“Why can other people’s networks access the internet scientifically, filter ads, and control devices globally?”
The answer may not lie in the speed of the internet itself, but in whether your router is smart enough.
This article will guide you step by step on how to upgrade an ordinary home router into a smart soft router hub using OpenWrt, enabling advanced network management, smart home integration, network acceleration, and privacy protection.

🛠️ 2. Flashing OpenWrt: Taking Xiaomi Router as an Example
📥 Obtaining Firmware
Visit OpenWrt.org or the Enshan Forum
Download the stable version firmware (.bin) corresponding to your model
🔄 Flashing Steps (slightly different for different models):
Log in to the factory backend, enter developer mode or enable SSH
Use scp / WinSCP to upload the OpenWrt firmware to /tmp/
After SSH login, execute:
mtd -r write /tmp/your_firmware.bin firmware
After rebooting the router, access the default address:
http://192.168.1.1 Username: root / Password: (leave blank)
🧩 3. Installing Common Plugins (The Soul of OpenWrt)
🔧 Plugin Management:
Enter the Web management backend LuCI → System → Software Packages
⭐ Recommended Common Useful Plugins:
|

🔐 4. Advanced Play: OpenWrt Gives You Carrier-Level Network Experience
📡 Multi-connection Speed Boost & Bandwidth Aggregation
The multi-connection tool (MWAN3) can achieve “1 broadband connection dialed 3 times”, aggregating bandwidth to improve download speeds (effective in some regions)
🌍 Scientific Internet Access Traffic Splitting
Only allow specific devices (like Apple TV) or websites to go through the proxy, while others connect directly → Save node resources
🎯 Home Traffic Control + Device Speed Limiting
Precise speed control down to device MAC or IP, ensuring the main computer/TV does not lag
Can set sleep periods to disconnect the internet/block internet periods, a tool to prevent addiction
🎞️ Home Audio-Video Center
Router connected to a mobile hard drive + Samba/NFS → Create a lightweight NAS
Used with Kodi / Jellyfin clients for streaming high-definition video
🧱 5. Building the “Brain of the Home Network” with OpenWrt
Once you become familiar with OpenWrt, it is no longer just “router firmware”; it becomes your:
✅ Ad Blocker (AdGuard)
✅ Smart Home Hub (integrating Home Assistant)
✅ Private Cloud Access Point (mapping Synology/Nextcloud)
✅ Remote Access Jump Point (Tailscale / Zerotier)
✅ Anonymous Network Proxy (Tor / Shadowsocks)
✅ IoT Traffic Isolation Firewall (guest/smart device VLAN separation)
Truly achieving a “whole-house network center + privacy control hub”.
📈 Who is suitable for getting into OpenWrt?
🧑💻 Tech enthusiasts who love tinkering with devices
👨👩👧👦 Parents wanting to create a “smart network” for their family
🧳 People who travel frequently/remote workers
🎮 Gamers & audio-visual enthusiasts
🌐 Geeks pursuing privacy and security
✅ In summary: OpenWrt is the key to “intelligentizing cheap routers”
Don’t think that home networking is just about “plugging in to get online”; true network optimization starts with router intelligence. OpenWrt is not just about “flashing a system”; it allows you to achieve carrier-level network experience + data security + smart home control at a very low cost.
