Right-click on the grayed-out network adapter and choose Enabled.

4. Change Advanced Power Settings for the Wireless Network Adapter.

If you're using a battery saver power plan, your computer might be putting your wireless network adapter to sleep to save on power. To avoid the frequent disconnection issue, you need to change and set your network adapter to use the maximum performance power plan.

Change the advanced power settings for the network device using Power Options. Here's how:

Press Win + R to open Run.

5. Update Your Network Adapter Drivers

If the issue occurs after a Windows update, your computer might be missing the latest updates for the network adapter driver. The new drivers may sometimes be unavailable via the Device Manager and require you to manually download and install them from your computer manufacturer's website.

Follow these steps to update your network adapter drivers. To update network driver using Device Manager:

Press the Win + X key to open the WinX menu.

Click on Device Manager to open the app.

In Device Manager, expand the Network Adapter section.

Right-click on your network adapter and select Update driver.

That said, Device Manager sometimes doesn't have the latest drivers available. So, your best is to check your computer manufacturer's website and download all the latest drivers available for your computer.

Alternatively, almost all the major computer OEMs ship the computers with their proprietary system management utility. For example, Lenovo offers Vantage and HP offers its Support Assistant utility. You can use these tools to check for pending updates and install them without the need to visit the website.

6. Perform a Driver Roll Back

Windows features a driver rollback feature in Device Manager. You can use it to roll back a driver update and undo any changes that may have occurred.

To perform a network driver rollback:

Open Device Manager.

Expand the Network adapters section.

Right-click on the network adapter and select Properties.

Next, open the Driver tab in the Properties dialog.

Click on the Roll Back Driver button. Click Roll back to confirm the action.

Once done, restart your PC and check for any improvements. If the issue persists, open the network adapter properties and try to perform a rollback again. If the option is grayed out, you don't have any older drivers to install.

7. Change the Network Adapter's Power Management Option

Your Windows computer can turn off some devices to save power when idle. However, this can result in frequent service disconnection. To fix the problem, disable the Allow the computer to turn off this device to save power option in Device Manager.

To disable the network adapter power management option :

Press Win + R to open Run.

Type devmgmt.msc and click OK to open Device Manager.

Next, expand the Network Adapters section.

Open the Power Management tab in the Properties dialog.

Uncheck the Allow the computer to turn off this device to save power option.

Click OK to save the changes.

Restart your PC and check for any improvements.

8. Temporarily Disable Your Antivirus and Firewall

Try to disable your antivirus to see if that helps fix the error. Antivirus with Internet security features can interfere with your network connection resulting in the default gateway is not available error.

Some antivirus apps allow you to disable the protection temporarily to troubleshoot issues. Disable the antivirus and check if the error is resolved. If yes, turn off Internet security features on your antivirus to determine what's causing the error.

9. Hard Reset Your Router to Its Factory Defaults

While resetting your router can help you fix some internet issues, sometimes, a hard reset is needed to return it to its factory default and resolve any problems with the router configuration. You can factory reset your router using the dedicated reset button or from your router's Web interface.

To reset your router to factory default:

Make sure the router is powered on.

Locate the WSP/Reset button on the front or back of your router. Press and hold the button for at least 10seconds to perform a hard reset. You can use a paper clip or similar objects to access the Reset button.

Release the button after 10 seconds as the LEDs start to flash slowly. Wait for the router to reboot and reset the settings to its factory default.

Reconfigure your router and check if the default gateway is not available error is resolved.

Fix the Default Gateway Is Not Available Error

Most of the time, internet issues can be resolved by running the Network Adapter troubleshooter. If the problem persists, installing pending driver updates and resetting the network drivers and your router can help fix the error on your Windows computer.
