I have a wired ADSL2+ broadband modem+router. I currently use a USB cable to connect to internet using this modem. However I have wireless network card in my laptop. I want to use it so that I can eliminate the extra wire for connection. I want to know if there is any other device (like a wireless antenna) which I can connect to a port on my modem and then use the same wired-modem through wireless mode. I know the option of replacing the wired modem by wireless modem. However I need to check if I can retain my old wired modem and still connect to it wireless by introducing some intermediate device (e.g. some antenna etc).
