The 2007 update
On January 9, 2007, Apple's AirPort Extreme began shipping with support for the 802.11n draft specification and a built-in wireless print and storage server. This was the second generation of the AirPort Extreme, which was first announced at the MacWorld expo in San Francisco on January 7, 2003. The 2007 update featured a new flat, rounded rectangle shape, similar in layout and size to the Mac mini or early models of the Apple TV.
On April 23, 2007, Apple issued an update for the AirPort Extreme Base Station with 802.11n, which included "general fixes, compatibility updates, and security improvements." This update was in response to two security issues. The first issue involved improper default IPv6 configurations, which could potentially expose network services on local machines to remote attackers. The second issue allowed local users to view the filenames of a password-protected AirPort Disk without entering a password. In addition to these security improvements, the update also provided modest improvements to AirDisk speeds.
Despite the improvements brought about by the 2007 update, some users reported experiencing connection problems after installing it. These issues included difficulties reconnecting to wireless networks after waking their machines from sleep and sudden drops in wireless connections. However, the update did reduce the number of dropped connections for some users when connected to AirPort Base stations.
Overall, the 2007 update for the AirPort Extreme with 802.11n specification brought several enhancements and security fixes, but it also introduced some network connectivity challenges for a small number of users.

Performance and speed
The 802.11n protocol is a wireless networking standard that uses multiple antennas to increase data rates. It is an amendment to the IEEE 802.11-2007 wireless networking standard, which was first introduced in 2002 and published in 2009. The purpose of the 802.11n standard is to improve network throughput over the previous 802.11a and 802.11g standards, with a maximum data rate increase from 54 Mbit/s to 72 Mbit/s with a single spatial stream in a 20 MHz channel.
The 802.11n protocol achieves this improvement in performance and speed through various methods. Firstly, it introduces multiple-input multiple-output (MIMO) technology, which uses multiple antennas to increase the amount of information that can be transmitted. This is done through spatial division multiplexing (SDM), which multiplexes multiple independent data streams. Secondly, 802.11n adds support for 40 MHz channels in addition to the 20 MHz channels used by previous standards, allowing for a further increase in data rates.
The actual speeds achieved by 802.11n networks depend on various factors. Under best-case conditions, 802.11n connections can theoretically achieve up to 300 Mbps of bandwidth. However, in practice, these connections often operate at slower speeds, such as 150 Mbps or less. The speed may also depend on the number of antennas used, with 802.11n capable of achieving up to 288 Mbit/s with four antennas in 20 MHz mode, or 600 Mbit/s with four antennas in 40 MHz mode. Additionally, the presence of other Bluetooth, microwave, or Wi-Fi emissions in the area can affect the speed, as can the distance from the communicating devices and their output power.
The Airport Extreme is a line of residential gateways made by Apple that combine the functions of a router, network switch, wireless access point, and NAS.
