this is a wireless router by d-link:
i have this one installed at office and another wireless one at home.
how it works, we need computer geeks to explain here but i for one can say it is really useful. i use the internet from my laptop, my brother does from his mobile (set must be wifi enabled) and my niece uses here ipod kind of thing to access the internet too while mom uses the main computer it is basically connected to. at Rohail's they have three laptops and when i take mine even no one is disturbed. in other words, so many people using the same internet connection without waiting for turns. aur haan! you can also connect main computers through wires:
This is why i always buy the four port one because there are three proper computers here.
