ASUS RT-AC86U AsusWrt-Merlin Firmware 382.2 Beta 3 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.

Important Notes:

- Due to various issues with GPL 382_18991, the 382.2 release is being dropped, and work is moving on to the next version. 382.2 beta releases remain available for those who still wish to use it (especially RT-AC56U users for whom there is no ETA as to when Asus will release the next GPL for that particular model.) Known issues include lack of PPPoE HW acceleration and Adaptive QoS sometimes failing to start at boot among others.
- The official IRC channel has moved to Freenode (#asuswrt).

Changes:

- NEW: Merged with GPL 382_18991. Most notable changes (will vary between models): Added IPSec VPN server, Added IFTTT and Alexa support, Let's Encrypt support (DDNS page), Better support for some longer settings (RT-AC86U)
- NEW: Merged HND SDK + binary components from 382_18848 (RT-AC86U)
- NEW: Added IPSec VPN status on the VPNStatus page.
- NEW: Added support for RT-AC56U and RT-AC68U (and all of its variants)
- NEW: Enabled support for Let's Encrypt on RT-AC56U and RT-AC68U (in addition to RT-AC88U/3100)
- CHANGED: Moved HTTPS cert management to the DDNS page (where Asus has put theirs, as Let's Encrypt is tied to the DDNS configuration)
- CHANGED: Updated openssl to 1.0.2n.
- CHANGED: Updated tor to 0.2.9.14.
- CHANGED: Updated nano to 2.9.1.
- CHANGED: Updated curl to 7.57.0.
- CHANGED: Increased max length for OpenVPN custom settings from 170 to 510 characters on RT-AC86U.
- CHANGED: Updated miniupnod to Github snapshot 20171212.
- CHANGED: OpenVPN firewall rules are now processed after the various security chains (access restriction, network service firewall, etc...), ensuring OVPN traffic no longer bypasses them.
- FIXED: httpd crash on certain web pages if there are no Ethernet clients connected
- 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.
- FIXED: Dashes were rejected when used in an OpenVPN policy client description.
- REMOVED: Removed option to select between active and passive scan mode for a site survey (that code is now closed source and therefore that option can no longer be implemented).
 

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.
