Yes, RCN does allow customers to use their own modem and router, provided that the equipment meets specific compatibility requirements set by the company. To ensure optimal performance and functionality, it is important for customers to select a modem or router that is certified for use with RCN's network. This certification often includes factors such as DOCSIS standards for cable modems, which should typically be DOCSIS 3.0 or higher. When using a personal modem, customers will also need to be prepared to configure the device correctly to work with RCN's services, which can include setting up the correct network settings and ensuring that any necessary credentials are input properly. For a complete list of compatible devices and additional information regarding required configurations, it may be helpful to refer to RCN's official website.
