Fix: Gateway Authentication Failure Error U-Verse

The “Gateway Authentication Failure” error is sprung up while trying to connect to the internet with a U-Verse modem and it usually indicates an error with the configuration of settings. It might also occur due to the build-up of corrupt launch configurations by the router.

“Gateway Authentication Failure” Error

Certain launch configurations are piled up by the router to decrease the loading times taken by it to configure its settings. However, it can sometimes be corrupt and prevent you from being able to use the internet. Also, in some cases, the router configuration file can get corrupted due to sudden shutdown which can prevent it from connected to its servers.

1. Power Cycling the Router

It is possible that the error is displayed when the internet cache built up by the router is damaged and is preventing the user from establishing a secure connection with the servers. Therefore, in this step, we will be deleting that cache by completely power-cycling the internet router. For that:

  1. Unplug the internet router from the wall socket.
