that looks like that output came from the router at boot time. I don't see any service stopping & restarting.
I am not very familiar with your router or u-boot. Maybe what we are looking is not available using dmesg..
someone else needs to jump in and let you know where to look for the syslog messages.
if it is your router causing your wan to reset everyday at midnight and not your isp, I would think there would be a syslog message showing some service stopping & starting, or just restarting.
if you are running a version of windows, think about using wallwatcher. you can watch the syslog & firewall in real time, or just the syslog.
I just checked my dmesg file located in /opt/var/log.
I looks like not everything gets put into dmesg. At least there are matches to wallwatcher, but wallwatcher has many more entries. It could be that I have told the router I have an external syslog server. _________________ [MODERATOR DELETED]
It is enabled... that's why my router disconnects and reconnects at the midnight? I'll give a try and come back with answer Thanks for ideea.
EDIT: Damn you're right ) I can't belive this was the reason Thanks!
I thought that option reconnects my internet connection when it's dropped from ISP after 5 seconds, but was the time... at 00:05 that's arround midnight.
