How to revive the network without rebooting the PC?

Hong 1,436

I have had to reboot my Windows 11 PC to restore network connectivity every day for the past week or so. The network stops working in 20 to 30 hours after the reboot. When the network stops working, I can access neither the internet nor local devices on the same LAN.

Here is what I have tried:

The built-in Wi-Fi.
External USB Wi-Fi adapter.
Ethernet cable.
Disable Wi-Fi and use Ethernet only.
Disable Ethernet and use Wi-Fi only.
Disable Wi-Fi, then enable and use it.
Disable Ethernet, then enable and use it.
Close all programs.
Network troubleshooter
Check the network connection of a Windows 10 laptop on the same network when the PC has the network issue, and the Windows 10 laptop never has this issue.

Only rebooting the PC guarantees that it will work.

The start of this problem coincided with the installation of KB5068861 (OS Builds 26200.7171 and 26100.7171). Is this a pure coincidence?

Just in case it is relevant, Android Studio shows the following error when the network stops working:

FAILURE: Build failed with an exception.

* What went wrong:

java.net.SocketException: No buffer space available (maximum connections reached?): bind

Could anyone offer a tip on how to resolve this issue?

Hi,

I’m really sorry about the issue you’re running into. Here's what i got a Potential Fixes Without a Full PC Reboot.

While a PC reboot guarantees a temporary fix, the following commands executed in an elevated command prompt might help restore connectivity without a full restart:

Open Command Prompt as Administrator: Right-click the Start button, search for "Command Prompt", right-click it, and select Run as administrator.
Run Network Reset Commands (press Enter after each line):
- netsh winsock reset
- netsh int ip reset
- ipconfig /release
- ipconfig /renew
- ipconfig /flushdns
- ipconfig /registerdns
Disable and Re-enable the Network Adapter via Device Manager to force a reinitialization:
- Right-click the Start button and open Device Manager.
- Expand Network adapters.
- Right-click your specific network adapter (e.g., Realtek, Intel, Mediatek) and select Disable device.
- Wait a few seconds, then right-click the same adapter and select Enable device.

Hopr that this helps.

Kind regards,

Thank you for the tip. I will try it when it happens again (likely tomorrow).

Among the list of 10 things that I have tried, #4, #5, #6, and #7 are related to disabling and enabling as described in my question. If I understand you correctly, the disabling and enabling must be done after running all those commands.

Here is how I did them:

Hi,

Yes, if you follow the commands I provided, the steps you described for disabling and enabling the adapter can be done after running the command-line sequence.

The order is important to ensure a comprehensive network stack reset. The commands reset the Winsock catalog and the IP stack, and flush various caches, which helps clear up underlying issues that a simple disable/enable (as you previously tried) might not address.

Here's why the order matters in this case:

Running the netsh and ipconfig commands first essentially wipes the slate clean for your network configuration, preparing it for a fresh start.
The subsequent disabling and enabling of the adapter via the graphical interface or Device Manager forces the system to re-read and re-apply these newly reset default settings, which is a key part of the process for some issues.

Thank you for the elucidation.

I have just tried your instructions, and it worked without disabling and enabling the adapter.

I will find out which command solves the problem next time by running the commands one by one and checking the connectivity every time.

The problem occurred again minutes later. I tried the instructions again and found the connectivity was restored immediately after the following command:
ipconfig /renewHowever, the problem recurred minutes later. I had to reboot the computer to resolve it.

The above scenario repeated three days later (yesterday): the commands solved the problem, but only for a short period of time. I did enable and disable adapters after running the commands.

I will post another question with more observations and reference this one.
