We talked about inSSider, A wifi locator which can help you in finding the WIFI on the move but then you need to keep your monitor and lid turned which drains your battery life. QuickLZ came up with an application on top of this application which confirms that WIFI is available when it starts singing Ding Ding Ding Ding!! lol funny but lot more practical.
This is exactly what you should do
WIFI locatorJust start it and begin walking. You can optionally close your laptop lid or turn off the screen to save battery life – this tool guides you by sound too!
When you hear a ding, stand still and wait. Next you’ll hear either a hihat or a “ding ding ding ding”. The hihat means that it failed connecting and that you must carry on walking.
This is similar to my Dell Laptop wifi finder, which I connected to my Router, which doesnt make sound but light continuously blinks when it finds wifi near by. Download Wifi Scanner and Ding Ding Ding Ding.!!
