Hello and sorry for my poor English!
I have also problems with set a DNS Server in the Web-Interface. I run an ASUS RT-AC66U with the RT-AC66U_374.43_39E3j9527 Firmware.
If I set in the tab "WAN settings" the checkbox "Connect to DNS Server automatically" to No and enter the IP for my Raspberry Pi in the field for the DNS-Server 1 the interface shows me a window with "Done" (or something like that - I see it in German) and it stays constant in the browser tab without reload.
If I reload the tab by hand, the settings I made are not set. I reboot the router and start again - without success. So I cannot set a specify DNS-Server im my router.
This is only in the Internet Explorer (Windows 7). In Firefox I become not a connection to the Router-Interface! Firefox produce a high CPU load and cannot connect.
Do anybody know what could I do?

THANK you!

How to install the firmware at Merlin 380.70, when installing over, it gives an error: Invalid Firmware Upload To ensure a better firmware quality. It is not compatible with the third party firmware. Please check our official websites for the certified firmware.
From the first post:

Installation Notes
  • Firmware is now packaged as a zip file (consistent with Merlin firmware releases). Remember to extract the .trx file prior to updating the firmware. An sha256sum file is included in the zip file to validate the firmware.
  • For supported routers currently running ASUS firmware 380.3000 or above, or Merlin 380.60 or above, you cannot load this fork using the built in firmware update web interface. You must use the ASUS Firmware Restoration Tool from the ASUS support website or the built in CFE Mini-Web Server to install this fork firmware. You must always perform a factory default reset following the firmware update when moving from ASUS OEM or Merlin firmware above level 374 regardless if you updated via the web interface or Restoration Tool.
  • When using the ASUS Firmware Restoration Tool or CFE Mini-Web Server to install this fork firmware on MIPS based routers (N16, N66 or AC66 non_B1) the upgrade process can take from 40 minutes to 1 hour. Please be patient and do not interrupt the process.
  • Currently, two build streams are maintained.
    • The 'E' Builds are the recommended builds and contain the latest wireless drivers and related fixes, including the fixes for the KRACK exploit on all supported models except the N16 (ASUS never released a KRACK fix for the N16). The 'E' Builds for ARM routers also contain the latest ARM SDK providing support for the newer rev level AC68U and it's variations.
    • The 'L' Builds contain the original wireless drivers (2014 release) and DO NOT address the KRACK exploit, and for ARM routers DO NOT contain the latest SDK providing support for the latest AC68U rev levels. In addition, some fixes dependent on either the latest wireless drivers or latest ARM SDK may not be included in the 'L' builds. Please review the release notes/Changelog for further information.
  • If you are updating an AC56U or AC68U running a fork version V26 or earlier, a factory reset is recommended following the firmware update to V27 or later. You may also need to reformat and restore JFFS due to updates for compatibility with the Merlin releases. Other fork users running an N16, N66U or AC66 can update to the 'E' Build as normal without a factory reset.
  • Please review '@UpgradeMatrix.txt' in the download directory, which describes the upgrade options for all the supported routers. Included are the requirements for a Factory Default Reset or reformat of JFFS.
  • Users are reminded to have a jffs backup. For users with MIPS based routers, changes in the code image size may affect the jffs space. For users of ARM based routers, changes in the jffs partitioning may also affect the jffs allocations. If you are having jffs script errors or cannot access jffs after loading the firmware, please reformat jffs from the Administration page and restore your jffs backup.

What does the System Log show during the time after you hit Apply button? It should show the WAN interface restarting, and possibly any errors. You might also try to open your browser console (F12) and look for Javascript errors if nothing appears in System Log. Also make sure no AdBlockers or password managers are interfering with the router GUI pages.

Thank you Dave for your suggestions! What you mean with system log? From Windows, or is such included in the router firmware?
The IE browser console shows me one error:
SCRIPT429: Automatisierungsserver kann Objekt nicht erstellen.
Datei: detect.js, Zeile: 24, Spalte: 1

In Firefox I have not tried again.

Yes, I have read the first post and I have installed the firmware fork (long ago) with the ASUS firmware restoration tool.

The syslog page for the time I tried to set the DNS Server looks:

I'm not shure what the exact problem is.

After flashing, did you do a full reset to factory defaults afterward?

The M&M Config guide in my signature below may be helpful to you. Also, you may need to use the more thorough 'Nuclear Reset' link via the same link to ensure your router and network are fully reset and using all the features the new firmware offers. :)

I take from the system log that you are connecting to the router over https port 8443. Will you get the same behavior if you use http over port 80?

I’m not familiar with your ISP connection type to comment on those log entries.

I think the references to the first post were for another poster asking how to install the fork firmware, not you. Easy to misunderstand without quoting the correct post.

Hello everyone,
I have a problem where my router at random times becomes inaccessible and all devices become unreachable, but the router is still on, restarting it solves the problem.
Another problem which might be related, when my pc wakes up from sleep it causes the network to freeze, restarting the pc unfreezes the network.
Now I never use the sleep option, but the first problem still happens even when the pc is powered off.
I'm on the latest E version on an RTN66U, there is nothing in the system log from before the restart, I tried factory reset.

Any help would be appreciated.
Thanks for the awesome firmware.

@Quietsy Do you have any user scripts or custom config files active on your router, e.g. ad-blocking? If so disable all of those and go back to a "basic" setup to determine whether they are the cause of the problem.

Another common problem with the RT-N66U (due to its age) is that the power adapter starts to fail. Some people have reported fixing their "intermittent problems" be replacing it with a new one.

I second this. I have an RT-68U that was showing intermittent problems with wifi dropouts and occasional freezing. Tried all troubleshooting steps with no success. Replacing the power supply solved all the issues with that router.

I suspect he's taking some "personal time" after the death of his father. I expect he'll be back when he's ready.
If not, perhaps someone else might take over the project, someone with the necessary skills. I probably shouldn't suggest it since I have no such skills and don't know what it entails.

Only a thought. I do hope he returns when the time is right.

Replacing John won't be easy. Dude has mad skillz, as the youngins say. But thanks to him my router is still supported and working well.

My RT-N66U has been running nicely for years, thanks to John's great work. But I finally thought I'd try to switch on IPv6. Not completely straightforward ...

I'm on BT in the UK. The settings that work seem to be mostly simple or default:

Connection Type: Native
Interface: PPP
DHCP-PD: enable
MTU: 1280​

I changed these ones:

LAN Prefix Length: 56
Release addresses on exit: No​

though I'm not sure if the release one is needed. However, the thing I can't work out is this:

Prefix delegation requires address request

If I set it to Yes, then I get IPv6 working but my log fills up with these messages - about 1 a second:

dhcp6c: dhcp6c state change detected SOLICIT

Apart from the log messages, everything else seems to be working. My router doesn't get a global WAN IPv6 address but apparently BT don't provide one anyway.

If I set it to No then the log messages stop but I lose the IPv6 Gateway and IPv6 stops working.

Anyone had this and/or found a fix?

Thanks!

Merlin original, Merlin LTE L and Merlin LTE E have three different Wi-Fi drivers, so you have to find out for yourself.
