ASUS RT-AC3100 AsusWrt-Merlin Firmware 384.14 Beta 3

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: Implement option to prevent Firefox's automatic usage of DoH. By default, this will only apply if you have DNSPrivacy enabled, or if you have DNSFilter enabled with a global filter, to ensure that Firefox will not bypass either of these. You can also have this override applied all the time, or completely disable it.
- NEW: Added "split" busybox applet.
- NEW: Added IPv6 support to Network Analysis webui
- NOTE: You might need to reconfigure your device hostname on the LAN -> LAN IP page due to a GPL-level change (exclusing the RT-AX88U)
- UPDATED: RT-AX88U to GPL 384_6436 (with Let's Encrypt fixes backported from 384_81351)
- UPDATED: RT-AC68U, RT-AC86U to GPL 384_81351
- UPDATED: RT-AC88U, RT-AC3100 to GPL 384_81351 and binary blobs from 384_81116
- UPDATED: RT-AC5300 to GPL 384_81351 and binary blobs from 384_81219.
- NOTE: This release is not available on the RT-AC87U and RT-AC3200 due to the lack of updated compatible components from Asus.
- UPDATED: miniupnpd 20190824
- UPDATED: dnsmasq 2.80-95-g1aef66b (themiron)
- UPDATED: OpenSSL 1.0.2 to 1.0.2t (themiron)

- CHANGED: Made webui SSL certificate generation compliant with IOS 13 and MacOS 10.15 new requirements.
- CHANGED: Rewrote the faketc script used to inject Codel into Adaptive QoS as a C program for improved performance.
- CHANGED: Moved /usr/bin/ip to /usr/sbin/ip on the RT-AC86U and RT-AX88U to match other models.
- CHANGED: IPv6 firewall now accepts empty values for local IP (which means any local IP).
- FIXED: Webui wouldn't notify when running dangerously low on free nvram (feature was lost at some point in the past)
- FIXED: Non-working link to YandexDNS on the webui for Russian models.
- FIXED: Backported various httpd fixes to RT-AX88 from other models.
- FIXED: Custom clientlist would be wiped if stopping an OpenVPN server instance.
- FIXED: Incorrect detection of EUI64 addresses on the IPv6 firewall (would prevent using ::/0 for instance).
- FIXED: EUI64 support missing while in Load Balancing or using Multicast IPTV.
- FIXED: Asus DDNS failing to update due to an invalid certificate on Asus's server.
- FIXED: Let's Encrypt support would sometime fail when using Asus DDNS (fixed DNS publishing of validation record) (in addition to general failure fixed by GPL 81351)
- FIXED: IPv6 neighbour solicitation drop toggle not working for some models
- FIXED: openvpn-event scripts would be executed even if custom scripts were globally disabled

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.
