Register Hardware takes a look at this Ethernet adaptor:

You can't beat a wireless network for true ad hoc connectivity. But like so many things in life, there's a catch - several, in fact. Depending on the construction of the building you inhabit, there may be areas where you can't get a signal. If, like me, you live in a neighbourhood stuffed with 802.11b and 802.11g networks, you can find them interfering with each other, limiting the available bandwidth. And then you've still got to ensure your WLAN's as safe as it can be from snoopers.
