We learned everything about Network Address Translation in detail in this Hands-on Networking Training Series along with examples in our previous tutorial.

The idea of the default gateway and its function in computer networking systems will be addressed in this tutorial.

When surfing the internet and exploring websites, we often encounter an internet connection problem, and when we try to find the solution, we get a message that the “Default gateway is not available“.

Here this article will help you out of the problem. Let’s go through it.

What is the Default Gateway?

A default gateway is a computer networking device router or network node that serves as a forwarding hop to the other networking system if no next hop IP address is specified in the routing table to forward a data packet to the destination host.

Therefore, if one network wants to communicate or send data packets to another network, the default gateway can serve as an access point to other networks.

This also involves the modification of system and network topology IP addressing and subnet mask.

Generally, each network component in any network maintains a routing table stating on which port or interface the communication will take place, the set of rules to be followed and the route to be followed in order to deliver the destined data packets to the network.

If the IP packet does not find the appropriate set of rules and route to be followed in some instance of the node to transmit the packet to the destination address, then the default gateway will be selected for further routing.

How to Fix the Error?

Method 1: Remove any and all of the MacAfee programs from your PC

The McAfee security program installed in the PC is one of the reasons for showing that “default gateway is not available.” Therefore, go to your PC’s control panel to remove this problem, then enter programs and go to the program and features option.

Go to add or delete the program option from this screen and choose McAfee and then uninstall it full.

The problem will be solved after you uninstall this program. You can download some other security service to make the device virus free.

Method 2: Reset the Wi-Fi or Ethernet adapter

You can fix the problem by disabling and then activating the network Wi-Fi and the Internet sharing list.

These steps are as follows:

  • Right-click the caption of the network.
  • Now selects the “Open the Internet Setup Network”.
  • Now Update your network settings.
  • Now pick Adapter Settings from the menu update by clicking on it. It will show your link adapter for Ethernet. You can choose that later.
  • After you have selected it, right-click it and choose the option “disable.” Wait a little while. Then select the option “Enable” and close the menu after it is activated.

Method 3: Update your Network adapter drivers

If you get the caption that “the default gateway is not available,” you need to update the latest version of the network adapter drivers on your PC. This is one of the options, but it doesn’t mean it’s going to solve your problem.

Download the driver program from your hardware manufacturer’s authenticated page and install it on your computer afterwards.

The steps are as follows:

  • Go to your PC’s device manager.
  • Then, by right-clicking on the caption, expand the network adapter option.
  • After expanding it, the driver version you are currently using will be shown where you need to pick from the context menu the update driver code option.
  • You can pick this option and then check for driver software that is automatically modified.
  • Download the appropriate software.

If there is no appropriate result for the automatic scan, then search for the updated software manually and then access it. This will solve the problem.

Method 4: Make the Auto-Login feature of Windows Disable.

The auto-logon is a newly introduced feature of the user’s windows account that would log in twice before the Windows shutdown.

This feature clashes with the Windows network settings feature, resulting in the issue of “default gateway is not available.”

To fix it, disable the feature or you can log in a password so that it will require a password every time it boots up and will not take it automatically.

Method 5: Uninstall your network adapter drivers.

Also, fixing the “default gateway is not available” issue is one of the popular solutions. The network drivers must be completely uninstalled from your computer. One should not be concerned about the effect of drivers ‘ non-existence as the windows should detect and reinstall the drivers when you restart your program.

The steps included are as follows:

  • Go to your PC’s device manager.
  • Then, by right-clicking on the caption, expand the network adapter option.
  • Press Uninstall after extending it.
  • Reboot the machine after successfully uninstall.
  • Once your device is booted, the network adapter will be detected and reinstalled.

Method 6: Change the Network Adapter Drivers.

It’s one of the long and complicated repairing procedures “The default gateway is not available for problem.” In this process, the network adapter drivers will be replaced with some different set of drivers that are already installed in the device.

The steps are as follows:

  • Go to your PC’s device manager.
  • Alternatively, by right-clicking on the caption, expand the network adapter option.
  • After expanding it, the driver version you are currently using will be shown where you need to select from the context menu the update driver software option.
  • First, two choices will be shown on your monitor and you need to select “Browse my driver software system“.
  • Now proceed to “My Computer driver Software“.
  • Also, uncheck the hardware compatible display feature.
  • If you are using a network adapter in the device manager as Broadcom802.11b before, then select the network adapter for Broadcom802.11f and vice versa. Then click on the next option as shown in the screenshot below:
  • If this doesn’t fix your problem, you can also change the adapter to fix the problem with some other set of network adapters.

Method 7: Alter the frequency of the Wireless Router

Set the frequency between 5GHz and 2.4GHz and this will solve the gateway problem.

The frequency change method will be defined in the router’s manual, so you can go through the above steps and make changes.


We have understood the role of the default gateway with examples in the networking systems in this tutorial.
