Yes, Eth1 straight to the Switch, no issue. 825Mbps. We already opened a case with Ruckus.
We just downgraded to older version: R510_22.214.171.124.312.bl7
No, we are not using local IPERF3 server at all.
and wifi speedtest coming off of the Ruckus APs, doubled. However, AP-2-AP still hovering at 425Mbps.
The excercise of downgrading to an older fmw doubled our speedtest on WiFi, leads me to think this is a purely firmware issue.
