Bests & Worsts Reviews from Amazon

I carry a couple in my bag all the time now. Having been in IT for over 20 years I have come across several weird situations were a laptop/PC just doesn't like the WiFi radio it's connecting to. The most recent was a laptop that just wouldn't stay connected to brand new Cisco equipment. This laptop was literately within 25 ft of a new AP and would not stay connected no matter what I did. Add one of these little monsters, turn off the built in radio and problem solved.
