Xtreme N™ notebook or desktop adapter and stay connected to your network from virtually anywhere in your home.
TOTAL NETWORK SECURITY
The Xtreme N™ router supports all of the latest wireless security features to prevent unauthorized access, be it from over the 
wireless  network  or  from  the  Internet.  Support  for  WPA/WPA2  standards  ensure  that  you’ll  be  able  to  use  the  best  possible 
encryption method, regardless of your client devices. In addition, this router utilizes dual active firewalls (SPI and NAT) to prevent 
potential attacks from across the Internet.
* Maximum wireless signal rate derived from IEEE Standard 802.11a, 802.11g and Draft 802.11n specifications. Actual data throughput will vary. Network conditions and 
environmental factors, including volume of network traffic, building materials and construction, and network overhead, lower actual data throughput rate. Environmental 
conditions will adversely affect wireless signal range.
