These kits are ideal for providing strong speeds to areas of your home or office that have weak Wi-Fi signals.

They are easy to install and need essentially zero maintenance once setup.
This Netgear AV1200 kit is capable of speeds up to 1200Mbps and features beam forming technology for a stronger signal, HomePlug capability, as well as one-touch encryption. Amazon customers rate this Powerline Kit 4/5 stars.
