my Acer 5534 works fine on wireless but my Ethernet port wont hard wire. (I need to hard wire for a job). I have run rkill scan/ malwarebytes/clcleaner to make sure there are no viruses. I have switched ports and cords. I even purchased a USB/Ethernet adapter. it doesn't work either. nothing helps. I'm running out of things to do. any suggestions besides buy a new computer?
