|I was thinking that since it will only take 24 characters then you will likely need to use a different Security type like WPA2 as additionally noted when I right clicked on your BlueRay name and selected Open in new Tab it shows more than shown below but...On the router configuration page:|
Click Wireless Security, just below Wireless. Change the security mode to
WPA2-Personal, then, enter a password of at least 8 characters in the pre-shared key/passphrase box. Save the settings.
Use your Blu-Ray to find your network, then, enter manual settings. Use these:
IP Address: 192.168.1.10
Default Gateway: 192.168.1.1
Connect with these settings and enter your WPA2 key when prompted.
End of excerpt.
You will need to change your password/passphrase on your other devices too.
