Staff Flush DNS and Reset TCP/IP Stack

[Luckyy]

if you're having issues with slow internet, DNS errors, or websites not loading, flushing your DNS cache and resetting your TCP/IP stack can help resolve many network problems quickly.#​

Flush the DNS Cache​

1. Press Win + S and search for cmd
2. Right-click Command Prompt → Select Run as administrator
3. Run this command:

ipconfig /flushdns

You should see:

Successfully flushed the DNS Resolver Cache.

This clears out old or incorrect domain info stored on your PC.

Reset TCP/IP Stack​

Still having issues? Reset the TCP/IP stack:

1. In the same Command Prompt, type each of these and press Enter:

netsh int ip reset

This command resets all TCP/IP settings to default.

2. Also reset the Winsock catalog (socket connections):

netsh winsock reset

3. Restart your computer to complete the reset.

Optional: Release & Renew IP + Clear DNS Cache​

These additional commands can help:

ipconfig /release

ipconfig /renew

ipconfig /registerdns

Use these if your IP address isn't renewing or you're getting "No Internet" errors.

When to Use These Fixes​

• Can't connect to certain websites
• Internet works on phone but not PC
• DNS_PROBE_FINISHED errors
• Changes to DNS settings aren't working
• Router/modem reset but issues persist

Tip: If you're still having issues, try switching to public DNS like 1.1.1.1 or 8.8.8.8 in your adapter settings.

You're all set! This should fix most DNS and local network issues on Windows.
