WAP 581 Slow download speed

[monconstruction]

Recently installed a new WAP 581.  When loading a video on wifi, I noticed it started to buffer.  I performed the same test on LAN, no issue. 

When I performed a speed test on LAN, 60+ mbps download. Wifi test was 4-5 mbps.   Upload on both are almost the same. 

I am not expecting it to be exact however, it's significant that you notice slowness.   Any ideas on what is causing this issue?  My wireless connection is 5ghz / ac.

Dear Customer,

How is your WAP581 connected to the rest of your network: switch, router etc.? What is your power source - PoE, power injector?

Are you using multiple VLANs?

There are many factors affecting the wireless throughput, so we are going to need more details in order to troubleshoot further. Please open a service request by choosing your local number here: https://www.cisco.com/c/en/us/support/web/tsd-cisco-small-business-support-center-contacts.html
