LAN cable connection for Windows 7 and XP

We provide a small configuration tool* for Windows users that will set up your cable connection for you. You simply need to download and run it on your computer.

If the configuration tool does not work for some reason, you can also set up your connection manually.

Configuring your LAN cable connection using the configuration tool

You can download the configuration tool here.

Start by right-clicking/selecting “Run as administrator”. If you’re using Windows XP, you might have to log in as administrator first.

Press any key. The configuration will start automatically. Press any key to finish the configuration process once the tool asks you to.

Click on the balloon tip which will ask you to enter additional information.

Now you can enter your user information ( and your email password).
