Darnit! Was having problem connecting to home wireless. It just doesn't want to connect. That has cut my Internet off. Double check wireless card settings, the wireless key, everything seems to be ok. But the darn thing just don't want to connect.
Finally, trying one last thing. Shutdown & restart my laptop. Hey! It got connected instantly when the notebook booted up. Hmm, seems like lots of problem related to windows can be solved by rebooting the pc / laptop.
