Breaking the connection without losing data?

Question

Computer networks

Closer to the night, the Internet begins to disappear. I decided to check the stability of the connection by running cmd, in which data packets are sent to the Google server and back at a frequency of 1 second. cmd works fine. There is another departure of the Internet, but there is no packet loss. How is this possible? The gap occurs for 15 seconds, the Internet is turned off on the PC, and on all devices in the house, and for some reason data is still transmitted to and from the server without loss. What is this magic?

Answer 1

Hello.
This is probably missing DNS, and most likely your router is handing out dynamic IP addresses (DHCP). If DHCP is working, then check which DNS addresses the router is giving out.
If it issues its own IP as a DNS address (the IP that "looks" into the local network and is a gateway for devices), then its cache is probably updated and the process lasts 10-15 seconds.
If this is the case, then to fix this problem, reconfigure the router (DHCP server) so that it issues the IP address of your provider's DNS as the primary DNS (you can check with the rights provider or look in the settings of your router), and as the secondary IP address Google's DNS - a = 8.8.8.8 or 8.8.4.4
And if your router settings (DHCP server) allow, then you should not be limited to two DNS - you can install a pair from the provider (basically all ISPs have two DNS addresses) + two from Google -a = 8.8.8.8 and 8.8.4.4

Answer 2

most likely, dns falls off, and data is sent to the server to a clearly specified ip
