@UTMorpheus I'll give it a shot but I'm pretty sure I was getting roughly the same speeds before turning QoS on.

Currently only getting about 30mbps download.... might just return this router...

If I test my internet speed from the LAN line from my modem I get the full 400mbps download I should be getting. If I run through the router at all (LAN or wireless) I get 140mbps down. Why is this...
