According to the Quick Start Guide, one should enable encryption by adding a password to the D-Ext band settings, and this results in a blue LED on the MoCa status light.
However, I have also added a password to the D-Low and D-High items, and now the LED is white.
I'm mostly just curious what is the difference, and should I not have a password on D-Low and D-High?
LED white is not correct. If the encrytion is enabled, it should be Blue.
The default band is D-ext, you can enable encryption on D-ext. You also can enable encryption on D-Low and D-high, it doesn't matter.
