Linux operating systems comes with various set of tools allowing you to manipulate the Wireless Extensions and monitor wireless networks. This is a list of tools used for wireless network monitoring tools that can be used from your laptop or desktop system to find out network speed, bit rate, signal quality/strength, and much more.
#1: Find out your wireless card chipset information #2: Find out wireless card driver information #3: Disabling wireless networking ( Wi-Fi ) #4: Configure a wireless network interface #6: Gnome NetworkManager #7: Say hello to wavemon #8: Other options
I want to know if there exists any command line option or GUI tool (Ubuntu 11.10) so that I can measure the strength of wireless signal at a given location. I have a house where the wireless is not easily accessible at all corners I want to know at which corners or rooms the signal is weak.
The answer is in the linked article:
iwconfig wlan0 | grep -i --color signal
To be sure of which the name of your network interface is (not necessarily wlan0) maybe first find it with the follow command:
route | grep default | grep -o '.....$'
