I spent some time this evening testing six USB wireless cards and want to share my results. I know I'm covering old ground with some of these but I've included relative signal strength in my data.
I guess I should describe my test set-up, while not scientific by any means, it is consistent. I used my POS internal Intel 4965/5xxx wireless card as the test AP in the aireplay-ng -9 -i <interface> <test interface> scenario. I started each interface in monitor mode on channel 9, which is the same channel my test AP, "pwn target biotch" is on. In each test, I measured the power reading for pwn test biotch and noted the results of the injection test suite. pwn target biotch was approximately 10 meters from my test location, on the other side of a wall.
The six USB cards I tested are as follows:
1) Alpha AWUS036H
2) Linksys WUSB54G
3) TP-Link TP-WN321G
4) EDiMAX EW-731USG
5) Hawking HWUG1
6) Alpha UBDo-G
A side note on the Alpha UBDo-G; this thing is a real beast! It's made for maritime use, is waterproof and has a mast antenna that is approximately 1.5 meters long. It's blasts! It's definitely not for wardriving, unless you're on a boat or in a 18 wheeler truck!
The results:

One note about the failed Attacks -5/-7 on all of the cards except the Alphas, the documentation from Aircrack-ng says that while these test attacks may fail in this scenario, it doesn't mean they will necessarily fail in real world situations. I'm going play around with the ones that failed Attacks -5/-7 in this test scenario to see if they do in fact succeed in full scale attacks.
Overall, my favorite is the Alpha AWUS036H because of it's performance and small size. I really like the Alpha UBDo-G because it really hauls a$$, but it's not very practical.



They don't support any o/s but windows, and were wrong about the chipset. Support told me the chipset was a ralink 2700, but when I entered the fcc id at
