Alfa 500mw usb wireless
I’ve seen some high powered wireless cards from Senao, but… 500mw I think is the most powerful wireless radio I’ve seen. This Alfa USB adapter appears to require 2 (!) USB ports for full power, but it can use just 1. It also appears that this is a USB wireless adapter compatible with linux (even some of the wireless scanning utilities on linux as well…)
Oh – and did I mention that it has a removable antenna?
