encrypt wifi on Android? CM Security app on my galaxy 5 has an alert telling me my phone is RISKY, the wifi is not encrypted. How do I encrypt the wifi on my phone? I haven't tried anything because I do not know what to do.
It's telling you that the wifi network you are connected to is not encrypted, not your phone.  Most open hotspots are not encrypted, it's just warning you of that fact.  If you are on your home personal wifi, research how to enable WPA2 on your router.
