The Xbox 360's aging and overpriced 802.11g based wireless adapter is about to be widely replaced by a new 802.11n capable model, as discovered on Costco's online store in which it is currently at a slightly discounted price of $88.

The new model has two antennas for superior signal quality and transfer speeds. Also, the wireless N speeds should give users the ability to wirelessly stream 1080p content from the upgraded Zune movies collection without a hitch.

Costco has said the adapter is scheduled for shipment as of November 10.
