• 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.

• Use DHCP Server. This method passes more information to LAN devices but
some IPv6 systems might not support the DHCPv6 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).
11. (Optional) Select the Use This Interface ID check box and specify the interface ID
to be used for the IPv6 address of the router's LAN interface.
If you do not specify an ID here, the router generates one automatically from its MAC
address.
12. Click the Apply button.
Your settings are saved.

Manage the MTU Size

The maximum transmission unit (MTU) is the largest data packet a network device
transmits.

MTU Concepts

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 maximum transmission unit (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
