Go back to dslreports.com and run the MTU test and change the notebook
parameters with Dr. TCP. Also, when doing the test on the
directly-connected notebook, reboot the modem before testing.

Rebootig both modem and router are the first troubleshooting steps for
diagnosing a connection issue on broadband cable.

You are aware that cable internet is shared? If one computer on the
network is downloading on a 3Mbit/s connection at 2Mb/s, the other
computer has essentially less then 1Mbit/s bandwidth available. If the
first computer is using P2P file sharing, the total bandwidth can be
consummed by the first computer with any significant upload rate. At
2Mb/s download, and say 180Kb/s simultaneous upload, the will be almost
no bandwidth available for the second computer.
