I have a R610, and I am trying to update the firmware. Normally this is very easy, just go to admin, the upgrade but it will not let me check the online or local buttons. I noticed it doesn't even show the firmware version.
I have tried resetting to factory and still same thing.
Find the desired firmware update from the ruckus downloads page for the r610. Download it to local machine. then login into the ruckus webgui from the same machine and you should have the option to browse to the local directory and then upload the firmware from there.
