Activating the Arris SBG7580-AC SURFboard Modem & Router

So you got your SBG7580-AC modem and router in the mail, or bought one online or in-store. Now to set up the hardware and activate it. Watch the video below from Arris to get connected.

Video transcript: Hi. I’m Tom and I’m going to show you how simple it is to set up your new SURFboard cable modem and WiFi router. This video will feature the SBG7580-AC but setup is similar for all of the SURFboard models listed here, with some slight variations on some older models.

Always be sure to check the quick start guide included in the box for specifics on connections and LED indicators.

First, let’s review the contents of the box. It should contain the following, this SURFboard cable modem and WiFi router, the power supply, Ethernet cable and the quick start guide.

Now let’s set up your device. Make sure you have subscribed to a high speed internet service from your cable provider and that there is a live coax connection in your home. From that location, connect one end of a coax cable to a live cable outlet. Keep in mind the coax cable is not included. Connect the other end of the coax cable to your modem and hand-tighten the connections. Using the included Ethernet cable, connect it to one of the Ethernet ports on the back of the device.

This will allow you to confirm connectivity once setup is complete. Now connect the power supply to your WiFi modem and connect it to a power outlet.

The LEDs will illuminate indicating power, downstream and upstream connectivity, internet connectivity, 2.4 gigahertz WiFi band and 5 gigahertz WiFi band if it’s available on that model.

There are two ways to activate your device. You may call your cable operator or you may try to self-activate. If you’re comfortable with the process, we recommend you try to activate the device yourself via a web browser.

Once connected to your WiFi modem via Ethernet or WiFi, simply open up a web browser and you will be redirected to your service provider self-activation page. You will be instructed on how to complete the activation process for your device on the service provider’s network.

If you are not redirected to the activation page or if the internet connectivity LED is not illuminated, you will need to contact your service provider for assistance. Be ready to provide the model number, the HFC MAC ID and the serial number located on the white sticker on the bottom of the device.

With the computer or mobile device you used to activate the modem, browse to www.surfboard.com to confirm you have internet connectivity.
