Note: the adapters will remember this key even if they are unplugged from the mains. The two adapters should locate each other and agree a shared key. You then do the same with the other adapter. The basic idea is that you put one of the adapters in a receptive mode where it listens for another adapter trying to establish a connection. If they don’t automatically establish a connection then you will need to intervene and manually initiate pairing. This means that when you plug them into your mains socket they will establish a connection between themselves, and form a logical network. Normally you buy adapters in pairs, and the manufacturer will normally ship each pair with a common NMK. To build a powerline network you need at least two homeplug adapters. This key is used to encrypt the data on the network using 128 bit AES (AV2 standard) or 56 bit DES (AV1 standard).

To overcome this powerline adapters form logical networks based on a security key or password called a NMK (Network Management Key). This means that in a neighbourhood of houses that all use powerline adapters there is a potential security risk. Powerline adapters share the same physical media (the mains cable). Having a basic understanding of how the powerline network works is crucial to troubleshooting problems, and for building,repairing and upgrading them. Note: Coexist means that they do not interfere with each other when plugged into the same mains wiring system
