Default gateway repeatedly isn't available

Question

Several times each day my home PC stops connecting to the internet. The ethernet port is labelled as "no connection" and apps stop working.

Luckily, the Windows troubleshooter for "Network Adapter" is able to resolve the issue by resetting the ethernet adapter.

Unfortunately, running the troubleshooter doesn't permanently fix the problem. Some time will go by and the same thing will happen again.

The troubleshooter lists the issue fixed as "The default gateway is not available", which may indicate an issue with my router. No other devices on my network have the issue, it's just my PC.

I'm using Windows Dev (OS Build 21327.1000).

How can I permanently solve the issue?

Good day! I'm Raniel, an Independent Advisor and a Microsoft user like you.

Have you also tried to double-check if your machine doesn't have any pending security patches? Kindly go to Start > Settings > Update & Security > Windows Update > Check for Updates.

Once done, reset of your DNS cache and reinstall your network adapter to troubleshoot the issue:

1. On the search bar, type "command prompt" and select Run as administrator
2. Type the following commands and press Enter after each command

ipconfig /flushdns

nbtstat -R

nbtstat -RR

netsh int reset all

netsh int ip reset

netsh winsock reset

3. Once done, type "devmgmt. msc" on the command prompt window to open Device Manager
4. Expand Network adapters > right click on your network adapter and select Uninstall device > the Delete the driver software for this device check box > Uninstall.
5. Perform a reboot(this should reinstall your network adapter).
6. Temporarily disable your firewall and antivirus, then check again

I hope this helps. Good luck!

Answer 2

Unfortunately this didn't solve my issue. Also, the command

netsh int reset all

Didn't work:

The following command was not found: int reset all.

Answer 3

Are the instructions any different for an ethernet network adapter instead of a wireless one?

Hi PizzaFox,

Apologies if the suggested steps didn't work for you.

Can you also perform the additional steps on this article: https://appuals.com/default-gateway-is-not-avai....

However, if the issue still persist, kindly perform a repair install of you Windows. I suggest that you watch the video on this article(https://www.tenforums.com/tutorials/16397-repai... or https://www.yourwindowsguide.com/2016/06/how-to...) for you to have an idea regarding the process of repair install. There should be no worries in performing it since you will select the option to keep your files during the process.

You may also look into the Windows 10 recovery options (system restore or reset). Please see this article for details: https://support.microsoft.com/help/12415/window...

Please let me know how it goes. Thank you.
