Unknown computers attached...?

I give up. My PC-cillin firewall tells me every hour that there are about a
dozen unknown computers connected to my network. And this is after I took
the router off the line. All I have now is my computer connected to a cable
modem.

Are these 'unknown' computers those that are also using the cable-to-ISP
connection? Should I be concerned? If so, what should be done? If not, how
do I get the firewall to stop obsessing about those other computers?

Any suggestions?

First - unless you have a good reason - I would keep behind your router/NAT
device. Just that much protection is helpful.

Second - if your firewall is informing you and no one is breaking in - it's
doing its job.
If you don't want it to obsess - either configure it not to notify you so
readily or don't read the log file so often.

It seems to me it is doing what you told it to do. Keep people out and
notify/log attempts on your machine.
You might get less notifications behind a good NAT device/router... As it
will take the brunt of the hits - anyone getting through it will be more
dangerous and if your firewall reports on that - then you should probably
listen. heh
 
Thanks for the comments. I think your general 'drift' is really on target:
if it protects you it's a good thing, and I'll keep that in mind in using
the firewall for sure.

It turns out that I was maybe misleading as to what the firewall was
reporting. It actually captures data on 'wi-fi intrusions'. I guess such
an intrusion is potentially a bad thing, and the firewall does allow you to
'exclude' those computers.

What I still don't get is how my computer picks up such intrusions with me
not even having my wireless router in service. And as far as I know my
computer as no built-in wi-fi capability. (*Could* it have that anyway,
even though it's right now hard-wired to the ISP's cable modem?)

Anyway, thanks again for your reply.
