AsusWrt-Merlin Firmware 380.64.0 for RT-N66W 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:

- NEW: New firmware availability notification. The router will notify you if a new firmware is available, and will also let you view the changelog before sending you to the download page (the update process remains manual). Note that the automated check will only report new final releases. The Check button on the Firmware Upgrade will immediately check for final releases or beta (if you select that option), but not both at the same time.
- NEW: Added iptables MASK support on MIPS kernel (patch by john9527)
- NEW: Webui warning shown in the notification area if running low on free nvram.
- CHANGED: Updated nano to 2.7.1.
- CHANGED: Updated OpenVPN to 2.3.14.
- CHANGED: Updated curl to 7.51.0, resolving numerous security and stability issues.
- CHANGED: Tor clients will now route other TCP ports than just 80/443, and drop UDP and ICMP traffic (patch by blackfuel)
- CHANGED: QoS Stats info will automatically refresh every 3 seconds (user-configurable)
- CHANGED: IPTraffic charts now show sorted slices, so the clients with the least traffic will get grouped under "Others" if truncating the list of shown clients.
- CHANGED: Enabled IPv6 support in curl.
- CHANGED: Improved webui performance, by caching large static Javascript files such as jquery, and increased cache life from 5 mins to 1 hour.
- CHANGED: No longer include Download Master packages in the firmware for those models that still included them, reducing firmware size by a few megabytes. Those were always outdated, the router will download the latest versions from Asus's servers at install time.
- CHANGED: Improved webui protection against CSS/XSS attacks (backport from GPL 4164)
- FIXED: Web server crash if importing an ovpn file with an invalid key or certificate (Asus bug)
- FIXED: App icon at the top wouldn't work on Firefox, generating a Javascript error (Asus bug)
- FIXED: Firefox would sometime fail to display the client list, reporting a JSON parsing error in the console.
- FIXED: HMAC setting not properly set when importing an ovpn file for a config based on TLS authentication mode. (backport from GPL 4164)

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.
