "ipconfig/release" for Current IP address and then type "ipconfig/renew" for New IP address.2)Either follow step 1 or Simply restart or unplug your modem/router .Doing either step 1 or 2 will change your Dynamic IP address. Visit Ip-details.com to check your IP address is changed or not


Note : to change a static ip is not an easy task . You need to contact your ISP and request them to provide new ip address. Until, you can't change it by your own . It is your public / external ip address . So, be aware with your ip and change it using your ISP's support .
