While Microsoft Windows 7 is the mainstream Windows OS in use now, people still prefer and use Windows XP. I recently came across an Windows XP specific issue, where the computer detected security enabled WiFi networks but failed to connect with them as shown below.

As evident from the error message above and pretty descriptive error-icon shown below, Windows XP SP2 is having issues trying to negotiate security certificate. To fix this, enabling WPA and WPA2 encryption support on Windows XP in Wireless Group Policy (WGP) we need to install KB917021 update from Microsoft.

After completing internet connectivity setup on Raspberry Pi, it's time to setup a fixed/static IP so we can access it easily over a network via SSH and VNC.

To get this done we will be using another popular, simple to use, graphical WiFi Network management Utility for Linux - WICD Network Manager. Just follow the steps below to install and configure an static IP on your Pi.

After initial setup of the Raspberry Pi, it's time for an internet connection. While using Internet over Ethernet is just plug-n-play business on Raspberry Pi, setting-up an Wireless connection takes a little more effort.

To get started with WiFi, first we need to connect an supported USB WiFi dongle to the Pi. Make sure you are using an Powered USB Hub (shown in the picture below) as Raspberry Pi is not able to reliable power multiple USB devices, follow the instructions next to configure your WiFi dongle on the Pi.
