Run Network Troubleshooting Commands in Windows 11 and Windows 10 Using netsh and ipconfig

If you cannot access email, browse the web, or stream music on Windows 11 or Windows 10, official Microsoft troubleshooting guidance suggests running a specific sequence of network commands. These commands attempt to manually reset the TCP/IP stack, release and renew your IP address, and flush and reset the DNS client resolver cache.

How to Open an Elevated Command Prompt

To run these network commands, open Command Prompt as an administrator:

1. Select Search on the taskbar and type command prompt.
2. To the right of the Command Prompt button, select Run as administrator.
3. Select Yes at the prompt.

Supported Command Sequence

At the command prompt, run the following commands in the listed order, and then check to see if that fixes your connection problem:

1. netsh winsock reset
2. netsh int ip reset
3. ipconfig /release
4. ipconfig /renew
5. ipconfig /flushdns

Press Enter after typing each command.

Additional Diagnostic Steps

If the command sequence does not resolve the issue, Microsoft documents additional diagnostic checks:

• Check your IP address: Check your IP address to verify it is not an address such as 169.254.x.x. An address formatted like that indicates Windows could not obtain an IP address from your router. If you do not use static IP addresses, verify DHCP is enabled on your router.
• Ping the default gateway: Run ipconfig in an administrative command prompt, locate the IP address listed next to Default gateway for your network (for example, 192.168.1.1), and run ping <DefaultGateway>. A reply indicates a working connection to your router, pointing to a potential modem or ISP issue.
• Check DNS server connectivity: In an administrative command prompt, run ipconfig /all | findstr /c:"DNS Servers" to view the listed DNS server address, then run ping [DNS server address]. If you have a valid IP address but cannot ping your DNS server, Microsoft notes you can change to a different DNS server address.

Network Reset as a Last Resort

Microsoft advises that using network reset should be the last step you try if earlier steps do not help you get connected. Network reset removes installed network adapters and their settings. After your PC restarts, network adapters are reinstalled with default settings. Microsoft notes that after using network reset, you may need to reinstall and configure other networking software, such as VPN client software or virtual switches from Hyper-V, and known connections may be set to a public network profile.
