ASUS RT-AC66U rev. B1 AsusWrt-Merlin Firmware 380.69.0 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: Added option to disable the Asus NAT tunnel service under Other Settings -> Tweak. Not quite sure what this partly closed source service is for, but it eats a fair amount of CPU and RAM (backport from 382).
- CHANGED: Updated odhcp6c to be in sync with upstream
- CHANGED: Updated odhcp6c to be in sync with upstream (patch by theMIRon)
- CHANGED: Updated libogg to 1.3.3 and libvorbis to 1.3.5.
- CHANGED: Updated wget to 1.19.2 (fixing connectivity to some TLS 1.2 servers)
- CHANGED: Updated RT-N66U and RT-AC66U SDK to GPL 380_8120's (fixing KRACK in repeater/bridge mode)
- CHANGED: Updated openssl to 1.0.2n.
- CHANGED: Updated tor to 0.2.9.14.
- FIXED: allow IA_NA mode downgrade with forced IA_PD (for ISPs with broken IPv6 support) (patch by theMIRon)
- FIXED: Trend Micro signature check might randomly fail the RSA validation.
- FIXED: Security issues CVE-2017-15275, CVE-2017-12163 and CVE-2017-12150 (backported to Samba 3.6 and 3.5)
- FIXED: Httpd crash when accessing certain webui pages with no connected Ethernet clients
- FIXED: DNSFILTER rules would have priority over OPENVPN Client rules (when client has DNS set to Exclusive mode).
- FIXED: traffic routing from the router itself would fail when restarting the firewall while using an ovpn client with policy rules in effect.
 

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.
