Time Synch fail & WAN connection loss

#1

Almost like clockwork, each night I lose my internet connection. After looking through my logs, I see a time synchronization failed message around the same time I lose my connections. Here is a sample.

Hi,
in the Log I found the following lines

So, it seems to sync the Time.
Is it a DSL-Line? In Germany for example the ISP will reset your connection every night.

Regards
Dennis

This logs below be a better representation of my problem. I have cable internet, and each time I lose my connection, I have to reset the power on my router to get my internet connection back. I don’t know of any nightly resets from my cable company. Thaanks

It happened again tonight, and twice. Around 10 PM or so, the router dropped its WAN connection so I reset the router. Then at about 1130 or 1145 it dropped the connection again. I have noticed that when it does this I can’t login to the router, and I have to unplug it to reset it. Here is a log showing time sync failures. Even if it succeeds a time or two, it will still fail around 10 PM and drop my internet connection. My cable TV stays working, and I have the default time server on the router. Maybe its not the time synch problem but I’m not sure what else to look for or how to enable additional logging. I’m really stuck on this so any help is greatly appreciated. Here are logs.

@jachin99

How long the device being deployed in the network ? The problem just happen recently ? If the issue happen recently, may i know the any recent changes for the network ?

Possible please open support ticket for support team to check:

Not easy to investigate the issue by looking at the partial logs that cut out as shown in the previous logs.
