A friend is getting a new BSNL connection and he has been asked to either buy one from BSNL (Terracom) wi-fi modem . The people at BSNL have no clue except some details like it supports 30m and 2.5 Mhz. On the other side, he has been told, if he is interested he can get buy a Belkin n-300 from outside.Any suggestions on what he needs to do.
