The Linksys extender's firmware can be updated in two distinct ways. The Linksys WiFi app is used for the second one, and the web interface is used for the first. You must upgrade the firmware and access the portal in the first step of the process. This is obviously the manual approach that needs your help. However, there is another way that achieves the same result without requiring you to follow any procedures. Once your Linksys re7000 setup is complete, you will see the Auto-Update option when you open the WiFi app. You may enable the option to automatically update the firmware by clicking on it. This eliminates the requirement for you to carry out the process on your own.
