Beta Asuswrt-Merlin 3004.388.10 Beta is now available

[RMerlin]

Asuswrt-Merlin 3004.388.10 Beta is now available for supported devices. The focus of this release is the merge of an updated GPL, and the backport of a few new features from 3006.102.

3004.388.10 (xx-xxx-2025)
  - NOTE: For developers, please note that the new default branch
          is now called "main" - it's what was previously the
          3006.102 branch.
          The "master" branch has been renamed "master-old", and
          is no longer actively used.  Due to how the 3006.102
          branch diverged, it was easier to do it this way than
          to fold back 3006.102 on top of master.
          3004.388 remains where 3004.388 models live.

  - NOTE: Due to numerous webui changes, it's recommended to
          force refresh the page after first login, or clear
          your browser cache.

  - NEW: Completely redesigned System Log -> Connections page.
           - You can now filter the list
           - You can set the page to auto-refresh itself
           - Public IP addresses can be looked up on
             WhatismyIPaddress.com
           - Local hostnames will be resolved and shown
           - Routed IPv6 connections will be shown

  - NEW: Added Control-D servers to DNS-over-TLS
         presets (dave14305)
  - UPDATED: Merged GPL 388_25523.
  - UPDATED: dropbear to 2025.88.
  - CHANGED: Setting DNS Director to "Router" will now always
             redirect to the router's own IP.  Previously it
             would redirect to the first DNS server configured
             on the DHCP page (which defaults to the router
             itself).
             If you need DNS Director to redirect to an IP
             configured in your DHCP settings, use a Custom DNS
             entry in DNS Director.  This makes it more consistant
             with what the name implies, and was also necessary
             for improved Guest Network support.
  - CHANGED: Replaced netstat-nat by a fork called netstat-nat-ng.
             This fork fixes a number of issues with IPv6 and
             field size.
  - CHANGED: Optimized performance when refreshing the Sysinfo
             page on a network with thousands of tracked
             connections.
  - CHANGED: Modified the Quick Internet Setup wizard so not
             to attempt downloading firmware updates from Asus
             (which would fail anyway).
  - CHANGED: Tools category renamed System Info.
  - CHANGED: Tools -> Other Settings were moved to new tabs
             (Administration -> Tweaks, and
             Traffic Analyzer -> Settings).
  - CHANGED: Moved "Redirect to asusrouter.com" to the new
             Tweaks tab, and moved "Enable JFFS Custom Scripts"
             to the Basic Config section on the System page.
  - FIXED: DNSDirector "Router" mode would not always work properly
           with IPv6 (now uses REDIRECT instead of DNAT, which was
           backported from iptables 1.4.19).
  - FIXED: Additionnal fix for the status frame missing from
           Network Map under certain hostnames.

Known issues:

• Cannot save settings on the Tweaks page (Javascript error from cstats leftovers)

So this is the one I need to upgrade my RT-AX88U Pro from 3004.388.8_4?

I wasn't ready for 3006...

No. Devices migrated to 3006 are no longer being supported by 3004.

ok, then I'll let 3006 mature a bit more, I remember reading some issues with Guest Network and IoT devices... I'm not in the mood to mess with that for now. And they say when it's not broken don't update. Mostly looking to update only for the security fixes.

3004.388.10_beta1 works for me on RT-AX86U. Basic configuration, I just flash, no reboot, just works for me...

 

[Untried3868]

3004.388.10 beta1 installed on my AXE-11000. Hard reset (WPS) after flashing firmware and removing node. Everything seems to be running well after re-adding node. No issues.

 

[crazyindianstranger]

Flashed over alpha 2, working fine on RT AX58U. No issues observed.

 

[Aarlin303]

Everything fine for my AXE-11000 with this

 

[geobernd]

Flashed yesterday on my RT-AX86U shortly after it was released.
Working 100% stable for me so far.

Thank you for all the hard work in keeping Asusmerlin going and thus making Asus Routers my #1 choice!

 

[Gar]

Works great, thanks. Power cycle to get Skynet working, reboot wouldn't do it.

 

[MacG32]

Everything's up and running nice and smooth. Thank you!

Enabling upnp on ax86u doesnt work manually port forwarding is fine.

 

[SomeWhereOverTheRainBow]

Enabling upnp on ax86u doesnt work manually port forwarding is fine.

Yeaa I don't see too much wrong with UPNP if there are restrictions, and a script notifies the admin when ever a port is open via email or some other notification method.

Agreed mate.

Hello everyone,
I am considering testing version 388.10 Beta on my AX88U.
Reading the changelog carefully, I saw that there had been changes to the DNS Director section.
I usually use the following configuration on version 388.9_2, which works perfectly well :

I am not including my smartphone, as it has a custom DNS configuration set up on the device itself.
If I don't add it to the “no redirection list,” it uses the router's DNS, which I don't want.

Can I use these same settings on the new version 388.10 ?

On the new firmware version, does the Router option still force clients to use the DNS provided by the router's DHCP server ?
(Or the router itself if it is not defined, as in my case where the DNS1 and DNS2 fields are empty)

Thank you for your clarification.

 

[jrichard326]

Dirty Flash from the stable release.No issues to report.

 

[ColinTaylor]

Can I use these same settings on the new version 388.10 ?

Yes. Because you don't have any IP addresses configured in LAN - DHCP Server > DNS Server 1 or DNS Server 2.

On the new firmware version, does the Router option still force clients to use the DNS provided by the router's DHCP server ?
(Or the router itself if it is not defined, as in my case where the DNS1 and DNS2 fields are empty)

The changelog says:

"Router" will now always redirect to the router's own IP.

Installed last night following a long and stable run with the latest production version. It took a solid 5 minutes for one of the 4 cores to finally settle down, yet has been stable since.

 

[Avrution]

I just flashed this on an AX88U and almost everything works fine. Only problem, I cannot change the options at the bottom of the Administration - Tweaks - Advanced Tweaks and Hacks section. After applying it will just sit there saying "Applying Settings..." infinitely.

As an aside, wasn't there supposed to be a way to disable the constant reaching out to dns.msftncsi.com? Since disabling the parts in nvram doesn't work anymore - I had 50k attempts in the past few weeks.
