Read my review at Macworld.com of the new gigabit Ethernet version of the Apple AirPort Extreme Base Station with 802.11n (Extreme N): Apple updated their Extreme N last month with auto-sensing gigabit Ethernet on all four included ports, but that’s not all they goosed. As I suspected, the internal 10/100 Mbps Ethernet support limited the device’s top rate, which I measured at about 90 Mbps whether a single stream from an 802.11n-equipped Mac to another such machine or to a wired LAN Mac.
With the new gigabit Ethernet base station, the maximum Wi-Fi to Wi-Fi speed remains the same, but the Wi-Fi-to-LAN rate shoots up to 140 Mbps when gigabit Ethernet is on the hardwired side. That’s in 5 GHz with wide channels, which is the ideal case. I had poorer rates in 2.4 GHz, but that was because the RF environment where I was testing apparently got worse since February, when I reviewed the first version of the base station.
Speed was improved overall, including in LAN/WLAN to WAN (that’s Wi-Fi over the WAN port or LAN Ethernet over the WAN port) when network address translation (NAT) is enabled from 30 Mbps with Wi-Fi and 60 Mbps with Ethernet to 50 Mbps and 70 Mbps, respectively. If you’re using the base station as an access point, handling NAT elsewhere, then the speed isn’t capped at all.
This is a Wi-Fi base station through and through now, by the way; as noted a few days ago, Apple updated their firmware to a certified Draft N release.
