Problem with my Dell Latitude E6410 device.
It seems your laptop frequently shows no internet connection after about 20 minutes of use. You've already tried reinstalling Windows, updating drivers, and checking the network card connection. Could you share any other details or symptoms?
Use the onboard DELL diagnostic tool (press F12 at startup). Consider installing a Linux distribution such as Ubuntu to check for identical problems.
If it functions on Ubuntu, it indicates a Windows-related problem, probably involving the driver.
