Why Is My Internet So Slow at Home? (And How to Fix It Without Calling a Technician)

You're working from home, trying to join a Zoom call or stream a movie—and everything buffers. Again. You’ve paid for high-speed internet, but it feels like you’re using dial-up. If you're dealing with slow internet at home, you're not alone.

As a trusted IT support provider in Melbourne, we get this question every week. Here's a simple, jargon-free guide to help you troubleshoot and speed up your connection—before you even think about calling your ISP or an IT technician.

Common causes of slow internet at home, with router and devices shown visually

Common Reasons for Slow Internet at home(with Real-Life Fixes)


1. Too Many Devices Using the Same Network


Real-life example: Your kids are on YouTube, your partner’s watching Netflix, and you're trying to work on a video call. That’s three heavy users at once.


What to do:

  • Disconnect unused devices like tablets or smart TVs not in use.

  • Set limits on video quality (like 480p for YouTube on mobile).

  • Consider upgrading your internet plan if this is a daily issue.

2. Your Wi-Fi Router Is in the Wrong Spot


Real-life example: Your router is tucked behind the TV, in a cupboard, or near a thick brick wall. Wi-Fi hates that.


What to do:

  • Place your router in an open, central spot—ideally eye-level.

  • Avoid corners, metal surfaces, or appliances like microwaves.

  • If needed, invest in a Wi-Fi extender or mesh network.


3. Your Router Is Outdated


Real-life example: You're using a router your ISP gave you 6 years ago. Technology—and speed—have changed.


What to do:

  • Upgrade to a modern dual-band or tri-band router (supports more devices and stronger signal).

  • Look for models that support Wi-Fi 5 (802.11ac) or Wi-Fi 6.


4. You’re Using Too Much Bandwidth Without Realising It


Real-life example: Your PC is syncing to Google Drive and Windows is downloading updates—while you’re trying to stream music.


What to do:

  • Pause cloud syncs or software updates during work hours.

  • Turn off auto-play for videos on websites and social media.


5. You May Have Malware or Background Apps Eating Bandwidth


Real-life example: That slow internet may not be the internet—it might be hidden apps or viruses draining your speed.


What to do:

  • Run a malware scan using tools like Malwarebytes (free version is fine).

  • Check for background apps using Task Manager (Windows) or Activity Monitor (Mac).
