Installation
Initial Flash
Prerequisites
- Download the asus_rt-ac88u-firmware.trx file from the asus-rt-ac88u folder.
- NOTE: You may optionally use the asus_rt-ac88u-firmware.trx file from the experimental_driver folder under the asus-rt-ac88u folder.
- See here for more info.
- Download and Install the ASUS Firmware Restoration Tool version 2.1.0.3 from the Asus Support Website (direct link)
- Optional: Download abnd Install the ASUS Device Discovery Tool version 1.4.8.3 to discover the IP of your router if unknown (direct link)
Procedure
NOTE: The ASUS Firmware Restoration Tool is the preferred / recommended method for initial flash. The other procedures are provided as alternatives.
Using The ASUS Firmware Restoration Tool
- Steps derived from How to use Rescue Mode (Firmware Restoration)? on the Asus website.
Using the ASUS Mini CFE web server
- Similar to above, but using a web browser instead of the ASUS Firmware Restoration Tool
Manually via AsusWRT WebUI
Upgrading DD-WRT
Prerequisites
- Download the asus_rt-ac88u-firmware.trx file from the asus-rt-ac88u folder.
- NOTE: You may optionally use the asus_rt-ac88u-firmware.trx file from the experimental_driver folder under the asus-rt-ac88u folder.
- See here for more info.
Procedure
- Set a static IP of 192.168.1.5 (or similar IP address within your configured subnet) on the PC you are using to upgrade firmware.
- Open a browser to http://192.168.1.1 (or whatever you've set your router IP to).
- Go to Administration -> Firmware Upgrade tab.
- Click on "Browse", locate and select previously downloaded asus_rt-ac88u-firmware.trx file.
- Click on the "Upgrade" button.
- Please allow up to 10 minutes for the firmware upgrade process to complete. Do not disconnect your PC or power cycle your router during this process.
- Once the router has rebooted, click on "Continue" (if the Setup -> Basic Setup tab has not returned automatically) or point
your browser to http://192.168.1.1 if you end up with a "Connection reset or other navigation error page in your browser. - At this point, check in the webUI that the version of DD-WRT is the version you intended to upgrade to.
- Please report in the Broadcom sub-forum successful flash reports or any other issues in the appropriate build thread for your firmware version.
Recovery
- Use the Asus Firmware Restoration tool or mini CFE webserver method to recover a bricked device using either AsusWRT or a known good DD-WRT firmware image.
