Firmware Upgrade New firmware versions are posted at www.linksys.com
and can be downloaded for free. If the Router already works well, there's no
need to download a newer firmware version, unless that version has a new fea-
ture that you want to use. (To learn about any new firmware with new features,
visit www.linksys.com.)
Note: By upgrading the Router's firmware, you may lose the Router's
configuration settings, so make sure you write down the Router's set-
tings before you upgrade its firmware.
To upgrade the Router's firmware:
1. Download the firmware upgrade file from www.linksys.com, and extract
the file using a file archive utility such as WinZip.
2. Click the Upgrade button.
3. On the Upgrade Firmware screen (see Figure 6-13), click the Browse but-
ton to find the firmware upgrade file you extracted.
4. Double-click the firmware upgrade file you extracted.
5. Click the Upgrade button, and follow the on-screen instructions.
Important: When you are upgrading the firmware, do NOT turn off
the Router, and do NOT press the Reset button.

Multicast Pass-Through IP Multicasting occurs when a single data transmis-
sion is sent to multiple recipients at the same time. Using the Multicast Pass-
Through feature, the Router allows IP multicast packets to be forwarded to the
appropriate computers. Keep the default setting, Enable, to support the feature,
or select Disable to disable it.
MAC Cloning You can clone the MAC address of your PC's network adapter
onto the Router.
A MAC address is a 12-digit code assigned to a unique piece of hardware for
identification. Some ISPs require that you register the MAC address of your
PC's network adapter, which was connected to your cable or DSL modem dur-
ing installation. To avoid calling your ISP and changing the MAC address that
is registered with the ISP, follow these instructions:
1. Select Enable.
2. Enter your adapter's MAC address in the MAC Address field.
3. To save your new settings, click the Apply button. To cancel your changes,
click the Cancel button. To get more information about the features, click
the Help button.
To disable MAC address cloning, keep the default setting, Disable.
If you do not know your adapter's MAC address, follow these instructions:
1. Click the Start button, and select Run.
2. Enter command in the field provided, and press the OK button.
3. At the command prompt, enter ipconfig /all. Then press the Enter key.
4. Write down your adapter's physical address; this is the adapter's MAC
address.
Remote Management This feature allows you to manage your Router from a
remote location, via the Internet. To disable this feature, keep the default set-
ting, Disable. To enable this feature, select Enable, and use the specified port
(default is 8080) on your PC to remotely manage the Router. You must also
change the Router's default password to one of your own, if you haven't
already. A unique password will increase security.
