Instant Wireless® Series

Upgrade Firmware 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.) Loading new firmware onto the Router does not always enhance the speed or the quality of your connection.

Note: By upgrading the Router’s firmware, you may lose the Router’s configuration settings.

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.Select the Help tab, if you haven’t already (see Figure 6-17).

3.Click Upgrade Firmware to display a new window, shown in Figure 6-18.

4.Click the Browse... button to find the firmware upgrade file you extracted.

5.Double-click the firmware upgrade file you extracted.

6.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.
