ASUS PCE-N15 Wireless-N PCI-E Adapter Review
 

The PCE-N15 Wireless-N PCI-E Adapter from Asus provides a way to alleviate some of the tangled monstrosity that is networking. The PCE-N15 Wireless-N adapter boasts a top speed of 300Mbps and dual antennas that operate on different frequencies to help deal with areas that have a lot of other Wi-Fi networks. It all seems like the standard affair for a wireless-N card these days, except for nifty little mode called "Software AP" which allows it to act as an access point for other devices on your network. This way you can either extend your existing network or add wireless without more cables and a new router
