Techgage posted a review of TRENDnet's wireless N extender.

Glued to your current wireless setup but want to make the leap to 802.11n? With the TEW-637AP, it's very possible. By adding this to your existing network, you open up all of the "n" benefits, while retaining all of the settings on your current router. Is 802.11n worthy of such a unique upgrade?
