GetUSB.info featured a high powered wireless USB 2.0 adapter from TRENDnet. The Geeks plan to run this as a Gizmo of the Day in the future when it becomes more available.
TRENDnet has a high powered wireless USB 2.0 adaptor at 108Mbps, the TEW-445UB. This means greater range for wireless devices from the main hub, about 300 feet indoors and up-to 900 feet outdoors! Not bad, but be sure to use either the WEP or WPA encryption technology otherwise your entire neighborhood will be piggy-backing.
This little gizmo will set you back only $70USD and would be appreciated by any well-connected geek!
