AsusWrt-Merlin Firmware 378.56 Beta 1 for RT-AC66W 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.

- NEW: Added support for the RT-AC88U.
- NEW: Support for Russian ISP Telenet (code by theMIROn)
- NEW: ipset support in dnsmasq (patch by ryzhov_al)

- CHANGED: Improvements to VPN Status page
- CHANGED: Connection failure reason shown on the OpenVPN client configuration page.
- FIXED: Router crash when an invalid or corrupted DH parameter is used on an OpenVPN server configuration.

- FIXED: Resource leaks in ez-ipupdate if an update failed
- FIXED: Networked printers coming out of sleep everytime network map queried their LPR service
- FIXED: Resource leak in network map when scanning for printer servers
- REMOVED: Regulation mode setting on Wireless -> Professional. This can't be adjusted anymore, as it was moved to a closed source component.

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.
