This bundle includes ZyXEL NBG-318S and ZyXEL PLA-401. ZyXEL NBG-318S features both wireless and HomePlug AV connectivity. You can always connect to the Internet wirelessly, even on some spots that couldn't be reached by the wireless network. With existing power lines, reliable connection can be provided through wall plugs. Now you can plan your home network, use the power lines as the network backbone, and then deploy the NBG-318S as the broadband extender to reach every corner in the house. The ZyXEL HomePlug AV PLA-401 is an extended access solution that allows your house to be completely networked using your existing electrical power lines. With no need for additional wiring, simply plug the ZyXEL HomePlug AV PLA-401 to an existing electrical outlet, then plug the second PLA401 to the outlet you want to have network connection, and it will transform your electrical power lines into a house-wide network infrastructure. It's the easiest way to extend the network connection from your broadband router.
