Whether you are looking for an alternative to PG2 because it fails to function properly, or simply looking to cut down the number of processes you are running – the information here is for you.

It is possible to block ip-ranges with utorrent’s built in ipfiltering system.

First and foremost, you will need the latest utorrent beta. Be sure to check this out if you are noticing degraded download speeds running utorrent in Windows 7. After you finalize your utorrent install, get a blocklist: a good place to get this is at BISS – get nipfilter.dat.gz, open with an archiver and extract the “ipfilter.dat” to C:\Users\USERNAME\AppData\Roaming\uTorrent or its XP equivalent of C:\Documents and Settings\USERNAME\Application Data\uTorrent .

A simple way of reaching the utorrent application folder, regardless of the OS, is by typing ‘%appdata%/utorrent’ in the run menu, without the quotes.

Right click > peer traffic logging > Log Blocked Connections in your Logger tab to see it in effect.

After getting windows 7 I noticed that my downloads of the Linux kernel through utorrent were running at incredibly slow speeds.

Though the reasons behind this may be complicated, the solution turned out to be rather simple.

The first solution is direct, and very simple. You need to disable UPnP port mapping in the settings of utorrent, and run it in compatibility mode for Windows XP SP2. For the uninitiated: right click properties of utorrent shortcut, head to compatibility, and make it look like the picture.

Now the second, optional, part will require patching of your tcpip.sys. As you may, or may not, be aware Microsoft introduced a half-open connection limit in XP SP2, and included it in Vista and Win7. As far as the official reason, it was done to hinder the speed at which certain trojans and viruses spread. The real result: slower torrent speeds.

This is very simple. Head over to http://half-open.com/home_en.htm and grab the Half-open limit fix 4.0. Patch it to whatever you need, and restart.

You may also unlock utorrent’s max connections; head over to preferences, Advanced, and find the string net.max_halfopen and increase the numerical value.
