said by Youkalikat :I must have a hybrid modem/router from Verizon
VZ at one time used the Westell 9100VM which is a combined VDSL2 modem and router for MDU installations. If you live in an MDU and have the Westell 9100VM, then yes, you have a combined modem and router.
If you have an Actiontec router or the Westell 9100EM you have a MOCA capable router, not a modem/router combination. Just because it connects to the coax dors NOT make it a modem. People forget that the original 10BASE5 ethernet networks were RG8 coax.
