That does make this description of the UPDATE seem somewhat misleading. Why would Apple not just describe the update as a security fix, instead of suggesting that the update "blankets your space with a blazing-fast, secure wireless network"? (Yes, I know it later goes on to talk about the Airport Extreme, but that's just a way of building in a little advertisement).NotebookReview was wrong. Check the discussion for a link to http://www.appleinsider.com/article.php?id=2443
Admittedly, I have not tried to connect with a pre-N router, since I do not have one. Has anyone with a pre-N router tried this update yet?
About AirPort Extreme Update 2007-001
The perfect wireless solution for home, school, and business. As it blankets your space with a blazing-fast, secure wireless network, it opens up a world of possibilities for home entertainment, backups, printing, and more. With the AirPort Extreme Base Station, you and up to 50 of your friends, colleagues, or family members can enjoy a robust wireless network offering up to five times the performance and up to twice the range of networks created with the earlier 802.11g standard.
Anyway, this is hijacking the discussion of the rumored Apple event, so I will defer any further discussion of this to the appropriate thread.
