For the system to work properly.. the modem should be powered on and online
before the computer is booted.  The easiest way to accomplish this is to
leave it
on.  If the PC comes online before the modem is online the either the DHCP
request
or the ARP for your gateway address at boot will be unsuccessful and you
will not
be able to transmit or recieve.

Also the cable company monitors (or should) the signal quality for the cable
modem.
Leaving it on is good for you and for the others in your neighborhood.
Think of it as
a status monitoring device to help them keep the plant operating properly.
Everything
from transmit levels, corrected/uncorrected blocks power adjustments and
other
statistics can be polled from the modem.  Also if you do have issues with
your connection
they can see if your modem has been experiencing it in the past, if it is
cyclical occurring
at the same time each day and whether other modems in your neighborhood
exhibit the
same issues.

Depending on the cable company and the provider, these tools should be
available to the
engineering staff to monitor their network.
