Many popular BitTorrent clients such as uTorrent, BitComet and Azureus can work right out of the box. Download, install, load a torrent file and it’ll start downloading. If you don’t tweak the configurations, most probably it’ll take you longer to complete downloading the torrent.
Slow to finish downloading a movie or file from torrent is not a big problem. The biggest problem I always encounter when someone in the same network as me downloading a torrent and all of sudden my internet connection has been cut off entirely. I am unable to browse the web, my MSN messenger disconnected and etc. Pinging the router gives me a “Request time out” error message.
This problem happens both in modem and router. To get back the connection, I need to disconnect and reconnect if using modem or restart the router if I am using a router. Restart the router is not a good solution because when the BitTorrent starts downloading when it detects connection, my connection gets killed again.
I’ll share with you how to configure uTorrent, BitComet and Azureus so that internet won’t get disconnected while downloading torrent.
This happens mainly because there is a large number of connections that BitTorrent utilizes is stressing out your router/modem. The default settings in BitTorrent client is normally more connections than cheap modems can handle. Since many of us are actually using the free and cheap modems provided by our ISP, we have to lower the global connections in BitTorrent Client.
For uTorrent
1. Go to Tools -> Preferences (or press CTRL+P) to bring up the preferences options.
2. Click on BitTorrent and set the “Global maximum number of connections:” to a lower number.

For Azureus
1. Go to Tools -> Options (or press CTRL+,) to bring up the options.
2. Go to Mode and select Advanced.

3. Next go to Transfer and set the “Max connections globally” to a lower number.

For BitComet
1. Go to Options -> Preferences (or press CTRL+P) to bring up the preferences options.
2. Go to Advanced -> Connection.
3. Set the “Global maximum connections” to a lower number.

You can try the value “100″ for starters. If your router is able to handle that amount without killing your connection, you can try adding 20 more. Continue until you find the limit.
Alternatively, you can get a better router such as 3Com or Belkin to replace your cheap router provided by your ISP. I’ve also heard that full bridging mode works but it’ll leave your computer more vulnerable to attacks. In this case you’ll need to install a firewall to protect you.
