If you want to know how you can reset your Att wifi router, then you have to follow some needed steps carefully such as hold and press the reset button on your keyboard approx 10 seconds. When you let go before finishing the 10 seconds, then the gateway will reboot automatically. In case, it does not reset. Then you have to wait unless the gateway restarts & all the status light are on. For more info join Att Customer Service. 1-833-276-4777 http://attcustomerservicephonenumber.com/
