The ESR-9710 is a compact box of tricks that incorporates an 802.11n wireless access point that's Draft 2.0 compliant. Sensibly, the router has a quartet of switched Gigabit Ethernet LAN ports so if the claimed 300Mbps wireless-N speeds were ever actually achievable in the real world you won't have the bottleneck between WLAN and LAN systems that routers with slower Fast Ethernet ports will create. For Internet access you have an RJ-45 WAN port so you'll need an external cable or ADSL modem with an Ethernet port.
