Having the same issues as Noxious. And based on that I share his opinion. In this stage, not a real usefull device.
Used Mark IV firmware in the past (ported it to a cheap TP-Link router) and it worked then. Decided to buy the real stuf and not a single device gets associated.
I left it running for 24 hours in a very target rich environment. (at the office, with consent) I have hundreds of logfile entries saying it is 'trying to associate' but not a single one succesful.
If someone can get better results, please enlighten me!
