The IPv6 page displays.
5.  In the Internet Connection T
 ype menu, select PPPoE.
The router automatically detects the information in the following fields\
:
• Router’s IPv6 Address on WAN. 
 This field shows the IPv6 address that is acquired 
for the router’s WAN (or Internet) interface. The number after the slash (/) is the 
length of the prefix, which is also indicated by the underline (_) und\
er the IPv6 
address. If no address is acquired, the field displays Not Available.
• Router’s IPv6 Address on LAN. 
 This field shows the IPv6 address that is acquired 
for the router’s LAN interface. The number after the slash (/) is the length of the prefix, 
which is also indicated by the underline (_) under the IPv6 address. I\
f no address is 
acquired, the field displays Not Available.
6.  In the Login field, enter the login information for the ISP connection.
This is usually the name that you use in your email address. For example\
, if your main  mail account is JerAB@ISP
 .com, you would enter JerAB in this field. Some ISPs (like 
Mindspring, Earthlink, and T-DSL) require that you use your full email address when you 
log in. If your ISP requires your full email address, enter it in this f\
ield.
7.  In the Password  field, enter the password for the ISP connection.
8.  In the Service Name field, enter a service name.
If your ISP did not provide a service name, leave this field blank.

Note:The default setting of the Connection Mode menu is Always On to 
provide a steady IPv6 connection. The DST router never terminates 
the connection. If the connection is terminated, for example, when the 
modem is turned off, the DST router attempts to reestablish the 
connection immediately after the PPPoE connection becomes 
available again.
9. Select an IPv6 Domain Name Server (DNS) Address radio button:
• Get Automatically from ISP. Your ISP uses DHCP to assign your DNS servers. Your 
ISP automatically assigns this address.
• Use These DNS Servers. If you know that your ISP requires specific servers, select 
this option. Enter the IP address of your ISP’s primary DNS server. If a secondary 
DNS server address is available, enter it also.
10. Select an IP Address Assignment radio button:
• Use DHCP Server. The DST router assigns IPv6 addresses to the devices on your 
home network (the LAN) through a DHCP server.This method passes more 
information to LAN devices, but some IPv6 systems might not support the DHCv6 
client function.
• Auto Config. This is the default setting.
11. To specify the interface ID for the IPv6 address of the DST routers LAN interface, select the 
Use This Interface ID check box and enter the interface ID.
If you do not specify an ID here, the DST router generates one automatically from its 
MAC address.
12. Click the Apply button.

Change the MTU Size
The maximum transmission unit (MTU) is the largest data packet a network device transmits. 
When one network device communicates across the Internet with another, the data packets 
travel through many devices along the way. If a device in the data path has a lower MTU 
setting than the other devices, the data packets must be split or “fragmented” to 
accommodate the device with the smallest MTU. 
The best MTU setting for NETGEAR equipment is often the default value. In some situations, 
changing the value fixes one problem but causes another. Leave the MTU unchanged unless 
one of these situations occurs:
•You experience problems connecting to your ISP or other Internet service, and the 
technical support of either the ISP or NETGEAR recommends changing the MTU setting. 
These web-based applications might require an MTU change:
-A secure website that does not open, or displays only part of a web page
-Yahoo email

Enable the Bridge or Add a VLAN Tag Group
Some devices, such as an IPTV, cannot work behind a router’s network address translation 
(NAT) or firewall. Based on what your Internet service provider (ISP) re\
quires, for the device 
to connect to the ISP’s network directly, you must enable the bridge between the device and 
the router’s Internet port or add new VLAN tag groups to the bridge. 
Enable the Bridge 
If your device, such as an IPTV, is connected to the DST router’s Ethernet port or WiFi 
network, you can enable the bridge so that the packets sent between the \
device and the DST 
router’s Internet port are not processed through the DST router’s network address translation 
(NAT).
To enable the bridge:
1. Launch a web browser from a computer or WiFi device that is connected to\
 the network.
2.  Enter  http://www
 .routerlogin.net.
A login window displays.
3.  Enter the DST router user name and password.
The user name is  admin. 
 The default password is password . The user name and 
password are case-sensitive.

to which the 
device is connected.
• If your device is connected to your DST router’

Add VLAN Tag Groups
You can add VLAN tag groups to the bridge and assign VLAN IDs and priorit\
y values to each  VLAN tag group.
If you add a VLAN tag group to the bridge, packets sent between the devi\
ce and the DST

 s Internet port are not processed through the router’s network address translation 
(NAT) or firewall.

6.   Optimize Performance
You can set up the DST router to optimize performance for applications such as Internet gaming, 
high-definition video streaming, and VoIP communication. By default, the DST router uses Wi-Fi 
Multimedia Quality of Service (WMM QoS).
This chapter contains the following sections:
•Use Dynamic QoS to Optimize Internet Traffic Management 
•Improve Network Connections With Universal Plug and Play 
•Wi-Fi Multimedia Quality of Service  
						

							Optimize Performance 69
 Nighthawk DST AC1900 DST Router and DST Adpater Model R7300DST
Use Dynamic QoS to Optimize Internet Traffic 
Management
Dynamic Quality of Service (QoS) helps improve your DST router’s Internet traffic 
management capabilities through better application and device identifica\
tion, bandwidth 
allocation, and traffic prioritization techniques. Dynamic QoS resolves traffic congestion when 
the Internet bandwidth is limited and different demands compete for bandwidth.
If your Internet download and upload speed is 250 Mbps or less and you l\
ike gaming and 
streaming video, then you can benefit from enabling Dynamic QoS.
Note:
If you use a gigabit Internet connection, or your Internet download and \
upload speed is 300 Mbps or faster, then you don’t need to use 
Dynamic QoS.

5. Select the  Enable Dynamic QoS check box.
6.  Specify your Internet bandwidth.
You must specify your Internet bandwidth so that Dynamic QoS can perform \
bandwidth  allocation and traf
 fic prioritization.
To allow Speedtest to detect your Internet bandwidth (recommended): a. For more accurate Speedtest results, make sure that no other devices are\
 accessing 
the Internet.
b.  Click the  Speed T
 est button.

A link to the Attached Devices page displays on the bottom. Click the link to view  bandwidth utilization. For more information, see View Devices Currently on the Network 
on page   195.
Enable or Disable the Automatic QoS Database Update
The DST router uses a QoS database of the most popular applications and \
services to 
implement Dynamic QoS. By default, the DST router automatically updates \
this database. 
You can turn off this feature and manually update the database.
