What is the hardware called that allows you to scan wifi connections?

Hi,

My old mobo had a small attachment with a small antenna (?) that showed me the wifi networks around me. What are these called? And are there ones that can scan very large distances/ranges?



Thanks.

Sounds like any old wifi adapter. You can get them in USB sticks, cards ,etc.
