Many times to see the network activity on my computer, I have to get up from my chair and peep behind my monitor to look at the router to see if any activity is going on. I was just searching if there was a way to monitor using the hardware indicators like keyboard LEDs. After Googling for a while I found this wonderful free tool called Network Lights that allows you to convert your keyboard Scroll Lock and Num Lock LEDs as Network activity indicators.
This utility is pretty small and works out of the box, there is no installation required. When you run this utility it sits in your system tray and immediately you will be able to see that the keyboards Scroll Lock and Num Lock LED’s are now acting as network activity indicators.

The the blink rate of the keyboard LEDs can be controlled from the
options that is provided in the program. The default blink rates is
100ms, if you intend to increase or decrease this then you can change
it from the options that is provided.

Also you can view your network statistics using this program.

This utility works in Windows XP and Windows Vista. This is pretty
useful program that I needed and has found a place for itself in my
software collections.
