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.
- Set a static IP of 192.168.10 with subnet mask of /24 (255.255.255.0) on the PC you are using to flash the router.
- Connect PC to one of the router's LAN ports with an ethernet cable.
- Place the router in Rescue Mode:
- Unplug the router's power cord (you may try waiting a minute if it doesn't go into recovery mode).
- Press and hold the reset button (there is an ongoing discussion on whether it's the WPS or reset button, try both).
- Keep long pressing the Reset button and plug the cord to DC IN at the same time.
- Notice: Please DO NOT release the Reset button until the Rescue Mode is enabled.
- The router turns to the Rescue mode when you see the power indicator light is slowly flashing.
- Click Start > ASUS Utility > Firmware Restoration
- Click Browse and choose the asus_rt-ac88u-firmware.trx file you downloaded previously.
- After choosing the file, click Open.
- Click Upload and then wait for around 1 min (or more, see indication of completion).
- Notice: Before uploading the file, please make sure that you already turn your router to the Rescue Mode.
- Otherwise you can't use Firmware Restoration to do the firmware update.
- Steady power light indicates the setting procedure of Rescue Mode has been completed successfully.
- Wait for the router to reboot and then click Close.
- Return your PC to default auto-dhcp settings.
- Open a browser and go to http://192.168.1.1 where you should be greeted by the password change page of the DD-WRT webUI.
- Set username and/or password, then continue configuring to your preferences.
- NOTE: You will need to enter user/pass to navigate away from the information page after setting them.
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 192.168.1.10 (or similar IP address within your configured subnet) on the PC you are using to upgrade firmware.
- Connect PC to one of the router's LAN ports with an ethernet cable.
- 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.
