When you want a more direct-connection between your motherboard and your wireless internet, the 450 Mb/s 2.4/5GHz Wireless N Dual Band PCI Express Adapter from TP-Link could be all you need. With its 802.11n standard, and 802.11a, b, or g backward compatibility it will easily replace any old wireless adapters without reducing any wireless functionality. Upgrade from one of these older technologies, and get the high-speed benefits of wireless connectivity at up to 450 Mb/s--great for HD video steaming or online gaming.

In addition to the convenient backward compatibility, its dual 2.4 and 5.0 GHz bands provide more options when it comes to wireless channel support. Your neighbors could be using the same band and channel you are, so by simply switching to a lesser-used one you can dramatically improve your network's performance. This added performance is also helped by the three separate antennas that are connected to the adapter to greatly enhance the sensitivity to the wireless in your home or office.

Not only will your network be faster, but it can also be much safer with this adapter--thanks to the various security features supported. For example, WPA and WPA2 encryption standards ensure your wireless connection is safe from intruders.
