"Only in America :P - where else can you find a company that makes a buggy product and makes tons of money from it, have people exploit the heck out of it and then make tonnes MORE money from selling their existing customers "upgrades" that induce MORE bugs?" -markds
Can anyone confirm of the Alfa working for airpwn?
If you can't find what you are looking for, then you may want to do what I did.
I picked up a pack of 3 Linksys WUSB54G V.4 USB adapters from Ebay for about $20. They work great. The patched drivers are already in BT3.
Just make sure you get version 4, they have the ralink chips.
