My Bionic on home wifi always worked for me flawlessly. Now yesterday andtoday it stops, 3g (all I have here in this area) begins to start, then the notification bar tell me a "wifi service is available" and it starts again, after, of course, a lag in the time it takes to shut down 3g and reconnect to my wifi. In the meantime, I have no connection. it happens frequently, starting yesterday. Any ideas what this might be caused by? Anyone else experience this?
