Yellow Triangle: WiFi Connected but No Internet Connection Message - Router Issue

I am warning that I am green. I write with poor phone quality, so please forgive mistakes

Appeared from day to day. Everyone at home is connected to one router and has an internet connection. For me, although I am connected, I have a yellow triangle next to the Wifi sign and the message "no connection with the Internet". Why?

1. Someone may have a restriction on your modem on your computer that blocks access to the internet.
2. The modem has not assigned you the correct ip address or there is a duplicate ip address on the network
3. Your anti-virus or firewall blocks network traffic after the upgrade
4. Some unwanted software is blocking access to the network
5. And many other reasons ...

Check if you can connect from your computer to the modem, depending on the modem and configuration, addresses may be different, check the sticker on the bottom of the modem. There should be a modem address (e.g. 192.168.1.1) with login and password. And we will see what to do next

After restarting the computer, it happens that I can go to the server side, another but only for about 30 seconds. After that the internet disconnects and until it disconnects and connects again it does not work. The Wifi icon after it stops working for some time as if it is active, i.e. showing an internet connection but after a while showing a total disconnection.

Added after 3 [hours] 5 [minutes]:

PS: I can't connect to the router address between these gaps. Nothing works when it comes to internet until you disconnect and reconnect.

And everyone (you too) are in the same room?

Install InSSIDera v2 / Home on your computer, and here enter the measurement result of the network - all are to be visible.
