How to Get a Stronger WiFi Signal

On February 16, 2025 By newsroom Topic: Technology Buyers Guide

Before Buying a New Router

Check Your Broadband Speed: - Use tools like Fast.com to verify your internet speed. A 15 Mbps connection is needed for 4K streaming.
- Test speeds in different home areas with a wired and wireless connection.

Router Placement: - Place the router centrally to maximize signal reach. Avoid basements or closets.
- Use a long Ethernet cable to reposition your router if necessary.

Understand Interference: - Thick walls, metal appliances, and water (e.g., fish tanks) can block signals. Adjust placement to mitigate these obstacles.
- Switch to less congested bands (5GHz or 6GHz) if nearby devices are on 2.4GHz.


Types of WiFi Solutions

Traditional Routers: - Affordable and support many devices.
- May struggle in large or multi-story homes.

Mesh Routers: - Multiple units create a seamless network, eliminating dead zones.
- Best for large homes but can be expensive ($100–$1,000).

WiFi Extenders: - Cost-effective (as low as $20) for addressing single dead spots.
- Less effective than mesh systems but useful for minor fixes.


Common WiFi Roadblocks

Walls: - Thick or metal-reinforced walls weaken signals. Place routers or satellites strategically.

Appliances: - Metal-heavy appliances like refrigerators can reflect signals. Keep routers away from them.

Neighbors’ WiFi: - Wireless congestion in apartments can interfere. Use 5GHz or 6GHz bands to reduce interference.

Microwaves: - Operate on the 2.4GHz band and may disrupt connections. Switch devices to 5GHz while microwaving.

Water: - Fish tanks or plumbing absorb WiFi signals. Keep routers distant from these.


Product Recommendations

  • Traditional Routers: Ideal for small homes or simpler setups.
  • Mesh Networks: Best for large homes or challenging layouts. Options start at $100.
  • WiFi Extenders: Affordable choice for eliminating small dead zones.

By identifying obstacles and optimizing placement, you can maximize your existing WiFi setup before considering a costly upgrade.
