Rate Limit (5Mbps) appears in effect when AP's are set to unlimited (user / ssid)
Worked with consultant and confirmed no rate limits set on vlan hosting the route out for Guest WiFi. Speedtests will initially jump (Download) to 30 Mbps on start up then quickly come down and sit at 5Mbps. (Upload) Tests gradually climb to 5 Mbps and stay there. Not sure where this is being set, but the AP's are set to unlimited.
