If you are experiencing slow or nonexistent downloads or uploads using BitTorrent, enabling encryption in your BitTorrent client may help. Note that if you are not experiencing slow speeds, enabling forced encryption will probably only slow you down.


µTorrent is a popular BitTorrent client for Windows. Enabling encryption in it is easy.

First, choose Preferences from the Options menu:


Then click BitTorrent at the left, then choose Forced from the Protocol Encryption: Outgoing dropdown menu:


Then click OK.

Although you may also simply choose Enabled to let µTorrent choose when to use encryption, if your ISP is using so-called "traffic shaping" to slow down your BitTorrent traffic, this may not be as effective as choosing Forced.
