> You would have to check with your ISP for supported modems.

   "CL Fiber internet" could mean more than one thing, including a
simple-looking Ethernet port, in which case, there would be no modem.
Or, it could mean some kind of DSL link to the premises.

   If all you need is a router, then an R6300v2 should work.  If you
need a modem, then you'd need a modem.  Ask CenturyLink what you need,
or what they'd like to sell/rent you.
