This error can occur due to outdated drivers, the computer conflicting on the speed of the connection, other applications conflicting etc. We have listed down a number of different workarounds available to solve this issue. Start with the first one and work your way down.

 

Solution 1: Checking Hardware

Before we proceed with the troubleshooting, you should make sure that your computer hardware isn’t at fault. Try plugging the Ethernet cable into another computer and check if the signal is being transmitted correctly. Also, check if the ends of the cable are not broken and you hear a ‘click’ sound when you insert the cable into your computer. After diagnosing the cable at your computer, diagnose the cable at the router’s side. Make sure that you have plugged it into the right slot and the ends present at the router are properly plugged in. Try plugging the computer’s end of the cable into the router and vice versa. Once you are absolutely sure that this isn’t a hardware problem, proceed.

 

Solution 2: Changing Duplex Settings

Duplex is a complex system implemented on all computers for managing the directions of your network communication. The value of this setting is automatic by default; Windows determines the best settings and applies it. After troubleshooting on various computers, we deduced that it was this setting that caused this error message in the majority of the computers. We can try changing this setting and check if this brings any difference in our case. Feel free to revert the changes if this doesn’t work.

  1. Press Windows + R, type “devmgmt.msc” and press Enter.
  2. Expand ‘Network adapters’, locate your Ethernet adapter, right-click it and select Properties.
  3. Navigate to ‘Advanced’ tab. Navigate through all the entries until you find “Speed and Duplex”. Click it and change its setting from “Auto negotiation” to “100 Mbps Half Duplex”. Press Apply to save changes and exit.
  4. Restart your computer, plug your Ethernet connection back in and check if the problem at hand got solved.

Note: If “100 Mbps Half Duplex” doesn’t work, try using other options available. The Duplex settings might vary computer to computer as each of them have different specifications.
