During my search on “How to show the Library Folder on OS X Lion” I found an nice article talking about a hidden Wi-Fi Diagnostic Tool in OS X Lion, and after a few tests, I thought that it was a good idea to publish it on my blog as well.
In Mac OS X Lion and Previous versions, a tool for connections test was existing (e.g. Utilities -> Network Utilities ) but it was not dedicated to Wi-Fi. However this one is, and is accessible at :
1 |
/System/Library/CoreServices/Wi-Fi\ Diagnostics.app/ |
To access it :
- Open the Terminal
- Copy, paste the previous Link in the Terminal preceded by “open”
1 |
open /System/Library/CoreServices/Wi-Fi\ Diagnostics.app/ |
- Press Enter
You should see the following window appear on your screen (Open your Wi-Fi):
As shown above, you will have the choice between four options, lets resume them fast :
Monitor Performance:
This option will give you a few information about the Wi-Fi connection you are using, and the signal rate etc ( such as shown in the print screen below )
You will the be able to export all the data into a PLIST (XML) file.
Record Events :
This will allow you the possibility to monitor all the events appearing on your Wi-Fi. ( This could be useful when you know that a friend is trying to hack your Wi-Fi for fun )
In this case you will be able to export everything as well in a Plist file.
Capture raw frames :
This option will allow you to capture data going on the network, going to and from your computer, or data that could be listened on other networks :
Below You might see the capture Process :
To see the data, you will have to click on continue and export the data, finally a ZIP file will be created with a Plist file and a PCAP file that you will be able to open with a tool such as wireshark.
Turn On debug logs :
This option is just a log system about your connection. Most of the information received are kernel calls.
Now you will be able to monitor your Wi-Fi connection in the best way.
And that’s it.
