Comment (by hnyman):
Sounds normal. With a 100 Mbit/s internet connection, you are hitting the
performance limit of the router.
WNDR3700 & WNDR3800 are able to route some 80-100 Mbit/s traffic (down+up
together) depending a bit on the possible QoS system.
My own WNDR3800 results last year with a 100/15 Mbit/s wan connection:
I tested using netperf-wrapper with no shaping, with sqm-scripts and with
qos-scripts:
Nothing: 50 ms latency, about 98/11 Mb speed (ellipsis center).
SQM 100/11 Mb: 18 ms and 82/9 Mb speed.
QoS 100/11 Mb: 18 ms and 95/9 Mb speed
