I've got a network that no Android device can connect to. I've tried many. iPhones, iPads, laptops, PCs, they all work just fine. But Androids, no matter what type of branded OS they have, will not connect. After entering WiFi connection details, I get the message "Authentication Problem". The problem isn't the password, it's something with the WiFi Access Point (Motorola AP 5131, using release version 1.1). I can't begin to diagnose or fix the problem, until I can find out what "Authentication Problem" actually means. Is there a way to view a log of some sort to find out what the actual problem is? I'm on Lollipop 5.01, Kernel 3.10.61. WiFi authentication is WPA/WPA2 PSK. The device is a Lenovo TAB 2 A10. I don't know exactly what parts of it are branded in the package.
