[RT-AC5300] Loss internet connection at exactly same time everyday

[Yoonkung]

I got RT-AC5300 running on merlin 384.8_2 and running FreshJR script.
I loss internet connection everyday at around 10 pm my local time(gmt+7), I am not sure this is from ISP or from my router setting because the rest of the time its working just fine.

here is the some of the log from today and it repeated everyday like this

24 hours is the default DHCP lease time for an IP address. I suspect that rather than renew the DHCP address your ISP is disconnecting. Leave the connection down for an hour, see if the disconnects then change to 11pm.
