There is a D-Link DPN-R5402 from Rostelecom, a cord to the computer and a couple of devices connected via wifi, the Internet began to disappear from time to time, only restarting the router helps. Can anyone come across this?

Answer 1

what does the provider's support say? this is the first place you should go

Answer 2

That's right, you'll go straight to the provider's technical support, but before that you can try to localize the problem yourself.
During the problem:
1) Is the router being pinged from the LAN?
2) Can I access it from the local network?
3) Connection status (it would be nice to specify the type of connection)
4) Do you have pings to the provider's gateway and any external resource by ip (for example, 8.8.8.8)?
5) If the router allows you to ping from the interface or console, then repeat the pings directly from it
. The information received will allow you to understand at what interval the problem occurs
