When using this installer, is there anyway to set certain devices to not use NextDNS and just use the router's DNS? There are devices that don't play well with NextDNS relatively high latency since its not consistent in picking your closest node. I would like those devices to just use other DNS instead.

It should always pick the closest one. Contact us on support chat if it does not.

Dns filter on the router. But it is in the routers gui and not the installer.
I have contacted support chat before. The issue improved for a while, but right now it became worse and seems to have connected to an even further node than usual, based on the ping page.
I am just trying to to see if I can set some devices to just use other DNS. Most of the users in the house don't mind the random latency jumps, but for others that do mind, or for those IOT devices that seem to respond poorly, I would like to just use other DNS in the meantime while wating for it to be fixed. It's faster to just do so instead of troubleshooting with support which I understand will take time.
This doesn't seem to work if the installer is used. I tried using dnsfilter to other DNS, cloudflare for example, but those devices still end up using nextdns based on the logs. One of the reasons I prefer to use the installer is that it at least sometimes connect to my nearest node. Using dot in merlin, or using Android's private DNS features seems to permanently connect to further nodes.

The cli will use geo steering to send you to the closest pop. I would be curious to understand how it does not work for you.
There is no easy way to do what you ask for with cli. Please contact us on the chat again so we can understand your issue.

Would recommend to test with DNSCrypt installer instead and set it up with NextDNS, DNS-filter will work fine with that installer.

Hello, a long-time-reader-but-first-time-writer here. Have mercy and patience on me, guys 
I have got the NextDNS cli client installed on my RT-AC66u_B1, running Merlin 384.19. I am on a paid yearly subscription and overall I am happy with the service. There is though one detail which doesn't work for me as good as it promises which is logging the devices by their names. The IoT devices (like e.g. MusicCast speakers) are the biggest mess, but even my iPhone sometimes logs under its original iOS name, sometimes it shows up as an asterisk and sometimes under the device ID from the https://test.nextdns.io/ webpage. The only thing that is consistent is the IP address of each device.
It doesn't fundamentally affect the overall NextDNS functionality, but it would be nice to get it right and e.g. be able to immediately and reliably differentiate the online activity of my daughter and my son on their respective devices Would you have any idea what may be causing it? Or even better, how to fix it?

The nextdns CLI will disable DNSSEC and DNS Rebind because it interferes with the adblocking.

@Olivier Poitrey I noticed that this test page performs a GET request to a secured version with a unique(?) ID in front of the URL.
If I want to immediately perform that GET request, which URL should I use? (only the one with the ID in front seems to work? And how do I know which ID?)

Dear @Olivier Poitrey , when you respond, could you also kindly look at my question from the post #507 above?
I have a freshly reset RT-AC86U [384.19] and have installed nextdns from the github page. Installation goes smoothly, but upon a restart of the router, when I run the 'nextdns' command, it says:
-sh: nextdns: not found
I don't have anything else installed at this point, just a stock setup with dns servers added for nextnds on ipv4 (ipv6 disabled). When I check 'services-start' it looks fine with:
[#!/bin/sh
/jffs/nextdns/nextdns.init start]
and [/jffs/nextdns] has the 3 files all visible. When I run the installer again, it remembers my id when I go through the config. Also, when I run ps -w, it shows:
[1404 malaka 782m S /jffs/nextdns/nextdns run]
so does it mean its running but I just can't access any of the nextdns commands?

Similar experience here. After a reboot I must always enter the full path /jffs/nextdns/nextdns <command>. Should it work to just enter "nextdns"?
I started getting errors (fatal runtime out of memory) errors a week or so ago. I have a 3 year old RT-AC86U with a fresh flash of latest asuswrt-merlin. I just tried running an upgrade for NextDNS and received these errors below. Could this be my memory failing on the router?

Is there a way to be notified when this is updated?

The only way I am aware of is through your software updater notification - in case you have a Linux PC. The updates for the Merlin client are usually synced with the updates for the Linux CLI client.
I believe they use Github, so you could follow their github repo to be notified when there are changes to it.
