As strange as it may seem to many of us, Microsoft started pushing out a small update ahead of the big feature update that is coming next month and that is currently in preview testing.

According to what we have been able to uncover, this update is targeted at the wireless adapter and it is said to add WPA2 encryption support. Our sources also tell us that it adds some additional necessary support for the upcoming new Xbox 360 Wireless N Networking Adapter that is set to arrive starting November 10th.

While it may seem strange not to roll this update into the upcoming major feature release that is slated for some time in November, it is likely with the new Xbox 360 Wireless N Networking Adapter arriving on the 10th that Microsoft needed to make sure support was in place before it started showing up on retailer shelves.

The addition of WPA2 support, while likely requested by some, will largely go ignored by the vast majority of Xbox 360 users. WAP2 support requires that both the wireless router/access point as well as the client device offers support for it. While most of latest generation wireless routers/access points support WPA2, a good number of previous generation products lack WPA2 support, although it can be added sometimes by updating to the latest firmware.

As you have likely guessed by now, the Xbox 360 Wireless N Networking Adapter that we told you was coming some months back is officially confirmed for release on November 10th. The current Xbox 360 Wireless B/G Networking Adapter will quietly drop in price $20 at most retailers shortly after they have the new N version of the adapter in stock.
