I've never heard of a modem that has a built-in router but I think
Chris' diagnosis may well be correct. The modem certainly seems to be
acting as a router. Should that be the case and (for whatever reason)
you decide you'd like to keep 2 routers I'd suggest you google using 2
routers. You'll find lots of info on-line.
I recently had to do this. In my new house cable, internet and phone
enter the house in a junction box installed in the garage. It's
expected that most folks will use wireless throughout the house and only
run a single network cable to one room in the house. I wanted wired
connections in most places so I had 7 network cables running from the
garage to various rooms. Problem was there needed to be a router in
that garage junction box. I did that by installing an 8-port wired-only
router there (after a big argument with the cable company about who
owned the single AC power outlet inside their junction box). But I also
wanted wireless access for tablets and laptops so had to install a
second router in my office to provide the wi-fi.
I did just as I've advised and searched with Google how to use 2 routers
together. There are two methods. The simplest way (and what I chose)
is using the second router as a simple switch. Instead of running the
input line into the router's input port you plug it into one of the
outbound ports. Simple as that, the router operates as a simple switch
but with wireless capabilities.
The second method is to allow both routers to operate as routers which
has security advantages of creating a sort of firewall out of the second
router. I don't remember any of the details but if you Google it you'll
find plenty of references to tell you how to set it up. The only thing
I can recall is changing the IP address of (I think) the second router
to a value (I think) higher than the first router would assign. But pay
little attention to my ignorant ramblings other than to use Google to
help you out.

Many modern modems have a router built in, in which case you do not need a
separate one. The one I got from Comcast has built-in wifi and four ports
to plug in computers by ethernet cables. If your modem does not have a
built-in router, it¹ll only have one Œout¹ port, which you would wore to
your router.
