200.5.10.0.291 doesn't fix the packet loss for stations connected to MAP

[dmitri_kalintse]

As described in a few replies to https://forums.ruckuswireless.com/ruckuswireless/topics/ruckus-unleashed-200-5-has-bug , I'm experiencing an issue with my Unleashed mesh set-up. The topology and set-up can't be simpler - one RAP, one MAP (both R710), one network (2.4+5), WPA2 auth.

Used to work flawlessly before upgrade to 200.5.x, with the same config.

After APs boot up, all starts off great. After a period of time (sometimes as short as an hour or so), stations connected to the MAP start experiencing packet loss / transmission delays. If MAP is power-cycled, problem clears - clients are happy, until they are not again.

When the issue is present, RAP-MAP speed test doesn't show up any significant slow-down - it's around 400-450Mbps, just as when all is OK.

Channels are stable - I don't see any movements, even after MAP reboot, it comes up to occupy the same channels as before. There is no significant interference. 2.4 uses Background Scanning, 5 uses ChannelFly.

Was hoping that upgrading to 200.5.10.0.291 would help, but no, it didn't.

Would really like my stability back, please.
