FortiAP U431F Slow Download Speed Issue

I have a number of FortiAP U431F AP's installed that have a download speed that is approximately %30 of the upload speed.  I have a 200Mbps connection which averages approximately 185Mbps upload and download speeds with wired connections.  Wireless connections average approximately 60Mbps upload and 170Mbps upload.

I have tried rebooting the AP's and making a number of configuration changes from the default profile to no avail.  Any assistance is appreciated.  Thanks in advance.
