Hello everyone,

I'm scratching my head trying to understand this behavior. 

I have a 60Mbps connection into my house. All systems that are wired to the router (via switches) get the right speed; however, WiFi (as usual) is a different story. 

I expect WiFi to be slower, but when doing tests with speedtest.net or fast.com, I was getting about 15-20Mbps, not even 50% of what I should get. I used the 5GHz band and was standing next to the AP. 

Now, if I enable QoS on the AP, the speeds are what I expect (55+ Mbps). 

Why is it that with QoS enabled (which in my mind is adding some level of processing to each request) I get higher speeds than with QoS disabled (all other things being equal)?

Thanks in advance for your input!
