Manage 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.

Use These DNS Servers If you know that your ISP does not automatically transmit DNS addresses
to the modem router during login, select this option and enter the IP
address of your ISP primary DNS server. If a secondary DNS server
address is available, enter it also.
NAT (Network Address Translation)
NAT allows computers on your home network to share the modem router Internet connection. NAT is
enabled by default because it is needed in most situations. Select the NAT settings:
• Enable. NAT is enabled. This is the default setting.
