Some of my clients have internet but most don't. I have a 1G up & down fiber line that checks OK. I rebooted my router, and it still hasn't synced with NTP time server. I lost all my scripts. Second reboot, same thing.
Any suggestions?
 
Unplug the power from the router. Remove all USB devices. Wait a couple of minutes. Power it up.
 
Disable "JFFS custom scripts and configs" in the GUI (Administration - System) and reboot. Then start to diagnose the problem. The first thing I would check is that the USB drive isn't corrupted and is mounting OK.

Done. No change yet. Not looking good. Still hasn't synced time.

Done. Usb seems OK, mounted ok. Scan doesn't show anything. Still some clients have no interenet, time hasn't synced. A lot of "*kernel:dropped*" in the log.
 
Check your WAN DNS settings are pointing to your ISP's servers or some other public servers, not any internal servers.
says "DNS Server: 9.9.9.11, 149.112.112.112"

Probably normal because you had Skynet installed which I think enables logging of dropped packets.

says "DNS Server: 9.9.9.11, 149.112.112.112"
That should be OK. What have you got set as the router's primary and secondary NTP Servers?

How about doing this from the router's command line:
Code:
date
service restart_ntpd
sleep 10; date

EDIT: Is it simply that your ISP connection is down? Check that your router has a working internet connection (does it say Disconnected on the Network Map?). Can the router ping 8.8.8.8? You said some clients still work - are these mobile devices that are failing over to an LTE connection perhaps?

pool.ntp.org, no secondary set

It says Connected. ISP connection appears good, they say it is. ping was good, till I broke it at 34 packets.
 
Is anything left but a factory reset? I need to take some screenshots.
 
I somehow doubt a factory reset will change anything if this was working OK until today.

Try running ntpd from the command line using different servers and see if it succeeds:

Strange. Sounds like your DNS isn't working.

Try:
Code:
nslookup www.google.com
nslookup www.google.com 8.8.8.8
nslookup www.google.com 9.9.9.11
and
Code:
cat /etc/resolv.conf
cat /tmp/resolv.dnsmasq
 
Have you also tried rebooting (don't shut down, then start again, that is not the same thing) the problem clients?

yes, several times with some.

I lost my prompt after google.com 9.9.9.11

Just close the program window and open a new one.

So far it's sounding like either a) an intermittent internet problem with your ISP, or b) an inability to reach Quad9's servers.

Try and complete the outstanding commands from my previous post. After that try changing your WAN DNS servers to 8.8.8.8 and 8.8.4.4

Ok, so it looks like a problem with Quad9's servers (or your ISP).

I'm not sure why you've got Stubby's IP address in your resolv file. I guess it's because you've enabled the VPN client in Exclusive mode and have DoT enabled as well?

I've got DoT enabled, but no VPN clients unless its an unused leftover or something. I had a VPN server. It's still showing the Quad9's as WAN DNS servers. Maybe a reboot will cure that. Still don't have internet for some clients. They are all present on the local network, they just don't have internet. I wonder if I could get by with Quad9's "normal" servers? Maybe they took those out for something.
