🤔 DIY vs Professional – What’s Best for Your Situation?
✅ DIY Makes Sense When
- Small home or apartment (under 100m²)
- Single, simple dead zone
- You’re comfortable with basic configuration
- No outdoor or complex requirements
- Budget is very tight
👨🔧 Professional Makes Sense When
- Large home or estate
- Thick walls (Pretoria)
- High-density area (Sandton, Fourways)
- Outdoor coverage needed
- Multiple buildings to connect
- You’ve tried DIY and it failed
- You want guaranteed results
Many Gauteng homeowners find that professional installation saves time, frustration, and ultimately money by getting it right first time.
❌ 8 Common Gauteng WiFi Mistakes
Local homeowners often make these mistakes:
- Mistake #1: Buying a cheap extender for a large Pretoria home. Budget extenders lack power for thick walls – invest in RE650 or similar.
- Mistake #2: Placing extender in the dead zone. Common error – extender needs good signal from router, place it halfway.
- Mistake #3: Ignoring channel congestion in Sandton. In dense areas, default channels are overcrowded – professional channel planning needed.
- Mistake #4: Using indoor extenders outdoors. Rain destroys them – use proper weatherproof equipment.
- Mistake #5: Attempting DIY point-to-point without line of sight. Trees or buildings in the way = failure. Professional survey first.
- Mistake #6: Not considering mesh for whole-home coverage. For large properties, mesh often outperforms multiple extenders.
- Mistake #7: Forgetting about Ethernet backhaul opportunities. If you can run cable during renovations, do it – best performance.
- Mistake #8: Not testing placement before permanent mounting. Always test signal before drilling holes.
Avoid these with professional site surveys and installation.
