I’m often asked by people what the best wireless card for hacking is, especially if the card is something that can be used in their laptop. It used to be that you could only get an awesome card if you hunted down some expensive Orinoco PCMCIA card or bought one of the $200 PCAP cards. But, thanks to a company called Alfa, cheap cards with full “hacking” support are available.
The awesome part is you can get one from Amazon for $25: 1000mW 1W 802.11g/n High Gain USB Wireless G / N Long-Rang WiFi Network Adapter – Dongle
Specifically, the feature you are looking for with a good wireless card is one that can go into “Monitor” or “Promiscuous” mode. This is what lets the card sit back and report every packet it finds to the operating system. Most cards discard packets which are intended for other clients, unless a driver exists for it to prevent this, but that only happens if the hardware manufacturer releases their drivers open source.
Another awesome thing about this card is that it supports “Master” mode, which allows it to function as if it were a wireless Router. This happens to be the reason I bought the card, so that I can have an all in one home server / router solution.
For $25 you’d be crazy not to buy this thing! The one I got has an attractive semi-transparent base, blue LED, and some floral patterns on it. It comes with a small antenna, which gives it a farther range than an internal card and most other wireless cards. Also, the antenna port is standardized, so you could do something even cooler like plug in a cantenna for very far range. I was able to get the card working out of the box (no drivers needed) in monitor mode under both Linux and OS X, and I’m sure it will run under Windows with no issues as well.
