2. Crack yourself the CAP file you sent to us with the command :
aircrack-ng -w wordlist.txt my_cap_file.cap
- "wordlist.txt" is a text file which contains the password we gave you ;
- "my_cap_file.cap" is the .cap file you sent to us with handshakes.
3. Aircrack-ng will show you the password ! If not contact us.
If aircrack-ng confirms the password, but you still cannot connect to your Acces Point, it indicates that some other ways of authentication are needed, or other means of protection are enabled (MAC filtering, number of clients connected, etc), or the AP owner changed the password.. Of course, we cannot help you about these local protections.
Note that you can do the same with hashcat tool. The command line would be: hashcat -m 2500 file.hccapx wordlist.txt
