Time Capsule (WPA -> WPA2)

[Mac-lover3]

Hello everyone

A while ago I changed my home Wi-Fi from WPA to WPA2 for a little more secure network. But since then my Time Capsule keeps having a flashing amber light. No matter what I try in Airport Configuration.

I'm using a MacBook Air (2011) with El Capitan

Thanks in advance
