No Ethernet connection

My Mac 27" works on Catalina 10.15.

It's over a year now the ethernet stopped working. I have access to the internet via home wi-fi only. I restarted the Mac, restarted the modem, spoke with my ISP provider but no solution.

I get the message "Cable unplugged". I tried just to eliminate the possibility of bad cable with other computers and it works fine.


Can somebody help please??

Thanks

iMac 27″, macOS 10.15

Please post the entire report. However the little that I do see shows you have a third party antivirus app installed. Please read the following:


The best antivirus, cleaning app, and overall maintenance app for Mac OS is Mac OS itself. All you need to do with Mac OS to keep it secure and running well is to keep it up-to-date and do periodic (about 1x per week) restarts. Other than that, leave it alone. Adding third party antivirus, cleaning, security and other types of maintenance appsto Mac OS adds no additional level of security. The only thing these apps dois have the opposite affect users want. They make Mac OS slow, unstable, generate odd behavior (much like you are experiencing) and make Mac OS appear buggy.


Please locate the developers uninstall instructions for TotalAV and follow to the letter. Then restart in Safe Mode per the directions in Use safe mode to isolate issues with your Mac and then restart normally.
