If you are having problems with your Linksys RE6400 equipment, performing a factory reset on the device may help cure the issue. Be aware, however, that resetting your Linksys RE6400 will delete all configuration settings, including the name and password for your WiFi network. This is a crucial point to keep in mind. You will need to start the setup process for your Linksys RE6400 all over again. Find the button labeled "Reset" on the device you want to reset, in this case, a Linksys RE6400.

While holding down the reset button, wait for the power indicator light on the router to begin flashing. This should take roughly 10 seconds. This suggests that the router's settings have been correctly restored to their factory defaults. After you have performed a factory reset on your Linksys RE6400, you will be able to continue configuring the device with the help of the Linksys RE6400 Setup instructions. In order to accomplish this, you will need to connect the RE6400 to your modem, configure the settings for your WiFi network, and generate a new password for the Linksys device.
