Ruckus just announced the latest Ruckus Unleashed version of the firmware 200.8 will NO LONGER SUPPORT R310,R500, R600, T300, T300e, T301n, T301s Access Points.
So if you have any of these Wave 1 access points and you want to continue to use them, it appears that we are now stuck with the 200.7 version of the Unleashed Firmware forever.
I just setup a small home network using Unleashed Firmware and three rescued R500 Access Points and they work great Meshed together. I highly recommend this setup to all. It is unfortunate the Ruckus has abandoned future updates for all of these Wave 1 Devices. Hopefully they will reconsider this decision as it is a shame to condemn all of this great hardware to death. The good news is that the current Unleashed Firmware works great and if needed, it can also be flashed back to a Standalone device for use in simple home networks very easily.
