The sungem driver has nothing to do with your PC. It's for your iBook to
connect to an Ethernet cable.

The cable modem could still also be a wired router, or not, depending on
the model. Since you want wireless anyway, we'll assume that it doesn't
have router capabilities.

I'll assume that your old router is a model NWR04B. I recommend that you
connect its uplink port to the cable modem, and connect another one of its
ports to the PC. You can then leave the Base Station free for travel as
you prefer.

We'll cross that bridge when we get to it.

I've now lost count of how many machines you have.

It would make sense to put all of your wired equipment within reach of
each other.

Learn about the scp command.

Sounds like you want to share your entire home folder. Perfectly doable.

You mean you only create mail to send while you're ssh'ed into your ISP?

The router will be your primary firewall against net traffic. Whether you
want additional protection from intrusion into your wireless network
is up to you. This can be accomplished by placing a firewall between the
wireless router and all the wired machines.

That model is also known as M8209LL/A, Dual Ethernet, and "Snow." The
firmware for it is at:
