A power supply module 100 is connected to a network client device 130. The power supply module is capable of powering said network client device, wherein the power supply module has a data memory 104 containing security information 126. The power supply module transfers the security information 126 from the data memory to the network client device. The security information may comprise a network key and/or a passphrase for generating a network key. The security information may comprise network parameters. The network may be a wireless network and may further be a secure wireless network that is at least partially in a restricted environment. The network may be a wireless gas sensor network. The security information may be used to encrypt and/or decrypt data sent over a wireless network. A commissioning device may write the security information into the data memory. The commissioning device may generate the security information. The security information may comprise a unique identifier for the network client device. |
