AsusWrt-Merlin Firmware 3.0.0.4.378.51 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.

IMPORTANT:

- You must do a factory default reset, and manually configure your setting if coming from a version older than 378.50. Failure to do so can lead to various issues with wifi, OpenVPN, and the new AC68U bootloader.
- Please read this changelog, especially the changes related to jffs, user scripts/config and OpenVPN in the previous 378.50 betas.

Notice for RT-N16 Owners:

- The RT-N16 is no longer officially supported. The increased number of separate router platforms is becoming too much of a burden for one single developer, as some features must be implemented 2-3 separate times for different architectures.
- The RT-N16 support will remain in the source code, so other developers can still compile their own builds, and possibly take over for supporting this older platform. However, no new features will be implemented, and it will no longer get tested. I still welcome external contributions if someone else wants to take care of testing and providing fixes to new issues.

Changes:

- NEW: Added support for the RT-AC3200.
- NEW: ARM support for Entware, using Zyxmon's Qnapware repository.
- NEW: Re-designed Wireless Log page displaying connected wireless clients. The new page uses Ajax to automatically update itself at a user-selected frequency, for near realtime monitoring of your connected wifi clients.
- NEW: NAT loopback can now be chosen between Disable, Asus's original, and Merlin's own (based on Phuzi0n's original DD-WRT design). The option can be found on the Firewall page.
- CHANGED: Reverted RT-AC66U driver to previous version as some users were experiencing stability issues with the 3754 version.
- CHANGED: Updated p910nd to 0.97 to resolve incomplete print jobs (patch by stsichler)
- CHANGED: Updated Samba to 3.6.25
- CHANGED: The Entware setup scripts will now backup any existing installation rather than remove it (patch by TeHashX)
- CHANGED: Re-implemented our original NAT loopback code, with attempts at reconfiguring it whenever the DPI engine is restarted. This is still experimental, as most of the DPI engine is closed source, so unsure if the loopback gets re-enabled in every regular DPI restart scenarios.
- CHANGED: Disabled the offline default error page. Clear your offline content in your browser to fully get rid of it.
- CHANGED: Removed security warnings if FTP/Samba are configured to allow unauthenticated users.
- FIXED: Issues when connecting with Russian ISPs relying on DHCP+VPN (such as Beeline)
- FIXED: When enabling WAN access to webui, the router would always forward both http and https ports regardless of if either of these were disabled.
- FIXED: Shared printers over LPRng would sometime fail to completely print the last page (patch by stsichler)
- FIXED: CVE-2015-0240 security issue in Samba 3.5.8 (used by AiCloud). The main Samba daemon was patched by the update to 3.6.25.

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.

  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.
