You do not have to use the router provided by Race, though, we highly recommend it. When it comes to your router, you want to get what you pay for— especially if you have the "Gigafy Me" package (1000Mbps). Routers that provide a GIGABIT throughput speed can be pricey, with prices ranging from $200 all the way up to $1,000 depending on the make and model.
However, you are always welcome to do your research and purchase your own device. If you need some help or pointers on what to look for, take a look here:
With your monthly rental router fee Race provides technical support and managed WiFi capabilities, something that we cannot offer for other self-purchased devices.
It is important to note that if you are purchasing Race TV, you MUST use a Race router.
