Need separate router and modem (wireless) compatable with comcast or xfinity
I currently do not have ISP in my home. No router or modem either. I do have a smart phone (android) with unlimited data, but cannot cast to my TV using a Chromecast dongle I recieved as a gift. It appears I need at least a router to set a WIFI connection. It was suggested I get separate router and modem to avoid dumping the entire unit if one or the other fails, but was not sure about compatibility with Comcast. I prefer not to rent them. I understand the need forfuture proofing and would like some sound advise before making a purchase. Thanks in advance if you can help.
