Why Is Your Fixed Internet Slow? Common Causes & How to Speed It Up
That spinning loading wheel during your favourite series. A video call freezing just as you start speaking. You’re paying for a high-speed plan, yet your fixed internet feels anything but fast. It’s a common frustration across Portugal.
Before blaming your provider, it’s important to understand that slow performance is often caused by in-home Wi-Fi setup, device overload, or bandwidth limits — not the fibre line itself. In this guide, we’ll help you diagnose the real issue and show you how to fix it properly.
- Run a proper speed test (wired vs Wi-Fi) before assuming your provider is at fault.
- Router placement and mesh Wi-Fi can dramatically improve performance.
- Your current bandwidth may not match your household’s streaming and gaming demands.
- Upgrading to high-performance fibre (up to 1 Gbps) can future-proof your home.
Step 1: Diagnose the Problem Properly
Start simple: reboot your router and modem. Wait 30 seconds before turning them back on. This clears temporary glitches and often restores performance.
Run a Wired Speed Test
Connect a laptop directly to your router using an Ethernet cable and run a speed test. This shows the real speed entering your home.
- Download speed – important for streaming and browsing.
- Upload speed – crucial for video calls and remote work.
- Latency (ping) – vital for gaming and live communication.
If wired speeds are good but Wi-Fi is slow, the issue is your internal network, not your fibre connection.
Step 2: Optimise Your Home Wi-Fi
Router Placement Matters
Place your router centrally, elevated, and away from thick walls or large appliances. Portuguese homes — especially Algarve villas — often have concrete construction that blocks signal.
Use the Right Frequency
- 2.4 GHz – wider coverage, slower speeds.
- 5 GHz – faster speeds, shorter range.
Consider Mesh Wi-Fi
If you experience dead zones, one router may not be enough. A mesh Wi-Fi system creates a seamless network across your entire home.
Lazer Telecom Smart Internet includes advanced whole-home Wi-Fi solutions powered by eero mesh technology, designed specifically for larger properties and multi-device households in the Algarve.

Step 3: Check If Your Plan Is the Bottleneck
Modern households demand more bandwidth than ever:
- 4K streaming on multiple TVs
- Online gaming
- Remote working with VPN
- Cloud backups and smart home devices
If multiple users are online simultaneously, lower-tier plans may struggle. Upgrading to high-performance fibre — especially symmetrical speeds — ensures smoother streaming and reliable uploads.
Lazer Telecom offers fibre packages up to 1 Gbps, with options including Fixed IP and VPN support for business and remote professionals.
Step 4: When to Contact Your Provider
Contact your ISP if:
- Wired speeds are significantly below your contracted plan.
- You experience frequent disconnections.
- Latency spikes persist even on Ethernet.
Choosing a provider with local, English-speaking support can make troubleshooting far less stressful.

Frequently Asked Questions
Why is my internet fast on Ethernet but slow on Wi-Fi?
This usually indicates signal interference or poor router placement. A mesh Wi-Fi system can resolve coverage issues.
How do I know if I need a faster fibre plan?
If multiple devices stream, game or video-conference simultaneously and performance drops, you may need higher bandwidth.
Is fibre more reliable than older connections?
Yes. Fibre optic connections are more stable, resistant to interference, and capable of much higher speeds than copper-based services.
