3. 4) Now you will see the screen shown below as they collect packets. I have read tutorials
claiming that a minimum of 5000 packets is needed. But in my experience, iv had to collect at
least 15,000 packets before successfully cracking it.
Note : The packets are secondary, What is actually happening here is that we are trying to
collect as much IVs (Initialization vector) from those retrieved packets. The more IVs collected
the higher the chance of cracking it. So if you collected 5000 packets but have shit loads of IVs in
them, Then that is all you will need. But if the IVs is limited then you might have to go for 15,000

4. +++++++ packets. Do the Math.
5) Now that i have collected around 50,000 packets, i proceed to click on the “blue stop button.”
Next click on the “Logging” tab to check where the packets were saved on your hard drive. In my
case its saved on my desktop. Or if you prefer in the future do this setting before starting.

6) Now minimize Commview and locate the logged packets on your hard drive. Once you have
found it, double click on it and a screen will appear. Click “File”, “Save as” and change the output
