7 Ways to Fix “Default Gateway Is Not Available” Error

Default Gateway Is Not Available: 7 Solutions Error How to Fix the Error Message "Default Gateway Is Not Available"


In the previous session in this Hands-on Networking Training Series, we learnt all about Network Address Translation in depth, including examples

The notion of the default gateway and its significance in computer networking systems will be discussed in this lesson.


Many times, while surfing the Internet and researching websites, we run into an internet connection problem, and when we attempt to figure out why, we receive a warning that the "default gateway is not available." Let's learn what it means and how to fix it.

7 Ways to Fix “Default Gateway Is Not Available” Error - best driver update


What is the Default Gateway

When no next hop IP address is defined in the routing table for the forwarding of a data packet to the target host, a default gateway is a router or network node in the computer networking system that acts as a forwarding hop to the other networking system.

As a result, when one network needs to interact or transfer data packets to another network, the default gateway will operate as an access point. This covers changes to the system's IP addressing and subnet mask, as well as network topologies.


If the IP packet does not locate a sufficient set of rules and route to follow to transport the packet to the target address at some instance of the node, it will use the default gateway for the rest of the routing procedure.

As a result, the default gateway is defined by a set of specific settings known as the default route. The router that connects the LAN network to the Internet acts as a default gateway for all network components in small workplaces or residential networks.


How to Fix the Error

Solution 1: Delete all MacAfee apps from your computer

The McAfee security product installed on the PC is one of the explanations why the "default gateway is not accessible" message. To resolve this issue, go to your PC's control panel, click on programmes, and then pick the programmers and features option.

Go to the Add or Remove Programs tab and pick McAfee, then uninstall it fully.


Your problem will be fixed after you uninstall this software. Other security programmes can be installed to make your machine virus-free.


Solution 2: Reset the Ethernet or Wi-Fi adaptor.

You may resolve the problem by deactivating and then enabling Wi-Fi from the network and Internet sharing settings.

The following are the steps involved:


  • Select the network caption with the right-click menu.
  • After that, choose "Open network Internet settings." Then select "update your network settings" from the drop-down menu.
  • Select Change Adapter Settings from the menu by clicking on it. Your Ethernet connection adaptor will be shown. You can decide afterwards.
  • After you've selected it, right-click it and select "disable." Allow some time to pass. After that, pick "Enable" and dismiss the menu after it has been activated.


Solution 3: Update the drivers for your network adapter.

If the caption "default gateway is not accessible" appears on your PC, you must upgrade the network device drivers to the most recent version. This is one of the options, but it does not guarantee that it will fix your problem.

Download the driver software from your hardware manufacturer's secure website and install it on your device.


The procedure is as follows:

  1. Go to your computer's device manager.
  2. Then, by right-clicking on the caption, expand the network adapter choice.
  3. After expanding it, the current driver version will be shown, and you'll need to choose Update Driver Software from the contextual menu.
  4. Select this option and then look for driver software that has been automatically updated.
  5. Get the software you need.


If the automatic search yields no results, manually look for and download the latest software. The problem will be resolved as a result of this.


Solution 4: Disable the auto-login feature on your Windows

Auto-logon is a recently added function of the Windows account of the user that would continually log in and was utilised before the PC was turned off.

This function will clash with the Windows network settings feature, resulting in the error "default gateway is not accessible."

Disable the function or set a password to log in so that it will prompt you for a password every time it powers up, rather than taking it automatically.


Solution 5: Uninstall your network adapter drivers.


It's also one of the most widely used solutions for the "default gateway is unavailable" problem. You must delete the network drivers completely from your PC. The consequence of the lack of drivers should not be a problem since when you reboot your system, Windows will identify and replace the missing drivers.


The following are the steps involved:


  • Go to your computer's device manager.
  • Then, by right-clicking on the caption, expand the network adapter choice.
  • Click uninstall after expanding it.
  • Restart the computer once you've finished removing.
  • Once your system boots up, the network adapter will be recognised and reinstalled.


Solution 6: Change the network adapter drivers.

It's one of the time-consuming and difficult procedures for resolving "the default gateway is not accessible to issue." We will replace the network adapter drivers with a different set of drivers that were previously installed in the system throughout this procedure.


The procedure is as follows:


  1. Go to your computer's device manager.
  2. Then, by right-clicking on the caption, expand the network adapter choice.
  3. After expanding it, the current version of the driver will be presented, and you must choose the update driver software option from the contextual menu.
  4. Next, two options will appear on your screen, and you must choose "search my computer for driver software."
  5. Then choose "allow me to choose from a list of device drivers installed on my computer."



  • Uncheck the option to display suitable hardware as well.
  • Select the Broadcom 802.11f network adapter if you were previously using the Broadcom 802.11b network adapter in the device manager, and vice versa. Then, as indicated in the picture below, select the following option:



  • If this does not resolve your issue, you may need to replace the adapter with a different set of network adapters.


Solution 7: Change the frequency of the Wireless Router.


The next generation routers operate on the 5GHz frequency, however your adapter may not be capable of supporting this frequency. As a result, alter the frequency from 5GHz to 2.4GHz to address the gateway problem. The processes for adjusting the frequency will be detailed in the router handbook, so you may follow them and make modifications.


Conclusion

We've learned about the default gateway's role in networking systems through examples in this course.

With the help of many screenshots, we have also figured out how to resolve the "default gateway is not available" problem.

We hope you've liked this networking series' whole collection of courses. We are certain that this set of courses will be an excellent resource for anybody, whether they are a novice or an expert!!
