iBook loses cable connection

At times my iBook somehow gets knocked off line, in other words I lose
the connection with my cable isp, usually after using iTunes through a
firewire interface (a Motu 828 mkII), after unplugging the firewire
cable. I haven't figured out the exact sequence of events that bring
this on, but restarting the computer reconnects it and brings me back
online.

Anyone know what could be causing the disconnect, or perhaps an easier
way to reconnect besides restarting the computer?

Thanks,
Dave

iBook 600/10.3.3

Actually I just lost my connection again after the iBook woke from
sleep. This problem seems to have started or worsened after the 10.3.3
update...

Thanks again for any ideas.
