I am sharing Wi-Fi with my landlord. He allowed me to connect to his AP. The Wi-Fi AP occasionally becomes off because his son puts the LAN cable directly to his computer when he plays online shooting game. This absence of the wireless network usually lasts for one or two hours.
It was yesterday that wireless connection was broken when I was watching a youtube clip. I waited two hours but the connection was not recovered. Then, I found myself getting nervous and being able to do nothing.
I had some movies stored in my hard disk, some books which I brought from the vacation, and papers to read, which means I had lots of things to either entertain or work without the Internet connection.
Interestingly it was after the connection restored when I was able to read a book! I need to beware of Internet addiction :)
