NTP not sync in RT68U

[The Tinkerer]

I solved the problem.

It was a firmware issue.

The fix was to do a factory reset, then, manually re-enter all settings. (DO NOT upload a saved configuration file.) I took screenshots of everything that had anything different from defaults, but this was still time consuming and a PITA. But it fixed both the "disconnected" problem, and also the NTP problem.

Factory reset fixed it?

I could have told you that!

Glad you've got your router in a good/known state again.

Wow. An argument could be made for blocking customer NTP servers but never NTP clients.

I can't see where ATT would block NTP client - server, yes...

Too many OS's use NTP client to keep time up to date...

The Asus router does function fine with the wrong date. But it's not ideal.

It should, but some scripts and external services might have problems with time being out of sync by an hour...

Hi All

i've been experiancing this problem since months on my RT-AC68U with merlin 386.13 . I have a huawei usb 4G modem without any cable internet, so I used wan usb as primary and I've disabled dual wan options.

I experianced that the internet is being dropped randomly and I could not figure out why. NTP keeps complaining about unable to sync therefore the date was back to may 5 as it has been told in several topics here

but, then letsencrypt disconnected the internet due to unsync time. And then there is a loop.

If I reboot the router it is holding for the internet connection for a while but then randomly disconnects.

I disabled letsencrypt for now, and for the first time in months it is still online for the next morning.

I'll keep you posted.

Did I miss something in the configuration or is it a bug? What do you think?

What NTP server is configured in Advanced Settings > Administration > System ?
The default is pool.ntp.org and works here.

Turns out the 3G/LTE usb stick breaks connection randomly therefore the NTP cant sync etc etc etc.... I keep trying to identify the issue but no success.

btw I have pool.ntp.org there and it is working fine as long as it is not disconnected

thanks for the reply anyhow

This is one of those use cases where Chrony might be useful...
