Re: WI-Fi Password how it hacked
Not really. A good hacker will be able to figure out the network in no time. What does help though is reducing the size of the network. IE rather than using your normal /24 from your router/DHCP consider making the network smaller. Maybe /28 depending on how many IP’s you require.
Likewise the frequency the AP is on is also immaterial. As long as the radio is on its broadcasting. Thus any receiver should be able to pick up the range and the SSID even if the name is being masked (which also doesn’t help).
WPA and WPA2 are more than strong enough for this task as the password is not sent in clear text over the wire like the old WEP hashes which were always inferior. Whilst its easy enough to brute force simple pass phrases ensure you use a strong password with a combination of numbers,capitals,and letters.
