TP-Link TL-WA801ND WiFi N Access Point 300Mbps PoE passive 30 m detachable 5dBi antenna x 2 - Wireless (Personal Computers)
I used this TP-Link as a WiFi access point and therefore connected by about 40m Ethernet cable to a box. Good range, no particular concern for commissioning. I only regret that it can not serve as a switch.
