I have 1 desktop and I connect to internet using a wired ADSL Modem.I would like to use this connection on my mobile phones via WiFi now. As far as I understand there are 2 options:1. Buy a WiFi adapter [usb/card] and use a software like Virtual Router Manager.2. Buy a WiFi router.Can you please elaborate on which option would be better (or if any other option would be better) and what each option would cost?
