If you have lost your password or have never known it in the first place this is a great way to find it out!
First you will need a computer with an ethernet or LAN cable, plug this into the router to get started.
Next open a browser and go to http://192.168.1.254/ (or click on this link), if an admin box pops up the default username and password are both ‘admin’.
Now under the heading ‘Home Network’ click wireless then up the top right click ‘configure’ .
Your wireless password is now where it says ‘WEP Encryption Key’ or ‘WPA-PSK Encryption Key’
