Boost Internet Speed Instantly with 5 Powerful Command Prompt Tricks

**Slow internet** can be triggered by outdated configurations, IP conflicts, cache corruption, or **ISP throttling**. These **five advanced Command Prompt commands** form a **hidden Windows optimization toolkit** to restore and even **supercharge your network performance** —without installing extra software.

* * *

**Preparation – Run as Administrator**  
Before executing these tweaks, **open Command Prompt with admin rights** :

1. Press **Windows key** → type `cmd`.
2. **Right-click** Command Prompt → select **Run as administrator**.
3. Confirm the prompt to enable elevated privileges.

* * *

**1. Renew IP Address**  
Eliminate **IP conflicts** or **DHCP lease issues** that slow connections. Run:

```auto
ipconfig /release
ipconfig /renew

```

✔ Forces a fresh connection handshake with the network.  
✔ Resolves hidden miscommunication with the router.

* * *

**2. Flush DNS Resolver Cache**  
A corrupted DNS cache means slower lookups. Reset instantly:

```auto
ipconfig /flushdns

```

✔ Improves first-time site loading speed.  
✔ Removes outdated or poisoned DNS entries.

* * *

**3. Reset Winsock**  
Damaged **network sockets** or malicious LSPs can hijack or slow traffic. Fix it with:

```auto
netsh winsock reset

```

✔ Restores original socket configuration.  
✔ Essential after malware removal or network errors.  
Restart your PC for changes to apply.

* * *

**4. Optimize TCP Settings with Netsh**  
Fine-tune **TCP/IP parameters** for faster data transfer, lower latency, and smoother connections:

```auto
netsh int tcp set global chimney=enabled
netsh int tcp set global autotuninglevel=normal
netsh int tcp set supplemental
netsh int tcp set global dca=enabled
netsh int tcp set global netdma=enabled
netsh int tcp set global ecncapability=enabled
netsh int tcp set global congestionprovider=ctcp

```

✔ Enables advanced data offloading to hardware.  
✔ Improves large file downloads and streaming.  
_To revert any change, replace_ `enabled` _with_ `disabled`.

* * *

**5. Stop ISP Video Throttling**  
Block **known throttling IP ranges** to maintain streaming quality:

```auto
netsh advfirewall firewall add rule name="StopThrottling" dir=in action=block remoteip=173.194.55.0/24,206.111.0.0/16 enable=yes

```

✔ Prevents intentional slowdowns during video playback.  
✔ Useful for YouTube, Netflix, and other streaming platforms.

* * *

**Extra Pro Tips**

- **Combine with router reboot** for a total connection refresh.
- **Update network drivers** for compatibility with TCP enhancements.
- **Test speeds** before and after with [speedtest.net](https://www.speedtest.net/) to measure improvement.
- Use alongside **Google DNS** (`8.8.8.8` / `8.8.4.4`) or **Cloudflare DNS** (`1.1.1.1`) for better routing.

* * *

These **administrator-level Command Prompt commands** solve most unexplained internet slowdowns, site loading delays, and video buffering. Run them periodically to keep your network operating at peak performance.

* * *

Happy learning!
