Brightspeed compatible modems
Which modems are certified by Brightspeed and which are recommended for the service's optimal performance are covered on this page.
Being aware of modem compatibility
Every modem is designed to operate in a given speed range and with a particular sort of internet technology. Depending on your location and the speed you chose, Brightspeed uses several core technologies (fiber and other DSL kinds).
Why is this important? Even if you have a Brightspeed modem, it won't function unless it can handle the particular speed and technology of your provider.
Recommended Brightspeed modems
A gateway from Brightspeed enables you to access the internet with WiFi-enabled devices without the need for additional hardware. The devices shown below are the newest WiFi gateways that we provide.
The appropriate gateway will be picked for you when you acquire internet service depending on the internet technology and speed available at your address.
Modem options

If you’re an internet-only customer, you may be able to order a new modem online.
Here's how to check: Sign in to My Brightspeed and find "Internet" under the Services tab. Then look for an "Upgrade Modem" link to go to online ordering. If you don't see the link, you can't order online at this time, but you may still be eligible for an upgrade. Call or chat and an agent will help walk you through the process.

Don't see your modem listed?
If your modem is not on the Brightspeed certified or recommended modem list, it’s either a retired Brightspeed device or what’s called a third-party modem (from another provider).
Utilizing one of our accredited or suggested WiFi modems (gateways), which have been examined and found to function best with our high-speed internet technology, is strongly advised by Brightspeed. Devices that are out of date or from a third party are more likely to have performance problems and may not connect properly to your internet service.
If you're ready for an upgrade, contact us to purchase or lease a new modem.
