I found an amazing trick which helps you to prevent the internet from disconnecting while downloading.
Many people have this problem, including me that the internet disconnects while downloading. To activate this trick, you have to make some changes in the router.
I got this modem with my broadband connection. It used to give me troubles, but now, i can face them well.
The modem has default IP address 192.168.1.1. The computer IP address can be set to any in the range 192.168.1.2 to 192.168.1.254. The DNS is to be set to 192.168.1.1.
The first major difference i noticed on the first day that this modem get hot in minutes. I have seen many but all are the same in case if generating heat. But this is little bit hotter.
