How to Test Your Wi-Fi Strength (And Fix Weak Spots) 

 

Struggling with Wi-Fi in Certain Rooms? 

 

You’ve got fast fibre internet - but somehow, the signal drops when you move to the other side of the house. Buffering in the bedroom? Glitchy video calls in the study? You're not imagining it - Wi-Fi signal strength does vary from room to room. 

Good news: it’s easy to test your Wi-Fi strength, spot the weak spots, and fix them - no tech degree needed. 

Here’s how. 

 

Step 1: Test Your Signal Strength 

Let’s start with the basics - how strong is your Wi-Fi in different parts of your home? 

✅ Use the MetroFibre App (Recommended) 

The newly upgraded MetroFibre App makes this super simple with built-in smart tools: 

  • Self-Test: Run a quick check on your fibre line and Wi-Fi performance. 
  • Wi-Fi Walking Survey: Walk around your home and get real-time feedback on where the signal is strong, weak, or missing altogether. 

It’s like a signal heatmap for your house - right on your phone. 

📲 If you haven’t downloaded the app yet, search “MetroFibre” in your app store (Android: Google Play Store or Apple: App Store) and take it for a spin. 

 

Step 2: Know the Warning Signs of Weak Wi-Fi 

You might be dealing with a Wi-Fi weak spot if you notice any of these: 

  • Websites or apps load slower in certain rooms 
  • Video calls freeze or drop 
  • Streaming quality drops from HD to grainy 
  • Downloads crawl in parts of your home 

This doesn’t necessarily mean your fibre is slow - it means the Wi-Fi signal from your router isn’t reaching everywhere evenly. 

 

Step 3: Fix the Weak Spots Without Moving Your Router 

 

We get it - you can't just pick up and move your router. That’s why these solutions don’t require you to. 

📡 Add a Wi-Fi Extender or Mesh System 

These devices pick up your router’s signal and boost it into the hard-to-reach corners of your home. Mesh systems are especially useful for double-storey homes or larger layouts. 

🔄 Need a premium mesh solution? 

MetroX is our top-tier Wi-Fi mesh system that gives you seamless whole-home coverage. Powered by the Nokia Beacon 2 device, it’s professionally installed by a MetroFibre technician, supports multiple devices without slowing down, and even lets you set up a secure guest network. Available from R99/month per unit, with no long-term contracts, free support, and easy upgrades if you need more coverage later (only available to customers on packages from 150Mbps and Up).

📲 Use the MetroFibre App for Guided Support 

Can’t figure it out? The Assisted Support feature in the app connects you with a MetroFibre technician who can guide you remotely - no need to book a callout or wait for someone to show up. 

💡 Minimise Interference 

While you can’t always change where your router is, avoid placing things like microwaves, baby monitors, or large metal objects near it if possible - these can mess with the signal. 

 

Step 4: Check If You Need More Speed 

 

Sometimes, Wi-Fi weak spots aren’t just about signal - they’re about bandwidth. If more people are online or your streaming and work habits have changed, your current speed might not be cutting it anymore. 

For example: 
If you’re on a 50 Mbps line and you’ve got a family of four all streaming, gaming, or on Zoom calls at the same time, your connection can start to feel sluggish - especially further away from the router. 
Upgrading to a 250 Mbps package means each device gets more speed, making everything feel faster and more reliable - even in rooms with average signal strength. 

Already with MetroFibre? Email orders@metrofibre.co.za with the subject “Upgrade” and we’ll help you find the right plan for your home (upgrades take +- 3 days to action). 

 

MetroFibre Tip: 

You don’t need to be a tech expert to fix Wi-Fi issues - you just need the right tools. Our updated MetroFibre App is designed to give you control, clarity, and quick fixes without the stress. 

Stay Connected, No Matter Where You Are in the House 

You’ve got the fibre. Now make sure your Wi-Fi keeps up - in every room. Whether you’re bingeing shows, running a business, or just scrolling in bed, don’t settle for patchy signal or slow speeds.
