Arris TG862G
Disclaimer:
Due to the wide variety of devices available and potential variations in their firmware, the information presented below may or may not be accurate. For this same reason, OpenDNS support will generally not be able to provide device-specific assistance beyond what is provided below. If you need further assistance specific to your device, please contact either the manufacturer's support team, or your ISP if you are using leased equipment.
This combination router and modem is typically used as a bundled device with a service provider. Most, if not all, service providers use a custom firmware program that prevents users from changing the DNS server settings on the device. This is based off the support article below, which only provides steps for changing the DNS settings through your computer only.

What's the next step?
There are a few options to explore:
- Contact your service provider or Arris support to confirm if your specific device supports changes made to the DNS server settings. There's a possibility that your service provider may be able to release the device from its restrictions upon request.
- Your computers can be configured using the steps at https://support.opendns.com/forums/21618384-Computer-Configuration. This is as effective as using your router, but you'll need to set up your computer's manually with the above instruction set.
I still want to use a router.
This is one of the most requested options for configuring OpenDNS, because it can filter all computers and smart devices without modifying each setting individually. The alternative to the above options is to set up a second router to your network, and configure that device with our steps at https://support.opendns.com/categories/20080020-OpenDNS-Device-Configuration. This will act as the gateway for your home, and all the requested domains will be routed to OpenDNS.
RECOMMENDED: To make sure that the second router is the only device users can connect to, it's recommended to change the Arris's WiFi password and hide the WIFi name from being broadcasted. Unfortunately, the manual above only offers steps to log into the router's configuration page. You will need to look around the WiFi settings to change the WiFi's WPA password. We also recommend changing the admin password for the device, this usually can be found in the system settings. Please see the below screenshot where to find the WIreless settings and Utilities section.
