I once bought a Hawking usb wifi adapter and a Hawking 2 watt amplifier. With the amp my configuration utility showed a lot higher db's, but I was able to connect farther and browse faster WITHOUT the amplifier. Has anyone had any luck with some brand or another? I'd like to know what I buy has worked well for somebody...
