To configure manually, connect to the Wi-Fi of the extender and visit `http://extender.linksys.com`, then follow the on-screen prompts. Once attached, move the extender to the optimal place. This is for the RE6800; however, Linksys RE6800 Setup is similar to the aforementioned, so you can similarly have better Wi-Fi coverage in homes or offices. https://linksys-wifi.com/linksys-re6800-setup/
