Connecting Wireless router to Cable Modem/Router

[WilliamP458]

My wife's sister has Comcast Cable. They installed a Modem/Router that the wireless part seems to have died. Can a wireless router be connected via ethernet cable to the cable modem/ router?

Yes, adding a wifi router to one of the ports will set it as a node on the dhcp server{modem} and if there is a conflict in ip address, usually will change it to a 10.0.0.1
