Setup new EAP670 in standalone mode, and was getting 450 Mbps download via 5GHz channel on a 1G WAN.

I then decided to try the Omada controller software, and adopted the EAP

I can now only get to 50 Mbps download. 

I turned down the gain on the 2.4Ghz channel, but no luck.

Anyone have suggestions?

Is the fact the settings are now controlled by the controller causing that much of a difference?

I am using a Synology router that is not part of the Controller.  I have a 605 v2 coming tomorrow, wondering if that will make a difference overall when it is adopted as the router?
