The “gateway authentication failure” error is come up while trying to connect to the internet with a U-verse modem, and it often detects an error with the settings. It might also occur because of the build-up of corrupt launch configurations by the router. The router gathers up particular launch configurations to decrease the loading times taken to configure the settings. But, it can sometimes be corrupt and stop you from using the internet. Also, in some cases, the router configuration file can get corrupted because of the sudden shutdown, preventing it from connecting to the servers.
How To Fix Gateway Authentication Failure?
You can try the below methods and fix the issue. Follow the steps, and you will know how to resolve the problem.
Power Cycling The Router
The error may show up when the router's internet cache is damaged and stops the user from making a secure connection with the servers. Thus, in this step, we will be deleting that cache by entirely power-cycling the internet router. Follow the steps:
- Unplug the internet router from the wall socket. Then press and hold the power button given on the back of the router for at least 15 secs.
- Later plug back in and press the power button to turn it on. You need to wait for the internet access to be granted and then check to see if the issue exists.
Reset The Modem
If that did not work out for you, we could try to reset the current modem configurations. You can use the reset button on the back of the modem. You can also do this through the router’s settings page. We have given both the methods below:
Reset through browser: You can open the browser and then type 192.168.1.254 in the search bar. Then you have to press enter and log in with the credentials. Then you have to click on settings and select diagnostics, and click on the reset option. You select the reset to factory default state and then wait for the webpage to proceed with the action. Once the router has been reset, wait for it to configure itself and later check to see if the issue exists.
Reset Through Router: You need to get a hold of the small pin and then navigate to the back of the router. Later, insert the pin inside the small reset button on the back of the router, and then you have to press the reset button for at least 20 seconds. You need to wait later for the router to be reset and establish a connection with its servers.
