3. Consistent Speeds for Streaming and Downloads

Wi-Fi speeds can fluctuate based on factors like signal strength, obstacles, and even the time of day (thanks to network congestion). In contrast, a LAN cable offers a stable, consistent connection that ensures:

• Buffer-free streaming, even in 4K or 8K resolution.
• Faster downloads and uploads, ideal for working from home or backing up large files.
• A smoother experience for simultaneous tasks, like gaming while someone else is streaming Netflix.

Think of it like this: Wi-Fi is like a busy public road with varying traffic, while a LAN cable is your own private expressway.

---

4. Shielding Against Interference

Higher-category LAN cables, like CAT6A, CAT7, and CAT8, are designed with advanced shielding to reduce crosstalk (interference between wires) and electromagnetic interference (EMI) from nearby devices. This makes them perfect for environments where stability and reliability are critical, such as:

• Offices with multiple devices connected simultaneously.
• Homes with smart appliances and IoT devices.
• Gaming setups where even a split-second delay can mean victory or defeat.

---
