No, a modem is not required to use our internet service. In fact, it may (in some cases) hinder your ability to connect to the internet as some combination modem/routers are not supported by the technology that Arvig MultiWav uses.
If you own an existing modem/router combination, you may attempt to use it with Arvig MultiWav, however please be aware that you may need to purchase a new router to be compatible with our service.
