The successful and hassle-free setup obviously requires some things. These are collecting the prerequisites, making the extender ready for setup, and following the directions carefully. Although the Linksys ac1200 setup does not require any specific things there are only a few basic items. That includes the extender and its default login credentials along with its web/IP address. Your router and its network SSID name and password. Lastly, any device with access to the web browser and the app store. While talking about another or the second process that is turning the extender prepared for setup, it involves a few steps. 

First of all, go through the extender manual quick setup guide to get its default details to proceed with the further process. Later, plug in the extender to a power socket which must be closer to the router’s socket. Make sure the power LED is in its ideal state and showing an optimal sign. Then, connect your device to the extender default network from the wireless network list. On the contrary, you can choose a wired connection to get stable and strong signal transmission. Lastly, access the setup window and follow the directions carefully to finish the setup.
