Wireless Network Key (WEP/WPA) Recovery

It frequently happens that one loses or forgets his/her wireless network key. Normally this key is cached on your computer and it connects automaticly, but what to do when you have a new computer and you can't remember the key you originally used( and you don't have access to the wireless router) ?

Instead of resetting (the password on) the router you could try and recover the key from another computer on the network which does succesfully connect to the network.

One of the tools which can do this for you is NirSoft WirelessKeyView (http://www.nirsoft.net/utils/wireless_key.html). It's free, safe and easy in use ... just download the right version (32 bits or 64-bits) onto the computer which does succesfully connect to the network and run it.
