Can anyone help me here?
I try to fix connection problem in macbook pro (Retina, 13-inch, mid 2014)
and macOS Big Sur Version 11.5.2.
Connection can work sometimes and then it just can't connect to internet any more.
Somethimes browser start connecting again after 10 minutes or more.
Problem is the same in wifi and ethernet.
I have made diagnostic test and I have monitoring results of dropped connection failure.
But I don't know what to do with it.
Have you tried unplugging your modem and/or router for a minute and reconnecting power to them? Give them at least five minutes to finish booting before you reboot your Mac to test the connection.
You need to figure out whether the issue is with connecting to your home network, or whether the issue is with your ISP or your local Internet. You can use the Apple WiFi troubleshooting tool found on the context menu when you Option-click on the WiFi icon. Here is an Apple article for troubleshooting WiFi issues:
If your Mac doesn't connect to the Internet over Wi-Fi - Apple Support
Try creating a new user account and testing the connection while logged in with the new user account. It is possible you have a configuration setting issue, browser extension issue, or a macOS network configuration issue.
Also try booting into Safe Mode which will disable third party items and even login items which will eliminate many potential software issues.
If you are using any anti-virus apps, cleaning apps, or third party security software, then uninstall them by following the developer's instructions. These types of apps are not needed on a Mac and usually cause more problems than they solve plus they impact system performance. You may also want to remove any browser extensions.
Do you have the same issue when using a different browser?
Do you have any other devices connected to your home network? Do they experience the same issue? Perhaps one of those other devices is causing the problem. Try disconnecting each other device from your home network in case one of those devices is causing the problem. You may also have a faulty router or modem. Make sure the firmware of the router is up to date. The router should have an option to reset the router to factory defaults (make sure to at least reconfigure the router by disabling external administrative access and to change the administrative password of the router).

Thank you for your answer, but none of your suggestions does not help.
Problem is the same when using other user or in safe mode.
No anti-virus apps or cleaning apps are installed
Problems are the same in safari and in firefox.
Many other devices can connect to internet using same router
both ethernet or wifi and they have no problems.
I have unblugged and also reseted the modem.
Problem is not in modem or in wifi. It is in connection to internet.
connection disappears all the time
