Dear All! Many thanks for everyone for the suggestion. Special thanks to redstone and bhole_babaji for sharing your indepth idea for me. I think, I do need a wireless card, since my laptop is not equipped with any wireless processor or centrino. Moreover, like you said, the invasion of my privacy by intruders, is good to know. Also thanks to no_way and AX- sometimes, in life, making stone soup makes hell lotsa sense. Good to know that people are stupid, but they are not that stupid either. Once in a while, we need an endorsement for ourselves right, just seeing how nonsense others are??? By the way, no offense hai.... Pheri-Vaytaula VR
