Cannot Ping Computer on Same Network: Troubleshooting Steps

Rob Leung

When multiple computers are connected to the same network, they should be able to communicate with each other without any problem. However, sometimes a user may experience an issue where they cannot ping a computer on the same network. This can be frustrating and may prevent the user from accessing important files or resources on that computer.

There can be several reasons why a computer cannot be pinged on the same network. One common cause is a firewall that blocks incoming ping requests. Additionally, incorrect network settings, such as an incorrect IP address or subnet mask, may also cause this issue. Another possible cause could be a problem with the network hardware, such as a faulty network cable or a malfunctioning router. In this article, we will explore some of the common causes of this issue and provide possible solutions to help users troubleshoot and resolve the problem.

Fundamental Checks

When troubleshooting a networking issue where a computer cannot be pinged on the same network, it is important to start with some fundamental checks. These checks can help identify and resolve the issue quickly and efficiently.

Verify Network Connectivity

The first step in troubleshooting is to check if the network is working correctly. This can be done by checking the connectivity of other devices on the same network. If other devices on the network can be pinged successfully, then the issue may be isolated to the specific computer.

To ping other computers on a network, you can follow these steps:

  1. Open Command Prompt (Windows) or Terminal (Mac/Linux)
  2. Type the Ping Command
ping [IP address or hostname]

Check IP Address Configuration

The next step is to check the IP address configuration of the computer. This can be done by using the ipconfig command on Windows or the ifconfig command on Linux or macOS.

ipconfig (on Windows) and ifconfig (on Unix-based systems like Linux or macOS) are command-line tools used to display network-related information for a computer’s network interfaces. These commands provide details about the configuration of network interfaces, IP addresses, subnet masks, gateway addresses, and more.

inet netmask 0xffffff00 broadcast
nd6 options=201<PERFORMNUD,DAD>
media: autoselect (1000baseT <full-duplex>)
status: active

Make sure that the IP address, subnet mask, and default gateway are all correctly configured.

If the IP address is set to a static IP, ensure that it is not conflicting with another device on the network.

Examine Hardware Connections

If the network connectivity and IP address configuration appear correct, the issue may be related to hardware connections. Check that the network cable is securely connected to the computer and the network switch or router. Make sure the wireless adapter is set up and connected correctly if you’re using a wireless connection.

By performing these fundamental checks, it is possible to quickly identify and resolve networking issues where a computer cannot be pinged on the same network.

Software Configuration

Firewall Settings

One potential cause for not being able to ping a computer on the same network is a misconfigured firewall. Firewalls are designed to block incoming traffic by default, and if they are not configured to allow incoming ICMP traffic, pinging the computer will not work.

To check the firewall settings, follow these steps:

  1. Go to the Control Panel
  2. Select “Windows Defender Firewall” or “Security and Maintenance” depending on the version of Windows
  3. Click on “Allow an app or feature through Windows Defender Firewall”
  4. Ensure that “File and Printer Sharing” is enabled
  5. Ensure that “Network Discovery” is enabled

Network Discovery Options

Another possible cause for being unable to ping a computer on the same network is that Network Discovery is turned off. Network Discovery allows computers and devices on the same network to discover and communicate with each other.

To check the Network Discovery settings, follow these steps:

  1. Go to the Control Panel
  2. Select “Network and Sharing Center”
  3. Click “Change advanced sharing settings”
  4. Ensure that “Turn on network discovery” is enabled.

Antivirus Interference

Antivirus software can also interfere with network communication, including ping requests. Some antivirus software may block ICMP traffic by default or may have other settings that prevent ping requests from being sent or received.

To check the antivirus software settings, the user can open the antivirus program and look for settings related to network communication or firewall settings.

Make sure the antivirus software isn’t stopping ICMP traffic. Set up the antivirus to let devices communicate within the network.

Troubleshooting Tools

Using Ping Command

The Ping command is a simple and widely used troubleshooting tool. It checks the connection between two computers by sending a small packet and waiting for a response. If the target computer responds, the connection is good. If not, there might be a network issue.

Network Diagnostics

If Ping doesn’t work, try other network tools for troubleshooting. Windows and macOS have Network Diagnostics tools that help find and resolve common network issues.

If the built-in Network Diagnostics tool can’t solve the issue, other third-party tools are out there to help. These tools offer detailed info about the network connection and can pinpoint more complex problems.

Here are some tools to help you diagnose:

  1. Wireshark: Wireshark is a powerful network protocol analyzer that captures and displays data going through a network in real-time. It allows users to inspect packets and understand network protocols, helping to diagnose complex network issues.
  2. NetSpot: NetSpot is a Wi-Fi analyzer and survey tool primarily used for wireless network troubleshooting. It assists in analyzing Wi-Fi coverage, discovering network issues, and optimizing wireless networks for better performance.
  3. PingPlotter: PingPlotter is a network troubleshooting and diagnostic tool that graphs latency and packet loss between your computer and a target destination over time. It helps identify network issues, visualize performance problems, and troubleshoot connectivity problems.

Advanced Solutions

Reset Network Components

If the basic troubleshooting steps did not resolve the issue and you still cannot ping a computer on the same network, resetting network components might help. To do this, follow these steps:

  1. Turn off the modem and router.
  2. Disconnect the power cables from both devices.
  3. Wait for at least 30 seconds.
  4. Reconnect the power cables and turn on the modem and router.
  5. Wait for the devices to fully restart and connect to the network.

Update Network Drivers

Outdated network drivers can cause issues with network connectivity. To update network drivers, follow these steps:

  1. Press the Windows key + X and select Device Manager.
  2. Expand the Network adapters section.
  3. Right-click on the network adapter and select Update driver.
  4. Choose the option to search automatically for updated driver software.
  5. Wait for the process to complete and restart the computer.

Check for System Updates

If the issue persists, checking for system updates might help. To do this, follow these steps:

  1. Press the Windows key + I to open Settings.
  2. Click on Update & Security.
  3. Click on Check for updates.
  4. If updates are available, download and install them.
  5. Restart the computer.

Seeking Further Assistance

If you try these advanced fixes and third-party tools and still can’t ping a computer on your network, consider hiring a network admin or IT support for more help. They may have additional tools and resources to troubleshoot the issue, such as network monitoring software or access to router settings. You can also get more help by checking online communities and forums.
