Restarted after new Nvidia driver now ethernet doesnt work

[osakran]

I installed a new Nvidia driver and since the restart the ethernet connection will not work. It says its connected and working but only some websites work. The WiFi is working fine.

If some sites work and others don't then you must have a connection going through. I see no reason nvidia driver would affect your network at all. You haven't installed anything else since the last time you rebooted before this?

Many ISPs give their customers access to both an IPv4 and an IPv6 address. What happened to you can occur if your Ethernet adapter gets an IPv6 address, but fails to get an IPv4 address. What the users sees is access to google.com and youtube.com (which work with IPv6 and IPv4) and no access to intel.com or tomshardware.com (which only work with IPv4).

Installing the nVidia driver probably messed up the DHCP client that gets your IPv4 address. Resetting the adapter should fix the problem (In Windows 10 type "Network Status" in the search bar next to the start button. On the page that comes up, scroll to the bottom and look for "Network reset". Click that and follow the prompts.)

I have the same problem on one of my wired desktops. I don't want to install a wifi card for speed. I tried the Network reset and reboot, but there was no change. If I ping a site like cnn.com I get a ipv6 good ping. If I ping an ipv4 site like espn.com I get the ipv4 and network unreachable. It does translate the name to an ip. It just doesn't connect via ipv4. ipconfig show I go have a ipv4 and ipv6 addresses assigned, but the gateway, DNS servers show ip's in my own subnet. I am pretty sure this started after upgrading my nvidia driver to 417.71
The only sites that work are gmail and facebook.

Gmail and facebook work because they use IPv6 (you will find the google and youtube will also work). So why is IPv4 not working? Try this:

1. Ping your router. "Ping 192.168.1.1" (or what ever the address for gateway is in ipconfig). If this works, then it's not your computer.

2. Ping google. "Ping 172.217.14.174" ... if this works then it's not a network issue, but more likely a DNS issue.

3. Go into your network adapter properties and under IPv4 manually enter a DNS server address ... 8.8.8.8 ... like this.

Yes the failure was in step 2. So used the DNS number and it started working again. I then set it to the comcast recommended values and it seems to be all fixed now. Thank you very much.
