Specify Your Internet Settings
37
N750 WiFi Router
Note: The default setting of the Connection Mode list is Always On to
provide a steady IPv6 connection. The router never terminates the
connection. If the connection is terminated, for example, when the
modem is turned off, the router attempts to reestablish the connection
immediately after the PPPoE connection becomes available again.
10. To specify domain name server addresses, select the Use These DNS Servers radio button
and complete the Primary DNS and Secondary DNS fields.
11. Select an IP Address Assignment radio button:
• Use 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.
This setting specifies how the router assigns IPv6 addresses to the devices on your home
network (the LAN).
12. To specify the interface ID to be used for the IPv6 address of the router’s LAN interface,
select the Use This Interface ID check box.
If you do not specify an ID here, the router generates one automatically from its MAC
address.
13. Click the Apply button.
Your settings are saved.
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 uses 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
- MSN portal
- America Online’s DSL service
• You use VPN and experience severe performance problems.
• You used a program to optimize MTU for performance reasons and now you are
experiencing connectivity or performance problems.
