Unifi USG & QoS

Using version 6.045 on my controller. with a USG (not the pro). My internet connection is 200 mbps download and 5 mbps upload. When I enable QoS, my network download speed slows to a little less than 80 mbps (which I’ve read will happen with the USG). When I turn QoS off, my speed jumps back up to 200 mbps, however, I my work VPN will not authenticate, nor will my Teams or OneDrive work. Turn QoS on, everything works fine. Are there some other setting I need to look at when turning QoS off that will allow my VPN to authenticate ?



We don’t use any UniFi routing equipment anymore. Just their access points and switches. Their forums might be more helpful.
