Well, for some time some "data" has been "leaking" through my router
(supposed to have a firewall, which is confirmed by SOME tests), to my
computer, where my software firewall catches it.

I have been considering geting a 100 % stealth firewall/router. Including
port 0, that my Sitecom router won't let me make stealth anyway. It doesn't
have an official stealth option, you need to use a trick, but that doesn't
work for port 0. (Which can be detected).

Data passes through my modem to my router, and then to my pc.

Today, it just occurred to me: would having a stealth router make any sense
at all ? I really don't know how this works, but wouldn't scanners/computers
just detect my modem (brand Arris, got it from cable company), regardless of
what my router claims to be stealth ? My modem is directly connected to the
internet, and for as far as I know it doesn't have a firewall. So it's really
a technical question: can the mere presence of an active modem with an active
router be detected by others on the internet ? Imagine I got a 100 % stealth
router, wouldn't others on the internet detect me (IP address, basically
static computer name and IP), by detecting the modem ? And does it matter in
that case, whether my computer was ON or OFF ?

Insight appreciated.
