hello everyone currently iam using bsnl internet which provides internet through telephone wire which is RJ11 and that we have to plug in my asdl router to use internet. but i want to switch to another isp but the problem is that this isp provides internet through RJ45 so can i use my older routher for the new isp which provides internet trough RJ45. i have seen lots of web sites saying that it is possible by disabling the dhcp and connecting to one of the lan ports.
