This guide will cover how to reset the Arris TG862 router to factory defaults. It requires mentioning that resetting a device is not the same as rebooting a device. Rebooting is turning the device off and back on again to cycle the power. Resetting a device is typically referring to reverting all configurations or settings back to original factory defaults.
Warning: Resetting the router should only be done if you are out of other options. Consider the following before continuing.
The first step in any reset is to make sure the device remains on during the entire process. If the router gets turned off or unplugged during this process you could end up with a permanently damaged router.
Now you need to locate the very tiny reset button located on the back of the router. We have found it for you and circled it in red in the image below.
Now use a sharp object such as an unwound paperclip or tip of a pencil to press and hold the tiny reset button for about 10 seconds. If you don't hold the reset button down for the entire 10 seconds you may only reboot the router instead of the desired reset.
Remember that this will erase everything you have done to your router. Try other troubleshooting methods first.
Now that you have finished resetting the Arris TG862 router you should login to the Graphical User Interface using the default username and password from the factory. This can be found inside the user guide. We have found them for you and included them in the Arris TG862 Login Guide.
Next it's a good idea to change the router's default password to something new. This can be just about anything you like. This can be difficult so we have included a link with helpful hints on how to create a strong password.
Tip: After creating a password you should write it down on a post-it note and stick it to the bottom of the router for next time you need to login.
The last setting we urge you to change is the WiFi security. The security is reset as well as the password you use to secure your network. Some router manufacturers like to leave the security open as the default. We strongly recommend changing this to WPA2-PSK. If you need instructions on how to do this check out this How to Setup WiFi on the Arris TG862 guide.
