These PCs are not wifi capable.  There are many on Amazon / ebay and they seem to be all duds, with included Wifi Dongles.  The dongles themselves do not work well, and you will not get a quality internet bandwidth in comparison to any integrated chipset. I feel like teh advertiser intentionally obmits this in the add - on teh hope that you will not return the item after recieving it.  Really poor business practise.  Why not skip the low grade wires mouse and keyboard and install the intell chip, they're $30.
