Change The Mtu Size - GEEK SQUAD NIGHTHAWK DSTL User Manual

Nighthawk DST AC1900 DST Router and DST Adpater Model R7300DST
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 router's 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.
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 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
