wireless networking. The TEW-637AP, thankfully, takes a different approach. Instead of chucking your current router, the 300Mbps Wireless "Easy-N-Upgrader" just jacks into an extra Ethernet port on your existing router, and relies on that old box to do the "routing" part. The TRENDnet unit deals with blasting the 802.11n with MIMO, for theoretical speeds up to 300Mbps. Seems a bit silly, but the $64 pricetag certainly bests your average 802.11n router, so it might work out for you if you've got a good thing going with your existing setup, and just need a little extra push in the bandwidth department.
