Hey, i recieved a netgear wireless router from a friend who had 2 and he gave me this for free, i wanted to use it to connect my upstairs computor wth my downstairs one wirelessly(nt sure if this is a word

) anywho i wanted to know how do i know whether the usb stick i have can do it or is it a specific usb stick that i need to plug in to connect and do they differ for each type of modem?
I have a bluetooth dongle as well and i wanted to know if this could be used a connector to connect to wireless internet?
1 last question if i do have a correct usb connector how do i set it up to connect with a modem in another room?
Thanks for any answers in advance.
