PowerLine AV 500 3-Port Passthrough Adapter



The DHP-P338AV at a Glance

The DHP-P338AV Powerline AV+ 3-Port Passthrough Adapter, compliant with the HomePlug AV standard, uses your home’s existing electrical wiring to create a network or extend your existing network. It turns your power outlet into a network connection to access digital media devices, game consoles, print servers, computers, and network storage devices throughout your home.

Ideal for Bandwidth-Intensive Applications

The DHP-P338AV features Powerline AV+, enabling it to deliver data at speeds of up to 500 Mbps, much higher than regular Powerline AV products. This rapid transmission speed makes it ideal for bandwidth-intensive applications, providing smooth HD video streaming, VoIP calls, and lag-free online gaming experiences. The DHP-P338AV also lets you connect up to 3 Ethernet devices to take advantage of its high speeds. It utilizes port-based Quality of Service (QoS) to set priorities for transmission through each Ethernet port.

Convenient Setup and Secure Operation

Setting up the DHP-P338AV is as simple as plugging it into a power outlet and connecting your device. The built-in Passthrough socket enables you to plug a device into the adapter to continue using the electrical outlet. The Passthrough socket features noise filtering which helps prevent signal noise from an electrical device plugged into the socket from affecting your Powerline connection. Extend your home network by connecting multiple devices in the farthest corners of your home, or for additional connectivity, attach a switch or wireless access point to the adapter. For convenient setup, you can quickly configure an encryption key with the simple push of a button. The adapter implements 128-bit AES data encryption to protect your network from unauthorized wiretapping. With hassle-free plug-and-play installation and easy security setup, the DHP-P338AV is an ideal solution for creating a wall-to-wall home network.


The DHP-P338AV incorporates an energy-saving mode to comply with the European Energy Using Product (EuP) Directive. If no data transmission or reception occurs over a certain period of time, the adapter will automatically go into sleep mode to save power, reducing power usage by more than 70% and allowing you to save energy automatically, without sacrificing performance. D-Link Green Technology allows switches to automatically detect the link status and reduce the power usage of idle ports.

Extra Passthrough Power Socket

The DHP-P338AV also features an extra passthrough power socket to ensure
that your electrical outlet remains available for use by an electrical device while the Powerline adapter is plugged into the socket.
