5.2 Firmware Restoration

Firmware Restoration is used on an ASUS Wireless Router that
failed during its rmware upgrading process. It uploads the
rmware that you specify. The process takes about three to four
minutes.
To launch the rescue mode and use the Firmware Restoration
utility:
1. Unplug the wireless router from the power source.
2. Hold the Reset button at the rear panel and simultaneously
replug the wireless router into the power source. Release the
Reset button when the Power LED at the front panel ashes
slowly, which indicates that the wireless router is in the rescue
mode.
3. Set a static IP on your computer and use the following to set up
your TCP/IP settings:
IP address: 192.168.1.x
Subnet mask: 255.255.255.0
4. From your computers desktop, click
Start > All Programs > ASUS Utility RT-AC66U Wireless
Router > Firmware Restoration.
IMPORTANT: Launch the rescue mode on the router before using the
Firmware Restoration utility.
NOTE: This feature is not supported on MAC OS.
