trying to download firmware for r750 so i can synch up with Ruckus One. 6.1 ...ximg file says it is 1.3 gb. i only get 50 kb. what is up with that?
.ximg files contain upgrades for SmartZone controllers. So no good for installing into an AP.
For your R750 to join Ruckus One, assuming you added the details in Wi-Fi > AP List > Add > AP, a factory reset with a paperclip might be enough to get it joined. Otherwise you can install Solo firmware: https://support.ruckuswireless.com/software/3853-ruckus-solo-access-point-118-2-0-0-875-release-r750
