|If you've forgotten your wireless password you might have to change it. |
Log into your router's management interface (instructions in manual) and find the wireless setup page. You'll want to look for the Encryption Key setting, that's the password in question. If you're lucky, it'll show you the password in clear text and you'll know it and be able to connect new devices using it. If however, it doesn't show it in clear text you will have to change it.
However...........if you change that key/password, any and all wireless devices presently connected to the network will need to connect with the new password as well.
It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
