Why does the router periodically disappear - restart the network?

Question

WiFi

Tell me, there is a keenetic 2 router . The connection suddenly breaks for a few minutes, in the logs this:

UPnP::Manager: redirect and forward rules deleted: tcp 54815. 
Oct 25 00:10:29ndhcpcSwitch0/VLAN2: sending REQUEST for 185.3.174.153 to 185.3.172.1.

Oct 25 00:10:29ndnproxyupdating configuration...

Why can this happen? Occurs suddenly when I'm online.

Answer 1

There is nothing in your logs related to the break. You can see only the usual extension of the lease of the IP address from the provider. Either give a more complete log, or describe the situation in more detail.

Answer 2

I will assume that the WAN partition on the router may not be configured correctly. However, the Zixels have such a fairly simple Setup Wizard that it is very difficult to do something wrong with it. In general, open the WAN settings and you can call the provider's technical support, clarify whether everything is correctly scored there - this is their job so that everything works well for you.
