I use my bsnl broadband 256 kbps using LAN connection, and found it was not up to the speed of 256, which it should be. One of my friend told me that if you use it through through USB port, the speed will be improved. Actually, they gave both option to use, but the guy that installed it chose LAN rather than USB.Now my doubt is whether is it true that if you connect the modem through USB port, will the speed be increased or both are same??
