WiFi Speed Test

Is your WiFi actually delivering what your ISP plan promises? Most wireless connections lose 30–60% of their rated speed due to interference, distance, and congestion. Our continuous monitor reveals exactly how your WiFi performs over time.

The WiFi Speed Reality Check

Your ISP sells you a plan rated in Megabits per second. But the speed your device actually receives depends on the weakest link in the chain — and for most households, that weakest link is the WiFi connection between your router and your device.

Think of it this way: your ISP delivers water to your house through a large pipe (your internet plan). But inside your house, you're using a garden hose (WiFi) to distribute it. No matter how large the incoming pipe is, the garden hose limits what each device actually receives.

This test helps you see your actual WiFi throughput in real time. Run it from different rooms to map your home's wireless performance. If the numbers are significantly below your plan, the problem is your WiFi setup, not your ISP.

WiFi vs. Ethernet: The Real Difference

WiFi (Wireless)

  • ✕ Half-duplex (can't send and receive simultaneously)
  • ✕ Subject to interference from walls, appliances, neighbors
  • ✕ Speed drops with distance from router
  • ✕ Shared airtime between all connected devices
  • ✓ Convenient, no cables needed

Ethernet (Wired)

  • ✓ Full-duplex (simultaneous send and receive)
  • ✓ Zero wireless interference
  • ✓ Consistent speed regardless of distance
  • ✓ Dedicated bandwidth per device
  • ✕ Requires physical cable routing

5 Ways to Optimize Your WiFi Speed

1

Choose the Right WiFi Channel

In crowded apartments, your neighbors' routers broadcast on the same channels as yours, causing interference. Use a WiFi analyzer app to identify congested channels and switch to a cleaner one. Read our guide on the best WiFi channels for 5GHz and 6GHz.

2

Position Your Router Centrally

WiFi signals radiate outward in all directions. Placing your router in a corner wastes half the signal outside your home. Move it to a central, elevated location for maximum coverage across all rooms.

3

Use 5GHz for Speed-Critical Devices

The 5GHz band offers significantly higher throughput than 2.4GHz, though with shorter range. Connect your gaming PC, work laptop, and streaming TV to 5GHz. Leave IoT devices and smart home gadgets on 2.4GHz.

4

Update Router Firmware

Router manufacturers regularly release firmware updates that fix bugs, patch security vulnerabilities, and improve WiFi performance. Check your router's admin panel monthly, or enable automatic updates if available.

5

Consider a Mesh WiFi System

For homes over 1,500 sq ft, a single router often cannot provide full coverage. Mesh systems use multiple access points to blanket your home with consistent signal. They are far superior to range extenders, which halve your bandwidth.

WiFi Speed Test FAQ

Why is my WiFi slower than my internet plan?
WiFi always delivers less than your plan's rated speed due to overhead from encryption, signal attenuation through walls, interference from neighboring networks, and the half-duplex nature of wireless communication. A 500 Mbps plan on WiFi typically delivers 300–400 Mbps in ideal conditions and can drop to 100–200 Mbps through walls or at distance. For the true speed of your plan, test with an Ethernet cable.
Is WiFi 6 (802.11ax) significantly better for speed?
WiFi 6 offers major improvements: higher throughput (up to 9.6 Gbps theoretical), better multi-device handling through OFDMA, and lower latency via Target Wake Time. In real-world use, WiFi 6 typically delivers 30–50% better throughput than WiFi 5 in a busy household. WiFi 6E (6GHz band) goes further by adding clean, uncongested spectrum.
What is the best location for my WiFi router?
Place your router in a central, elevated position — ideally on a shelf at head height, not on the floor or in a closet. Avoid placing it near microwaves, baby monitors, or Bluetooth devices, as these operate on the same 2.4GHz frequency. Keep it away from metal objects and thick concrete walls. If your home is large, consider a mesh system instead of a range extender.
Should I use 2.4GHz or 5GHz?
Use 5GHz for devices close to the router that need speed (gaming PCs, streaming TVs, work laptops). Use 2.4GHz for devices far from the router or that only need basic connectivity (smart home devices, IoT sensors). 5GHz is faster but has shorter range. 2.4GHz is slower but penetrates walls better.
Does the number of devices affect WiFi speed?
Yes. WiFi is a shared medium — every device on your network takes turns communicating with the router. More devices mean more contention and less available airtime for each device. A household with 30+ connected devices (phones, tablets, smart TVs, IoT) should consider a WiFi 6 router with OFDMA, which allows the router to communicate with multiple devices simultaneously.
