In this article, we are going to show you several quick fixes that will surely resolve the “Default gateway is not available” issue and resume things to normal again.
What is Default Gateway
A gateway is an IP address that defines the node in your network setup through which the traffic leaves and enters the network.

In a home setup, the gateway will be the IP address designated to your router. Every device connected to a network maintains a routing table that includes information like the default gateway, MAC addresses, its own networking details, etc. When the stored gateway IP address is unreachable or incorrect, the Windows OS will display an error “Default gateway is not available.” Let us now continue to see how to fix the issue.
Fix “Default Gateway Is Not Available” Error
Perform the following solutions in the given chronological order, starting from less aggressive to more aggressive remedies.
Restart Router
If you have been in the tech industry long, you would know that most minor issues are resolved by simply restarting the devices. Try restarting your router. You will find a power button on the back of your router. Use it to switch off the router and leave it for 5 minutes. After 5 minutes, turn the router back on and wait for it to boot up properly. Once all lights are on and steady, check if you experience the same issue on your PC.
Restart Network Adapter
The network adapters can occasionally malfunction after running for several hours or having their configuration changed frequently. This can also cause them to not be able to function properly but is usually fixable with a simple restart. Restart the problematic network adapter (Wi-Fi or ethernet) using these steps on a Windows PC: When it reboots, check on your computer if the error message is gone and you can connect to the internet. Type in ncpa.cpl in the Run Command box. Note: If you are remotely connected to another computer, then disabling the adapter will lose the RDC connection. Right-click on the adapter and then click Disable from the context menu. Right-click the adapter and click Enable from the context menu.
Run Network Troubleshooter
Both Windows 10 and 11 come with built-in troubleshooters that automatically scan and apply fixes to different Windows components. You can run the network troubleshooter and attempt to repair any issues. Here is how: If any fixes have been applied, then check if you still see the “Default gateway is not available” error message. Click Run in front of “Network Adapter.” The troubleshooting wizard will then scan and apply any possible fixes.
Uninstall McAfee Antivirus
Several users have reported that the McAfee antivirus on their computers is causing the “Default gateway is not available.” They have been beating around the bush for far too long to resolve the issue, and finally discovered that McAfee was the culprit. If you are experiencing a similar issue and have McAfee installed, we recommend that you remove it immediately. Alternatively, you can download McAfee’s Consumer Product Removal tool and use it to uninstall McAfee products from your PC. The uninstallation wizard will now launch. When the antivirus has been removed and the computer reboots, check to see if the issue has been resolved.
Disable Third-Party Antivirus
Third-party antivirus software can block internet connections that they think are malicious. Occasionally, they only block some of the IP addresses, but since the Windows OS cannot reach them, it displays the “Default gateway is not available” error message. In such an instance, you need to disable this antivirus software and check if it fixes the issue. If it does, then you need to change your antivirus. Learn how to disable Windows Defender (Windows Security).
Disable Auto-login
The Windows OS has a feature where you are not required to put in your user account’s credentials and it will log you in automatically. Although it is a nifty, time-saving feature, it sometimes disrupts the smooth working of the OS. Disable this feature using the following steps in an attempt to get your network up again: When the computer restarts, log into your account and then check if the “Default gateway is not available” error has gone away. You can also use our top selection of disk imaging and backup software so you never lose your data or operating system again.
Reset TCP/IP Stack
If the TCP/IP protocol stack is not working correctly, you will have issues with your Internet connection, like the one we are discussing in this post. A relatively less aggressive way to fix this problem is to clear the TCP/IP stack and start fresh. Follow these steps to reset the stack, which also includes resetting Winsock: If this does not fix the issue either, continue down to perform other mitigation methods. These commands will release the IP assigned by the DHCP server, flush the DNS cache, reset the network components, and then re-fetch the IP address from the DHCP server.
Update/ Reinstall Network Driver
Outdated or corrupted network drivers are often the cause of a faulty and unstable internet connection. It may be possible that you have either an old or a corrupted network driver installed which needs to be replaced to rectify the issue. First, try to update your network driver to a newer, better version. However, if the latest version is already installed, then you must reinstall it. Here is how: Alternatively, you can click “Browse my computer for drivers” to manually update the driver if you have already downloaded a standalone driver for your network adapter from the manufacturer’s website. Type in devmgmt.msc in the Run Command box. This will automatically download and install the latest network drivers available. Once the driver is updated, continue to check if it resolved the problem. However, if the latest driver was already installed and your problem remains, try reinstalling the driver.
Prevent Windows from Turning Off Network Adapter
Although your network adapter may not be turning off, it may have entered the low-power state not allowing it to function properly. Perform the following steps to disallow the network adapter from entering the low-power state: Now that the network adapter will always be operating in its full state, check to see if the Default gateway is not available” error message has gone away.
Assign Gateway Manually
When a computer is connected to a router with DHCP enabled, it automatically fills in the routing table. However, since the issue has not yet been fixed, maybe manually assigning the gateway will change that. Before we begin to assign the gateway manually, we must first know the following details regarding the router, as well as your own device:
Device’s IP address Subnet mask The gateway IP address
Follow these steps to find this information, and then use the exact info to assign them manually: When done, wait for a few seconds and then check to see if the “Default gateway is not available” issue has been mitigated. If the problem still persists and the error has not gone away, then the only thing left for you to do is reset the router.
Reset the Router
You can reset a router by using the tiny button on its back. Press and hold the reset button for 10 seconds while it is powered on. In some older routers, the reset button is not on the outside. Instead, you need to use a pin or a needle and insert it into a small hole on the back side of the router to push the reset button. The duration for pressing the reset button is the same. Note that resetting a router undo all configurations – even the ones done by your ISP to establish the internet connection. Therefore, you might have to get it set up again. This should surely fix the “Default gateway is not available” issue and get your internet working again.
Final Thoughts
If you see the “Default gateway is not available” error message on your PC, your first go-to should be towards restarting both the devices – the router as well as your network adapter or PC. If that doesn’t fix it, disable all antivirus installed on your PC and check your P configuration. W understand that troubleshooting this error can be tiresome, but you cannot access the internet or your network without resolving it first. We hope that the solutions given in this post helped you resolve the error promptly.
