Carol, I am sorry but because of ethical and moral standard I cannot help you access this WiFi network because of the risk that you might not be authorized to access it.
If it's actually your Wi-Fi then you should have PHYSICAL ACCESS to the router which is broadcasting the signal. Given physical access you will be able to do anything and everything. That includes, easily reseting the router/password. That is what I suggest you do/would be easiest thing for you do at this point. Reset it and reconfigure it with encryption and a secure key. For best wireless security, choose WPA2-Personal with AES or TKIP encryption.
You can reset the device altogether and set a new password by holding down the reset button for a few seconds.
