To access Wave Broadband internet service, you typically need both a modem and a router, although there are some variations depending on the specific setup you choose. The modem is responsible for connecting to the internet service provided by Wave, translating signals from the internet into a format that your devices can understand. A router, on the other hand, allows multiple devices to connect to the internet simultaneously, whether through wired connections or Wi-Fi. Some users opt for a combination device that integrates both functionalities, which can simplify the setup process. It is always advisable to check the service agreement or the specifications for the type of internet package you have chosen, as certain plans may include equipment rental options. For the most accurate and up-to-date information regarding equipment requirements, visiting Wave Broadband's official website would be beneficial.
