   No.  The fiber comes into a box and the box also has the wifi router.   
   (I attached a second wifi router to give me better coverage, but that one   
   just operates in some "pass through" mode (if that is the correct term).)   
      
   According to things I've read on the internet, some people have bought   
   their own fiber hardware and then managed to do some end-run around the   
   security (and so on) that the phone company puts in place.  But I decided   
   that I wasn't going down that road.

   I could try turning off the DHCP server in the ISP's box.  However, they   
   have a habit of resetting and updating the software in their box, and I'm   
   not sure how long turning off that DHCP server would last.  I am not sure   
   what would happen when two DHCP servers are on the same LAN, but I imagine   
   Bad Things would happen.
