We got our new Airport Extreme 802.11n today. We decided to deviate from our standard modus operandi and run some benchmarks before we took it apart. (I know, I know-- our screwdrivers were lonely for a while.) This image is a sneak-peek to get your appetite whetted.

The new base station is amazing. We achieved a 10x performance boost, and a 3x usable range increase (significantly better than Apple's 5x/2x claims). Actual benchmarks are on the next page.

Included: Base station, the famous $1.99 install CD, smallish power brick, and a manual. No USB or ethernet cables.

Our office is a little bit spread out-- we have two snow 802.11g base stations and two Airport Express units. We may be able to replace them all with just one new base station!

From bottom up: Mac Mini, new base station, old base station.

The device feels very sturdy, and weighs a bit more (1.70 pounds) than the old base stations (1.22 pounds).

We transferred two 35MB quicktime files (70 MB total). The first location was 5 feet from the base station. With the G base station, we had a reported comm quality of 56, and with the N base station the commQuality was 76. To get the commQuality, run the command `/System/Library/PrivateFrameworks/ Apple80211.framework/Versions/Current/ Resources/airport -I`.

There is a rubber pad covering the bottom attached by an adhesive. To get into the base station, you have to peel the pad off.

There are five Phillips #0 screws underneath the pad you need to remove.

This is the top of the logic board. Interesting things: 3V (clock?) battery, two Samsung memory chips, and imprinted Apple part #820-1942-A. The processor is covered by a heat sink.

This is the bottom of the logic board. Not much to see here--something large covered by another heat sink. At the top right is a plastic cover over the LED. Four ethernet ports, one USB port, a power jack, and a reset button. The Apple part number on the airport card is 603-9396-A.

try heat shrinks
My 3rd gen extreme stopped working... No LED indication at all. Tried factory reset, no joy. No LED light illuminates, although It appears the power supply does push juice to the unit somehow, because only indication I have that there still may be life in it is that all LAN inputs blink in unison. Any thoughts? Reparable? Or BER (beyond economical repair)? Unit gave no indication of performance degradation before it stooped working.
i have a ipod and a mac mini and airport extreme
