Hello
I just have change of ISP and I have a issue with ntp on my asus 86u:
- The previous ISP was with ISP modem (+bridge mode) and asus 86u routeur with static ip and I didn't have ntp issue
- The new ISP is with dynamic ip and fiber connection :)
- Using latest stock asus firmware, I can have the router synchronized with the ntp server => the ISP doesn't seem to be in cause
- if I connect to the routeur and I try ntp command I get a timeout
Code:
ntp -w -p pool.ntp.org
ntp: timed out waiting for 37.187.104.44, reach 0x00, next query in 2s
the DNS doesn't seem to be in cause.
Code:
nvram show | grep ntp
size: 66363 bytes (64709 left)
ntp_ready=0
ntp_server0=pool.ntp.org
ntp_server1=
ntp_server_tried=pool.ntp.org
ntpd_enable=0

I have try to change ntp_ready=1 and
Code:
service restart_ntp
service restart_ntpd
service start_ntp
service start_ntpd
but it doesn't help.
Any idea is very welcome

This work around has been used for past NTP issues. Try adding the line below to /jffs/configs/dnsmasq.conf.add. Then, reboot. 1.1.1.1 is Cloudflare DNS. You can change to another DNS if you prefer.
Code:
server=/pool.ntp.org/1.1.1.1

Thanks for reply.
I have try to add into dnsmasq.conf and set Wan: Use local caching DNS server as system resolver Yes or No
But it doesn't help
Code:
nslookup pool.ntp.org
Server:    127.0.0.1
Address 1: 127.0.0.1 localhost.localdomain

Name:      pool.ntp.org
Address 1: 37.187.104.44 herbrand.noumicek.cz
Address 2: 37.187.205.149 ntp19.kashra-server.com
Address 3: 51.159.6.183 51-159-6-183.rev.poneytelecom.eu
Address 4: 95.81.173.8 ntp-1.arkena.net

 ntp -w -p pool.ntp.org
ntp: timed out waiting for 51.158.147.92, reach 0x00, next query in 1s

As a countermeasure I have install ntp server on a raspberry pi and set the raspberry IP as "ntp server" in asus router, and it's working ...
It's not a perfect solution but at least it solves the issue.
