Why You Need to Test Your Broadband Speed Properly

In Hong Kong, broadband providers love to advertise their plans with "up to" a certain speed. But the speed you actually get at home can be very different from what's on the brochure. Whether you're with HGC, HKBN, SmarTone, CMHK, or Netvigator, regularly testing your internet speed is the first step to making sure you're getting what you pay for.

This guide will show you how to run accurate speed tests, avoid common mistakes, and know when it's time to complain to your ISP.

Best Speed Test Tools for Hong Kong

Not all speed test tools are created equal. Here are our top picks for Hong Kong users:

1. Speedtest by Ookla (speedtest.net)

The most widely used speed test tool globally, with multiple test servers located in Hong Kong. Available as a web app and mobile app, it measures download speed, upload speed, and latency (ping). We recommend selecting the nearest Hong Kong server for the most accurate results.

2. Fast.com (by Netflix)

A clean, simple interface that starts testing automatically when you open the page. Primarily measures download speed, but clicking "Show more info" reveals upload speed and latency. Since it uses Netflix servers, it reflects real-world streaming performance.

3. nPerf

Provides more detailed test reports, including browsing speed and streaming quality scores. It also has local servers in Hong Kong for reliable results.

4. OFCA Broadband Performance Test

The official speed test tool from Hong Kong's Office of the Communications Authority. Results from this tool carry weight if you need to file a formal complaint against your ISP.

Preparing for an Accurate Speed Test

To get reliable results, follow these preparation steps:

• Use a wired connection: Connect your computer directly to the router with an Ethernet (LAN) cable. Wi-Fi introduces too many variables that skew results downward.
• Close other devices and applications: Make sure no other devices are using the network. Close all downloads, streaming apps, and cloud sync services.
• Restart your router: Reboot your router before testing and wait 2-3 minutes for the connection to stabilise.
• Connect directly to the ONT: If possible, bypass your router and connect your computer directly to the Optical Network Terminal. This eliminates any router bottleneck from the equation.

When Is the Best Time to Test?

The time of day significantly impacts your results:

We recommend testing at multiple times throughout the day and averaging the results. If you primarily use the internet in the evening, peak-hour speeds are what truly matter for your experience.

What Does "Up To" Speed Actually Mean?

This is where many subscribers get frustrated. When a provider advertises "up to 1000Mbps," here's what that really means:

• It's the theoretical maximum speed, not a guaranteed speed
• In practice, you'll typically get 70%-90% of the advertised speed
• During peak hours, speeds may drop further
• Shared bandwidth services (common in some housing estates) are affected more

According to OFCA guidelines, if your actual speed consistently falls below 50% of the advertised speed, you have grounds to file a complaint with your provider.

Reasonable Speed Expectations by Plan

Note: Upload speeds are typically the same as download speeds (symmetric fibre), but some budget plans may offer lower upload speeds.

Common Factors That Affect Your Speed

Hardware Factors

• Router performance: Older routers may not handle high-speed connections. If you're on a 1000Mbps plan, make sure your router supports Gigabit LAN ports.
• Ethernet cable quality: Use Cat 5e or higher cables. Older Cat 5 cables max out at 100Mbps.
• Network adapter: Ensure your computer's network card supports the speeds you're paying for.
• Wi-Fi standard: You need Wi-Fi 5 (802.11ac) or Wi-Fi 6 (802.11ax) to take full advantage of fast broadband.

Environmental Factors

• Wi-Fi interference: Neighbouring Wi-Fi networks, microwaves, and Bluetooth devices can all cause interference. This is especially problematic in Hong Kong's densely packed residential buildings.
• Distance from router: Wi-Fi signals weaken significantly when passing through walls.
• Number of connected devices: Multiple household members streaming or downloading simultaneously will divide the available bandwidth.

When Should You Complain to Your ISP?

Consider contacting your provider if:

• Your wired connection speed is consistently below 50% of the advertised speed
• You experience frequent disconnections or unstable connections
• Speeds are abnormally slow even during off-peak hours
• The problem persists for more than 3 days

How to Complain Effectively

1. Document evidence: Run multiple tests at different times and save screenshots (we recommend using the OFCA official tool)
2. Contact ISP support: Provide your test results and request a technician visit
3. Request written confirmation: Note down your complaint reference number and follow-up timeline
4. Escalate to OFCA: If your provider fails to resolve the issue, file a formal complaint with the Office of the Communications Authority
5. Consider switching: If the problem cannot be resolved, it may be time to switch to a different provider

Practical Tips to Boost Your Speed

• Place your router in a central location in your home, away from corners and metal objects
• Use the 5GHz Wi-Fi band for faster speeds (though range is shorter)
• Consider a Mesh Wi-Fi system for better coverage in larger flats
• Regularly update your router's firmware
• If your router is over 3-4 years old, consider upgrading to a newer model

Final Thoughts

Proper speed testing helps you understand whether you're getting value for money. Remember to use a wired connection, test at different times of day, and rule out hardware bottlenecks for the most accurate results. If your speeds consistently fall short, don't hesitate to raise the issue with your provider.
