AsusWrt-Merlin Firmware 3.0.0.4.374.42.0 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.

Fixes:

- NEW: Merged with Asus's 374_5656 GPL.
- NEW: Added Comodo Secure DNS to supported DNSFilter services
- FIXED: Download2 folder wasn't selectable anymore on the Media Server page.
- FIXED: Pass correct valid and preferred lifetime to radvd when using DHCPv6-PD (Patch by pinwing)
- FIXED: IPv6 connectivity could be lost after 1-2 hours due to the time shift caused by NTP at boot time (Patch by pinwing)
- FIXED: Various IPv6 connectivity issues related to services being (re)started at the wrong time, or twice. (Patch by pinwing)
- FIXED: Build system would sometime try to use the local system's header/libs - use a pkg-config wrapper to avoid this issue (Patch by ppuryear)
- FIXED: Erratic 5G led blinking behavior as the watchdog's software- based blinking was constantly writing to the wireless chip's registers for led control. (AC68)
- FIXED: LEDs weren't all turning back on when coming out of Stealth Mode (AC56)
- CHANGED: Make the router use dnsmasq for internal name resolution rather than directly using the WAN DNS.
- CHANGED: Upgraded OpenVPN to 2.3.4.
- CHANGED: Upgraded miniupnpd to 1.8.20140422 (PCP-related fixes)

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.
