You lost your PSK (PreShareKey) to your wireless network ?

Guest Blogger

So you lost your PSK (PreShareKey) to your wireless network and you don't have access to your infrastructure to recover it? I recently received that frantic call from a customer. The only admin who had access to the key recently found employment elsewhere. They also didnt have access to their controllers to quickly gain access to the key. Thats a different matter all together ... 

 

In the past with older OS’s you had to run special programs or snoop in the registry for the PSK key. Assuming you have admin access to your box you can simply browse to the PSK.
