Simultaneous Networks  For more wireless bandwidth, the router can create two simultaneous yet separate Wireless-N networks, one using the 5 GHz radio frequency band and one using the 2 .4 GHz band . This allows you to isolate higher-priority traffic, such as online gaming, Voice over Internet Protocol (VoIP) calls, and video streaming .   For example, in this diagram (“Simultaneous Networks Diagram” on page 11), the 2 .4 GHz wireless network is represented by green waves between the router and the office devices, the wireless printer and notebook . The 5 GHz wireless network is represented by the blue waves between the router and the living room devices, the gaming console and media player .   Choose which computers and other wireless devices should join which network . Wireless-N devices support both the 5 GHz and 2 .4 GHz bands, so they can join either network . Wireless-G and Wireless-B devices support only the 2 .4 GHz band, so they should join the 2 .4 GHz network . Wireless-A devices support only the 5 GHz band, so they should join the 5 GHz network .   For the 5 GHz network, configure all computers and other wireless devices with the same 5 GHz Network Name and wireless security settings . For the 2 .4   GHz network, configure all computers and other wireless devices with the same 2 .4 GHz Network Name and wireless security settings .   NOTE: You should use the same Network Name for both your 5 GHz and 2 .4 GHz wireless networks; this allows seamless roaming by dual-band Wireless-N client devices .   You can use Wi-Fi Protected Setup to set up both networks, or you can manually configure the router . Wi-Fi Protected Setup is a feature that makes it easy to set up your wireless network .

Applications and Gaming > QoS  Quality of Service (QoS) is a method that assigns priority to specific types of network traffic, which often are demanding, real-time applications, such as online gaming, VoIP calls, video streaming, and videoconferencing . QoS can mark packets to designate different levels of priority, so it helps to ensure optimal performance for the most important, real-time applications .   QoS is only applied to traffic streams that are uploaded to the Internet . QoS cannot be guaranteed after the traffic streams reach the Internet . Chapter 2: Advanced Configuration    Low . Depending on the application, a few attempts may be needed to set the appropriate bandwidth priority .  Enabled/Disabled To use the QoS policies you set, select Enabled . Otherwise, keep the default, Disabled .  Upstream Bandwidth  The Upstream Bandwidth feature sets the maximum outgoing bandwidth that applications can use . The default, Auto, allows the router to set the maximum . The router sets speeds that are multiples of 512 Kbps .
