After a massive upgrade to my computer, my Ethernet connection has stopped working. I have a netgear router (I can't find the exact model), but I doubt that's the problem as it worked fine before my upgrade. I installed an MSI B250M motherboard, and an i5-7600k. Every time I start up my computer I have the ability to do a google search, but that's where my internet capabilities end. If I take my Ethernet cord out and put it back in it will usually work after a few tries. All of my drivers are up to date, I have tried many admin cmd commands with ipconfig and netsh, scanned with multiple antivirus programs, and set up google dns but none of it is working. I'm just about at the end of my rope with this, I'd really appreciate some help.
