This setting specifies how the router assigns IPv6 addresses to the devices on your home
network (the LAN).
10. (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.
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.
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.
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.
To change the MTU size:
1. Launch a web browser from a computer or wireless device that is connected to the
network.
2. Type http://www.routerlogin.net or http://www.routerlogin.com.
