TP-Link TL-WPA4220
Linking your wired and wireless worlds.
Squeezing a Wi-Fi access point into the Powerline adapter, the TP-Link TL-WPA4220 makes it easy to bring both a wired and wireless connection to remote corners of a house. The units are rated for speeds up to 500Mbps, using the HomePlug AV standard and a 10/100 Ethernet port. The Wi-Fi half is 802.11n only, and good for up to 300 Mbps. They are also fully compatible with other HomePlug AV spec devices.
Back in the real world, we managed 71 / 69 Mbps up and down, and a maximum of 59 Mbps on Wi-Fi, in the same room. Setup is the usual plug-inand-press-the-pair-button, which also turns on 128-bit security. To make extending your existing Wi-Fi easier, the adapters have a Wi-Fi clone button, which copies the existing router configuration and is good to go. They also have a three colour LED, which indicates the quality of the network connection at the current location.
$109 gets you a twin adapter kit, or you can pay $69 for an individual unit.
