Hi. We have deco m4 and we wanted to make some changes in the WiFi security. I downloaded and installed a beta firmware that enables us to access the web configuration. In the web UI, I thought that we can now change the wifi security settings but the UI only shows the status of the router. I also noticed that cpu usage is always at 100% even tho only one device is connected to the router. Do any of you guys have a link to a firmware that lets you change the security settings of the wifi? That will be much appreciated. Thanks!
