How to set MTU in UTStar 300R2U? I am having BSNL modem and those screens are not like MTNL 300R2U. After setting VPI and VCI it goes to another page where we can set Bridged, WINPPOE etc.,. Then goes to Service Name page and then it ends. There is no option to set MTU or TCPRWindow etc.,. Can some one help me? Settings in Windows registry is not getting effected.
