Hi. We have two Ruckus AP's. A Zoneflex R300 and a R600 Access Point. They are being used without Zone Director at the moment. I have succesfully setup the R300 with the stand alone firmware. I am having a bit of trouble with the R600, the webpage with the downloads shows a whole lot of different versions of firmware. Which do I chose to get the R600 also to be able to standalone?
