Dell network cable error and cannot access https website
Hello,
I am using a Dell Latitude E6540 laptop with Core i7 4800Q and 8GB RAM. Due to work needs, I reinstalled the Windows 7 64-bit operating system. Everything was normal until I went to the website to find the service. The problem is that all the pages on this site have errors. I also tried some other websites google.com but still got the HTTPS error.
Another problem is that when the computer is turned on or restarted, an exclamation mark appears in the device manager, resulting in no network access when the LAN cable is plugged in.
Driver is fully installed, downloaded directly from the manufacturer's support page.
Serial: <Private data removed from public view. DELL-Admin>
I look forward to receiving your support.
Any answers are appreciated.

Windows 7 is completely insecure, having had no updates for more than five years now. That's part of the problem.
The rest could be anything from a bad Ethernet port on either end or a bad cable.

"It's not a cable issue. I think there is a problem with the driver or the network controller IC. The error occurs when turning off the computer and turning it back on, displaying an exclamation mark, or when restarting the computer."

Make sure you have:
Fully patched as much as possible, Windows 7.
Installed the Intel chipset drivers, and rebooted.
Installed the network driver for your Ethernet chip.
You will still face https errors with any Windows 7 version, as it does not support current security protocols, but it should allow you limited activity online (at your own risk, subject the fundamental insecurity in an OS that was sunset in January 2020).
