Repairing or tweaking an Internet connection can be quite the troublesome experience sometimes. It may take a long time before you resolve the problem or find the setting that normalizes your Internet connection speed. And while you normally cannot get more out of the line than you have subscribed to, you can make sure to get the most out of the connection whenever you connect to the Internet.

Auslogics Internet Optimizer is a free tool that tweaks several system and application specific settings to improve the speed and reliability of the Internet connection.

Before you use it to tweak your connection, you should consider running speed tests to see if there is room for improvement. See the articles Internet Connection Speed Analysis, Internet Connection Reliability Test and the Speedtest review for programs that can aid you with the task.

The program, that is also part of Auslogics' commercial performance software BoostSpeed, offers two modes of operation. Inexperienced users can let the program handle all the optimizations by simply selecting an Internet connection speed from the list. Available for selection are Slow (128 kbps or lower), Average (1 mbps or lower) or Fast (over 1 mbps). The program optimizes the system and applications for the selected speed in this case.

The manual atomization mode reveals all settings and values the program can make changes to. The Internet Optimizer displays the most important settings at the top, followed by detailed global and application specific parameter listings.

Internet Explorer, Firefox or Opera users can for instance change the number of total and per server connections easily.

A click on a browser listing opens roughly ten parameters that can be modified to speed up the Internet connection. This includes disabling prefeteching or IPv6 in Firefox, the network buffer size in Opera or enabling TCP Autotuning in Microsoft's Internet Explorer.

Most parameters are listed with descriptions that aid the user in the configuration. Inexperienced users will however have difficulties picking the optimal value for their Internet connection.


Auslogics' Internet Optimizer is a useful program for users who experience Internet connection speed or reliability issues. Automatic and manual modes make the program interesting for users of all experience levels.

Windows users can download the latest version of the program from the Download Crew website. (via Techdows)

    An even quicker way to open Task Manager is by pressing Ctrl+Shift+Esc.

    Win+Pause used to be the goto shortcut for me since… W95… Ms recently hijacked it and you now get Sysinfo. Device manager is still accessible this way: the second to last link at the bottom.
