I came across a good post here: https://forums.ruckuswireless.com/ruckuswireless/topics/best_practice_optimization_by_cli_for_zone_director that goes over some CLI configuration changes to optimize your Ruckus setup. Personally, I changed the bss-minrate and have seen better roaming behavior:
- SSH into your ZoneDirector
- Verify your current WLAN settings with > show wlan name “wlan name”
- Enter config mode with > config
- Enter WLAN configuration wtih # wlan “wlan name”
- Change the bss-minrate with # bss-minrate 5.5
- Then exit and the changes are saved
