The modems that we use are important. My current modem does not always play nice with the Republic Wireless service. I am thinking about upgrading, but I struggle to find good current information. This list Republic Wireless and Your Wi-Fi Router | Republic Wireless Wiki | Fandom powered by Wikia does not appear to have a single modem currently approved by Comcast, my current ISP. (Comcast is the only ISP on my street, so while they are not my favorite ISP, they do service my street on the edge of town.)
Buying a random modem does not appear to be a great answer - e.g. my current modem.
What do you suggest? What do I look for in a modem to work well with Republic Wireless? I currently have a Moto X Gen 2 phone if that matters.
