I've been working on this for over two hours now. I have wifi on laptop. In Windows 10 I can't access internet on PC with Ethernet. On the same computer I have a Linux Mint partition and ethernet connection is fine there 160Mbps. I've unplugged (several times) modem and router. I've disabled and reenabled ethernet. I've turned off the PC and restarted. I've done all the Ipconfig commands, however "release" doesn't work as there is no media detected. About two weeks ago my ISP upgraded their modem to a 150Mbps. Since then I have been using Linux so this is the first time I've booted to W10. It worked fine before. Right now I'm waiting for a tech sevice call back from my provider to see if they can sort it out; thought I'd try here also.
TIA, Allan
