how do i get internet with no landline phone subscription. and no cable or satalite subscription,eg, sky, or Virgin media. can a "dongle" do this, if so what is it and how does it work
Well without telephone or cable infrastructure, you're basically left with WWAN aka Cellular internet. That is unless some other form of wireless ISP is available (like WiMAX)
Mostly WWAN is used on laptops by using a PC-Card or Express card device to provide a high bandwidth data channel over cell phone wireless infrastructure. There are routers that you can insert these WWAN cards into in order to share this cell internet connection with others on a LAN or to hook up a desktop
