Welcome to CoreNetworkZ Tech Solutions. Today, I will explain a network error message- Error 678: The remote computer did not respond.
Yesterday morning, my friend called me to fix a network connectivity issue.
He tried to access the Internet with his BSNL Broadband connection but failed. Whenever he tried to connect to the Internet, he saw an error message -Error 678: The remote computer did not respond.
Since he was using BSNL broadband, he called their technical support.
He spent more than forty minutes with them. Still, they could not resolve it. This issue persisted even after an hour, so he called me for a solution.
Reasons For Error 678: The remote computer did not respond
I understand that many readers, like Anil Thomas, want to know the reasons behind this error message.
Anil Thomas, in his comment, asked this question.
So, let me explain the reasons here.
Error 678 is due to poor connectivity. The poor connectivity can be due to a faulty Ethernet cable, a loose connection between modem and computer, or even the modem might be corrupted. Some other possible reasons (other than modem faults and connectivity issues) are TCP/IP issues, Firewall blocking, or Malicious programs running.
I hope this answer satisfies Anil Thomas. Now, let me explain the steps to fix error 678. The steps provided here apply to all types of modems.
How To Fix Error 678: The Remote Computer Did not Respond?
As I explained, the primary reason for Error 678 is poor connectivity. So, we must conduct steps to check the connectivity. If that part is correct, then we must proceed to system-level troubleshooting.
Check the Cables Connected
We need to ensure that the Ethernet cable is not faulty and the connection is perfect. Check the following connections and ensure the respective LED lights on the modem are on.
Modem and splitter connection
Modem and Computer connection
Jack in & Jack out of the splitter
Matilda Antony asked in the comments section how to identify if the connection has issues. My answer is to check the modem LED lights.
Power Cycle the Modem to fix Error 678
CoreNetworkZ Tech Solutions recommends power cycling the network as the most effective solution to fix Error 678: The remote computer did not respond.
Reset Winsock and Restart your computer
I received comments from Melvin John saying the second step could not fix it.
If the second step could not fix the error, reset the Windows Socket. Then reboot your computer. The following link will explain the entire procedure.
Check whether the Firewall blocks your Internet connection
Ashish Mudgal, a senior network engineer at CoreNetworkZ Tech Solutions, mentioned the role of Firewall applications in generating error 678.
He recommends turning off the Firewall programs (Including Internet Security Suits) to troubleshoot the problem.
Check for Virus Infection
There is a chance that your PC has network worms or other malicious programs. So I strongly recommend you scan your PC using a trusted Antivirus program.
Reset and Reconfigure the modem
The last possible step to fix Error 678 is to reset and reconfigure the modem. I do not recommend you perform this (the reason why I give this step only last) if you do not know how to configure the device again.
I suggest you follow this step with the guidance of the respective ISP technical support person. To learn how to reset a device, click on the link below.
This tutorial explained different steps to fix the "Error 678 The remote computer did not respond " message. If the issue persists, I recommend you contact your ISP and ask whether the error is with the ISP side. If the modem is faulty, they may replace it.
