Ethernet does not have valid configuration

I have been having on-going Internet connection problems with Windows 10 for months. Initially running the Realtek driver repair program would fix the problem. Not any more. I have tried everything suggested from various posts to no avail. I have turned off everything but IP version 4. I just installed the latest driver from Realtek (10013_01172017). No luck. My windows 10 computer is a dual boot machine. Running LinuxMint 18.1 KDE accesses the Internet just fine every time. I am connecting to my cable company's modem via ethernet hard wired. I have rebooted the modem twice today.

My ipconfig /all results are as follows:

Microsoft Windows [Version 10.0.14393]

The IPv4 address listed above obviously does not connect to my ethernet modem. I would greatly appreciate any suggestions any of you might have to solve this problem.

Thanks for the response. In reading the thread on 'Repair Install of Windows' it states that you use the Media Creation Tool within Windows to download either the iso or the usb. Since I cannot connect to the Internet in Windows 10 this does not seem like a viable option.

Try setting a fixed IP see if it works then

Thanks again for your help. I'll give that a try

This morning I booted into Windows 10 to use my accounting program (the only reason I use Windows at all) and it successfully connected to the internet. I had made no changes in Windows and had not rebooted the cable modem--it just worked. Seeing this as an opportunity to act on the previous suggested fix to the connection problem I followed TenForums tutorial on "repair and install of Windows 10". As a result of that effort, now Windows will not boot at all. I get a "system thread exception not handled" error message. I have tried the restart option with built in troubleshooter twice with no luck. I tried the startup repair option to no avail. Under other potential actions Microsoft presents were 'Reset this PC', System Restore, System Image Recovery, Command Prompt, Startup Setting and 'Go back to previous built'. At that point I figured I had done enough damage so I turned off the computer and am now seeking advice as to how to proceed.

If you get the lates win10 iso https://www.microsoft.com/en-gb/soft...load/windows10 then do an upgrade its will keep all your setting software etc

Thanks for the quick response. I have downloaded the ISO file, but what do I do with it? Windows 10 won't boot so I can't follow the instructions in the TenForums for a "repair install of Windows 10".

After numerous attempts using all suggested methods over a period of several months I finally gave up. I reformatted the drive and reinstalled Windows 10 from my original Microsoft Disk. So far the system is working without any problems.
