Orbi Quad-Band Mesh WiFi 6E System This setting specifies how the router assigns IPv6 addresses to the devices on your home network. 8. (Optional) Select the Enable RIPng check box. This selection enables RIP Next Generation (RIPng) on IPv6 Internet connections. RIPng is an extension of Routing Information Protocol (RIP) that supports IPv6. 9. (Optional) Select the Use This Interface ID check box and specify the interface ID that you want 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. 10. (Optional) To set a specific MTU size for an IPv6 6rd tunnel Internet connection, specify the MTU size in the MTU Size (in bytes) field. 11. 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. For example, if a secure website does not open, or displays only part of a web page, you might need to change the MTU. • 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. Note: An incorrect MTU setting can cause Internet communication problems. For example, you might not be able to access certain websites, frames within websites, secure login pages, or FTP or POP servers. Specify Your Internet Settings 44 User Manual

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.

For example, if a secure website does not open, or displays only part of a web page,

you might need to change the MTU.

•

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.

Note:

An incorrect MTU setting can cause Internet communication problems. For

example, you might not be able to access certain websites, frames within websites,

secure login pages, or FTP or POP servers.
