A quick note to let you know that we have completed more testing in the BackTrack 4 pre-release final edition and are not going to advertise the n3 and RokN as BT4 compatible at this time. The devices are recognized on BT4 pre-release final, and can even detect networks in Wicd Network Manager, but cannot connect to them. We did no further testing on any of the apps, because we figured even if they worked with programs like Aircrack, we could not really say they work in BT4 if you can't use them for basic Internet access. However for people that just want to use the n3 for Aircrack or other apps, we may do some more testing in the coming weeks. Both adapters use a pretty highly recommended chip for Linux from Ralink, so we hope that these issues which appear to be driver related might be cleared up in the final release of BT4. For now, as 802.11n devices from other Linux-friendly chipset makers like Realtek are just coming to market in early August, we would say that using 802.11n in BT4 pre-release final might be a bit of a chore.
If you are looking for a device that will work great in BT4 pre-release final, we are launching later today in fact a new 802.11g adapter with RP-SMA connector called the RAID (stands for Rokland Auditing/Injection Device) that is very similar to the Alfa AWUS036S model. We will of course have a post on it when it is online and ready for purchase.
