I recently set up a Deco M4 Whome Home Mesh Wi-Fi Unit. I used my smart phone to set up the main Deco and the satellite Deco. I thought everything was working well because I can access the internet on my phone through the Deco unit; however, when I tried connecting my laptop and desktop and other devices through Wi-Fi from the Deco Unit, the other devices cannot connect and it says that my password is incorrect when I am entering the exact same password for both my smartphone and the other devices. The other devices can access the internet by connecting from other Wi-Fi signals emitted by our old Wi-Fi extender but it cannot connect through the Deco units. 

What is happening? Why is my smartphone the only device capable of connecting through the Deco?
