A Chromebook C720 using a USB3-to-GigE adapter tests to about 500 Mbps
with iperf.

$ iperf -c istar

Client connecting to istar, TCP port 5001

[  3] local 172.22.22.11 port 44658 connected with 172.22.22.20 port 5001

Not an extensive test, but going to other machines on the network showed
similar results from the C720.  Those other machines test in the 940+
Mbps between each other.  As a gige router, not good enough, but as a
WAN gateway - probably fine for most of us who will never see GigE
connections.

Is anyone here signed up for the 2Gbps service from Comcsst at home for
$300/month + $500 install + $500 "activation" + $??? equipment fees?
Comcast claims 1.5M people in the Atlanta area can get this service.
