For a while my DINC2 would automagically connect to WiFi when I was home or at work but now it doesn't do so. I have to manually open the network settings and tell it to connect. When I do that it connects just fine and remembers the password so I don't need to enter it. I prefer to use the WiFi rather than the 3G connection as it doesn't affect data usage limits.
I'm not sure if this issue is a conflict with some app or what the problems is. I'm hoping someone here can give me some insight into what's going on. As I said above, for a while it would auto-connect but now I have to manually tell it to connect to each network.
