AsusWrt-Merlin Firmware 380.65 Beta 1 for RT-N66U (VER.B1) 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: Merged with Asus GPL 380_4180 (and fixed its broken Network Tools/Connections/etc... pages)
- NEW: Upgraded to OpenVPN 2.4.0, and implemented support for many of its new features: GCM ciphers, LZ4 compression, tls-crypt (uses the Static Key field), Cipher negotiation (NCP), with (optional) fallback to legacy "cipher" parameter when an OpenVPN 2.3 client connects to the router's 2.4 server. Please refer to the OpenVPN 2.4 documentation for more info on these new features. You will be warned if any server setting would generate an exportable ovpn file that would be incompatible with older clients. Existing client config shouldn't need to be changed, unless you modify the router's server configuration.
- NEW: Upgraded Busybox to 1.25.1 (patch by theMIROn)
- NEW: Added the following Busybox applets: ntpd, time, uniq, xargs and getopt, for feature parity with John's fork.
- NEW: Option on Media Server page to enable minidlna's built-in status web page. Default URL is http://router.asus.com:8200 .
- NEW: Support for Vodafone R226 USB LTE (patch by Gernot Pansy)
- NEW: New "update-notification" user script, that gets run when a scheduled firmware check detects a new version is available.
- CHANGED: Removed support for all RC ciphers on OpenVPN. DES is staying for now, but should still be avoided whenever possible.
- CHANGED: Updated Tor to 0.2.9.8 (patch by blackfuel)
- CHANGED: Updated nano to 2.7.4.
- CHANGED: hosts file will now give a higher priority to the user-configured hostname for the router ahead of hardcoded ones (like router.asus.com).
- CHANGED: Create a system log entry if new firmware is available.
- FIXED: Invalid DUID used when requesting an IPv6 prefix for some of the newer router models, which would prevent them from getting working IPv6 (Asus bug)
- FIXED: Network Service Firewall rules not applied under certain configurations
- FIXED: Port triggering wasn't working if traffic had been whitelisted by Network Service Firewall
- FIXED: Avahi wasn't rejecting connections from secondary WAN interface
- FIXED: Sorting clients by connection time would incorrectly treat 10 hours as longer than 9 hours, as it was handling it as a string (Asus bug)
- FIXED: Exported ovpn client file wouldn't use the user-configured hostname when using DDNS custom mode.
- FIXED: Exported OpenVPN client config didn't work when using static key authentication.
- FIXED: Exported OpenVPN client config wasn't editable with Notepad, the default editor used by Windows's OpenVPN GUI.
- FIXED: OpenVPN was killed too quickly on disconnection, causing issues when using explicit-exit-notify (patch by john9527)
- FIXED: OpenVPN client/server instances weren't properly restarted on a WAN restart (patch by john9527)
- FIXED: Some models (N66/Ac66/AC5300) would reboot 3 times if one of the radios was found disabled by the user while booting (Asus bug).
 

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.
