Suppose I have a desktop PC and several portable devices (a laptop, tablet, phone, etc.). I want the desktop to access the internet directly through an ethernet connection and then I want to wirelessly broadcast this signal to my other devices.
Basically, ethernet goes into desktop - and something sticks out from one of its USB ports that broadcasts a Wifi signal to all the other devices. Is such a 'something' available?
(A Wifi router would be the ideal solution if it weren't for the fact that I stubbornly want my desktop to be connected via ethernet and not wireless - also assume that the desktop has only one ethernet port.)
