Yeah I prefer to have low latency rather than raw bandwidth = especially since I am a gamer and my family likes to be on YouTube and down= load files and be on the Internet in general.=A0 So the low latency is a bi= g plus in my book.

At 60Mbit down you are unfortunately hard up against the limit of what
the SQM system can do on the wndr3800 without running out of cpu. What
is your SQM set to?

So long as you care more about low latency rather than raw bandwidth,
you are in good shape with the sqm system, it seems.
