Windows 10: Connecting desktop PC to Ethernet or WiFi kills all internet

When connecting my Desktop Gaming PC to either Ethernet or WiFi, the entire internet is killed. No wifi or Ethernet traffic will work for any device. When Ethernet is unplugged or WiFi is disconnected from the PC, the internet comes back for all devices. Tried new routers, same issue happens. Reset the network configurations on PC. Attempted to update drivers for NIC. Intel I211-AT Gigabit Ethernet Connector. Unsure what might be wrong.

Internet Slowdown on my Desktop - Ethernet Connection

Thanks Vijay. I went through your steps other than the repair upgrade, and there was no change. Before I do the repair upgrade, I want to check on another angle.

I went into Networks and Sharing and realized that Windows is simply not recognizing my Verizon modem/router as the Ethernet connection. The slow internet access is due to the fact that the desktop is picking up the WiFi signal, and it's not strong on this
device.

For Ethernet, I get an "Unidentified Network" and when I click on Ethernet Status, the IPv4 and IPv6 connectivity lists "no network access". Looking at the Ethernet properties, the "Connect Using" lists Realtek PCle GBE Family Controller. Shouldn't it
be the Verizon modem name? Also noticed that the Microsoft Network Adaptor Multiplexor Protocol is unchecked. Not sure if that matters.

I think what I need to do is somehow configure the Verizon modem again, but not sure how.

 

How to share internet connection from desktop to wifi through router?

Hey guys,
can you help me set up home network?
I have a D-Link Dir-300 router, desktop pc with two network cards on board and notebook with wifi. And internet through local network vpn.

I want to connect internet to my desktop pc (cause it's faster then dir-300 connection) and then to dir-300 from second lan port for wifi sharing.
And use wifi on notebook.

How should i set up this?

 

share internet connection in pc desktop &laptop

Operating systems on each computer?

If the desktop has two ethernet connections, you can set it up so that one has the modem (internet) and the other is connected to the laptop (cable from desktop to laptop).

If you want wireless, you will need a router unless you have a wireless connection and ethernet connection on the desktop, in which case you can do the same above, only instead of cable from pc to laptop, its wireless connection from pc to laptop.
