✅ The Solution
In this video, you’ll learn how to boost your Wi-Fi signal strength and stability by switching to a high-gain external antenna.
This simple hardware upgrade can dramatically improve your IoT project performance.

🔧 The Modification Process
We’ll walk through a precise hardware mod:
Locate the tiny 0Ω resistor near the IPEX connector
Carefully move it from “Internal” → “External”
Connect your external antenna properly
⚠️ Note: This requires steady hands and a fine soldering tip.

📡 Why This Works
External antennas provide higher gain
Better signal penetration through walls
More reliable streaming for surveillance or robotics projects

🎯 Perfect For:
DIY security cameras
Robotics & FPV projects
Smart home systems
Long-range IoT applications
