Has anyone else with an LG Optimus Chat run into this same issue? When the phone has Wi-fi enabled, at some point when the phone sleeps it eventually loses its wi-fi connection even though I've set it for wi-fi to not sleep (in settings). When you look eventually in settings, the wi-fi connection is no longer connected and it says it's disabled. I've done some research, and it appears to be a common issue in Froyo. I'm just wondering if anyone else has run into this issue. I don't have this problem with my Nexus S, but then again, I'm running Gingerbread on it.
