sir,i m planning to go for bsnl broadband, now the problem arises that should i go for modem provided by the bsnl or shud i purchase it from market. if u suggest the bsnl modem then pls tell me the difference b\w type II and type IV , i think it is better to opt for type IV modem in the same price bcoz there is no difference in the price of type 2 nd type 4 nd type IV contains 4 ethernet port.
