I am obviously not familiar with the ISP or hardware you are using, but
every dsl router/cable modem/switch that I've ever seen has 2-3
interfaces. One interface that connects to the ISP (they often call this
the WAN), one to the LAN (your local network), and optionally one to a
wireless network. If your computer has a 192.168.x.x address then that
was assigned by the router in your basement, not the ISP.
For the connection to the ISP, your router is a dhcp *client* (unless
you pay for a static IP). You should never mess with that interface or
you will spend many hours in customer service hell trying to repair your
For your LAN interface (and wireless interface if you have it) your
router is a dhcp *server* and your computers are the dhcp clients. These
interfaces are configurable by the end user (you) and can be changed to
*not* be a dhcp server, but to be a fixed IP gateway. You should also be
able to leave dhcp enabled and still assign fixed IP addresses to
certain hardware, but this depends on the router. In any case the ISP
router/modem/switch forwards the traffic from this connection through
the WAN interface to the ISP servers and the rest of the internet.
If you want to change the LAN settings on your router, you can usually
do this through an http connection on modern hardware. You should
connect to the router from a wired connection. Some hardware also allows
wireless connections to the administrative interface but this incredibly
insecure since anyone within range can re-program your network using the
default username/password combinition. Anyway, you usually use a web
browser and go to something like "http://www.routerlogin.net". The exact
site name, username, and password is often printed somewhere on the
router, or you can get your model number and do a search on the internet
for the manual which usually has this info.
It's just a network interface and it's not really any different from
configuring your PC interface. If you want to go this route I can offer
some advice, but you really need a copy of the manual on your desktop
before you start messing with this stuff. Especially since you've never
done it before.
