สายเคเบิลที่ดีที่สุดสำหรับเครือข่ายในบ้าน

## Quick Decision Matrix

| Your Speed | Cable | Why |
|---|---|---|
| Up to 1 Gbps | Cat5e | Cheapest, works fine |
| 2.5 Gbps | Cat5e or Cat6 | Cat5e works short runs |
| 5-10 Gbps | Cat6a | Required for reliable 10G |
| Future-proof | Cat6a | Best value for new installs |

## In-Wall Installation

If you're running cable through walls, **always use Cat6a**:
- Only marginally more expensive than Cat6
- Supports 10 Gbps at full 100m distance
- Lasts 20+ years in-wall
- Use solid-core (not stranded) for permanent runs

## Patch Cables (Device to Wall/Switch)

- **Cat6 or Cat6a stranded**: Flexible, for short desk runs
- **Flat cables**: Great for under-carpet or along baseboards
- **Slim cables**: 28AWG for tight spaces (fine for short runs)

## Networking Equipment to Match

- **2.5G switch**: TP-Link TL-SG105-M2 (~$50)
- **2.5G NAS**: Synology DS224+ with 2.5G port
- **2.5G USB adapter**: USB-C to 2.5G Ethernet (~$15)
