I have the ZTE Blade Z MAX Worked great for 2 months. The SSID disappeared from the local list. My Desktop and Laptop still work fine. I enter the ID and hit save nothing happens even if I add the Password. I also did a restore on the phone plus the same on the router. I followed the setup Wifi post but nothing happens. I guess I need someone to guide me through including Data. which is working. What to do?
