Testing 6.5.1-r11 on a XE3-4. However, one thing is still missing in the UI. I posted it here Enterprise Wi-Fi System Software Release - 6.5 - #8 by Space and the same issue in this version.
From my previous post:
I noticed that the options for “Minimum Unicast rate” and “Multicast data rate” is missing in Configure → Radio, when I login with Device setup (Local management). Reverting back to recommended version solves it. 6.4.2.1-r1.
So it seems like this is a v6.5 issue…
