Make sure the channel is more than 1. As 1 indicates 0 devices connected to the wi-fi. Greater the channel lesse the amount of time neede to hack.
4- Collecting Logs:
Now is the time to collect logs. After you have like more than 100,000 packets of data captured then go to the logging tab and click concentrate logs. Now select all the files and save them. It merges all the logs into a single log file. Save this file some place and then open it up in log viewer. Now within logviewer go to import and then select wireshark or .cap format and save the file.
5- Getting the Key:
This is the main part. Now we will use the captured packets to crack the wi-fi. For this we will use the aircrack-ng GUI. A great software. Really this is the best friend of a penetration tester. Now you can get it from here. Now after downloading open the aircrack-ng GUI.exe. Now select the .cap file which we saved later. Lauch the attack and then follow the on-screen instructions. You will get the key pretty shortly. And if not then try to re-do step 3 and capture the packets again but this time capture more packets then what you captured previously.
This concludes the article to tell you how easy it is to hack WEP. Hence never ever use WEP to save your wi-fi from others hands.
