AsusWrt-Merlin Firmware 3.0.0.4.378.56.2 for RT-AC68U Description

The AsusWrt-Merlin firmware was developed with the primary goal of boosting the original ASUS firmware, fix bugs and also add new improvements. This package includes a customized firmware targeted at ASUS routers that brings various changes without modifying the interface of the original firmware.

Changes:

- CHANGED: Reverted the memory buffering optimization for ARM devices, as people keep panicking over the lower amount of free RAM. You can manually re-enable the optimization by setting "drop_caches=0" in nvram.
- CHANGED: Allow using a port < 1024 for http(s) webui interface.
- FIXED: EMF wasn't working on AC56/AC68/AC87.
- FIXED: Couldn't connect to ISPs using VLANs (RT-AC87U)
- FIXED: Editing Port Forward entry with ellipsis in the description or the port range would still edit the shortened version instead of the full content.
- FIXED: Debug log from mDNSNetMonitor could gradually fill up RAM- disabled it.
- FIXED: Router crash if pasting SSH key > 2047 characters.
- FIXED: Editing an entry on the networkmap would clear the hostname if entry existed in the DHCP static list.
- FIXED: OpenVPN server in secret key mode would fail to start.
- FIXED: Couldn't add entries to the MAC Filter list of Guest Networks (reverted our previous implementation which conflicted with Asus's new one).
- FIXED: NTP failing to refresh for some cases. Implemented temporary workaround.
- FIXED: Some services not properly starting at boot time (like Parental Control or Tor)

Installation Notes:

- This custom firmware can be applied like any regular update.
- You should not need to reset to factory defaults.
- You can revert back to an original ASUS firmware at any time.
- Do not load a saved copy of your settings.

About Router Firmware:

Before you consider downloading this firmware, go to the system information page of the router and make sure that the currently installed version isn’t either newer or matching this release.

Due to the large variety of router models and different methods for upgrading the device, it is highly recommended that you read and, above all, understand the installation steps before you apply the new firmware, even if you are a power user.

In theory, these steps shouldn’t be much of a hassle for anyone, because manufacturers try to make them as easy as possible, even if they don’t always succeed. Basically, you must upload the new firmware to the router through its administration page and allow it to upgrade.

If you install a new version, you can expect increased security levels, different vulnerability issues to be resolved, improved overall performance and transfer speeds, enhanced compatibility with other devices, added support for newly developed technologies, as well as several other changes.

If you’re looking for certain safety measures, remember that it would be best if you perform the upload using an Ethernet cable rather than a wireless connection, which can be interrupted easily. Also, make sure you don’t power off the router or use its buttons during the installation, if you wish avoid any malfunctions.

If this firmware meets your current needs, get the desired version and apply it to your router unit; if not, check with our website as often as possible so that you don’t miss the update that will improve your device.

  It is highly recommended to always use the most recent driver version available.

Try to set a system restore point before installing a device driver. This will help if you installed an incorrect or mismatched driver. Problems can arise when your hardware device is too old or not supported any longer.
