What Speed Do I Need for Fibre Internet?

Fibre speed is the rate at which data travels between the internet and your home, measured in megabits per second (Mbps). Choosing the right speed means getting a connection that handles everything your household does online without paying for bandwidth you will never use.

Who This Guide Is For

This guide is for you if:

You are signing up for fibre for the first time and don’t know which speed to pick

You are currently on a fibre package but feel like you are paying too much or getting too little

Your household has grown (more devices, more people, more streaming) and you need to figure out whether to upgrade

You are a remote worker or student who needs a reliable connection for video calls and uploads

You just want a straight answer without wading through technical jargon

Whether you are in Joburg, Cape Town, Durban, or anywhere else where Vuma Reach fibre is available, this guide will help you find the right speed for your life.

What Do the Numbers Actually Mean?

When you see a fibre package listed as “50/25Mbps”, those two numbers tell you everything:

The first number (50Mbps) is your download speed, which is how fast stuff comes to you. Streaming Netflix, loading web pages, downloading game updates, pulling files from the cloud.

The second number (25Mbps) is your upload speed, which is how fast stuff goes from you to the internet. Video calls, uploading photos, sending emails with attachments, pushing files to Google Drive.

Symmetrical packages (like 25/25Mbps or 100/100Mbps) give you equal speed in both directions. These are brilliant for remote workers and gamers because you are sending just as much data as you are receiving.

A Quick Reality Check on Speed

Here is something that catches a lot of people out: your internet speed is shared across every device connected to your Wi-Fi. So if your package gives you 50Mbps and three family members are each streaming HD video (which uses about 5-8Mbps per stream), that is already 15-24Mbps spoken for. Add someone downloading a game update and another person on a Zoom call, and suddenly that 50Mbps line is working pretty hard.

That is why picking the right speed is not just about what one person needs. It is about what your whole household needs, all at the same time.

Speed Tiers Explained, With Real-World Examples

Let’s break down what each speed tier actually feels like in day-to-day use. No tech jargon, just the real stuff.

20Mbps (Entry Level)

What it handles: Basic browsing, social media, email, standard-definition streaming on one or two devices, online learning platforms.

Real-world example: You are a student living alone or with one housemate. You attend online lectures on Zoom, browse the web for research, scroll through TikTok and Instagram in the evenings, and occasionally stream a series on Showmax in HD. Everything works fine, as long as you are not trying to do all of it at once while someone else downloads a massive file.

Download a 5GB game update: About 35 minutes

25-30Mbps (Light Use)

What it handles: HD streaming on two to three devices, video calls, browsing, social media, light cloud storage use.

Real-world example: A couple living together. One person is on a Teams call for work while the other streams a cooking show on YouTube. In the evening you both watch Netflix, one on the TV and one on a tablet. It is smooth, there is no buffering, and you are not fighting over bandwidth. This tier is also solid for a small household where nobody is doing anything super data-heavy.

Download a 5GB game update: About 22-27 minutes

50Mbps (Family Sweet Spot)

What it handles: HD and 4K streaming on multiple devices, video conferencing, online gaming, regular downloads, smart home devices.

Real-world example: A family of four. Dad is on a video call in the home office. Mom is streaming a 4K documentary on the TV. One kid is gaming on PlayStation while the other watches YouTube on a phone. The smart doorbell and security cameras are running in the background. Everyone is online, everyone is happy, nobody is shouting “the internet is slow” down the passage.

Download a 5GB game update: About 14 minutes

100Mbps (Power User)

What it handles: Multiple 4K streams, competitive online gaming, large file uploads and downloads, home office with VPN, multiple video calls running at once.

Real-world example: A busy household of four to six people, or a home with a serious remote worker. You have got a developer uploading code to GitHub while running a persistent VPN connection. Two kids are gaming competitively (where every millisecond of lag matters). Someone else is on a video call. The TV is streaming 4K. Game updates that used to take an hour download in about seven minutes. This tier gives you proper breathing room. You almost never notice the connection.

Download a 5GB game update: About 7 minutes

200Mbps (No Limits)

What it handles: Everything. All at once. Without blinking.

Real-world example: A large household or home office setup where multiple people are simultaneously doing bandwidth-heavy work. Think: two remote workers on VPN, a content creator uploading large video files, three kids streaming and gaming, security cameras running, smart home devices everywhere. A 50GB game update downloads in about 35 minutes instead of hours. You will likely never max this line out, and that is exactly the point. It is built for households that refuse to compromise.

Download a 5GB game update: About 3.5 minutes

Household Size Calculator

Use this quick guide to find your starting point based on how many people are regularly online in your home:

Important: These are starting points, not hard rules. If you are a household of two but both of you work from home on video calls all day while downloading large files, bump up to 50Mbps or even 100Mbps. It is about how you use the internet, not just how many people are using it.

Activity Matrix: How Much Speed Does Each Activity Need?

Here is a breakdown of what common online activities actually require. Use this to add up what your household typically does at the same time:

Pro tip: Add up the speeds for everything your household does simultaneously during peak hours (usually 6-9 PM). That total is roughly the minimum speed you should be looking at. Then add a 20-30% buffer, because real-world Wi-Fi is never quite as fast as the line speed.

Package Recommendations

As a general guide, here is how different speed tiers typically line up with common household needs, depending on the number of users, devices and activities in your home. Check our deals page for current packages, pricing and availability. Every Infini-fi package is unlimited and uncapped. No throttling, no data limits, no fair-usage nonsense.

Package prices and available speeds can change depending on the fibre network, promotion and area. Instead of relying on old price examples, use the guide below to estimate the type of speed your household may need, then check the latest Infini-fi fibre deals for current pricing and availability.

• Light browsing, email and basic streaming: start with an entry-level fibre package.
• Small households, video calls and regular streaming: look at balanced mid-range speeds.
• Families, remote workers and gamers: consider higher-speed packages with stronger upload performance.
• Large homes, content creators and heavy multi-device use: compare the higher-speed options on the Deals page.

5 Things to Remember

Your speed is shared across every device in the house. Choose a package that handles your peak-time usage, not just what one person needs.

Upload speed matters more than most people realise, especially for video calls, cloud backups, and working from home. Look for symmetrical packages if this applies to you.

Every Infini-fi package is unlimited and uncapped. No data limits, no throttling, no fair-usage policies, no hidden catches.

Wi-Fi is not the same as fibre speed. Your router, its placement, and the Wi-Fi band you are connected to all affect performance. A slow Wi-Fi experience does not always mean a slow fibre line.

When in doubt, go one tier up. It is better to have a little speed headroom than to constantly feel like your connection is under pressure. The price difference between tiers is usually less than a takeaway coffee per day.

Frequently Asked Questions

1. What is the difference between download speed and upload speed?

Download speed determines how quickly data arrives at your device. Think streaming, browsing, and downloading files. Upload speed is how quickly data leaves your device. Think video calls, uploading photos, and sending large email attachments. Most people need more download than upload, but if you work from home or do video calls regularly, upload speed becomes just as important.

2. Is 25Mbps fast enough to work from home?

For a single remote worker doing video calls and general office tasks, ja, 25Mbps is generally enough. But if there are other people in the house using the internet at the same time (streaming, gaming, downloading) you will want to step up to 50Mbps or higher to avoid that frustrating lag during important calls.

3. Can I stream 4K on a 25Mbps connection?

You can, just. A single 4K stream requires about 25Mbps, so it would use almost all your available bandwidth. That means anything else happening on the network at the same time could cause buffering. If 4K streaming is important to you, we recommend 50Mbps at minimum, or 100Mbps if you want to stream 4K while other people are online too.

4. How many devices can my fibre line handle at once?

There is no hard limit on the number of devices. It is about what those devices are doing. A phone checking WhatsApp messages uses almost no bandwidth, while a TV streaming 4K uses a lot. As a rough guide: on a 50Mbps connection, you can comfortably run 8-10 devices doing light tasks, or 4-5 devices doing heavier tasks like streaming and gaming.

5. Does gaming need fast internet?

Online gaming itself does not use much bandwidth, about 3-6Mbps is enough. What gaming needs is a stable connection with low latency (ping), and fibre delivers exactly that. Where speed really matters for gamers is downloading and updating games, which can be 50-100GB or more. On a 100Mbps line, a 50GB update takes about 70 minutes. On 20Mbps, you are looking at nearly six hours.

6. Why is my actual speed lower than what I am paying for?

A few things can cause this. Your Wi-Fi router might be the bottleneck. Try connecting via ethernet cable to see if that fixes it. Thick walls, distance from the router, and using the slower 2.4GHz band instead of 5GHz all reduce Wi-Fi speeds. The fibre line itself delivers the speed you are paying for to the ONT box. Everything after that depends on your router and home setup. If Wi-Fi is the culprit, our guide to fixing slow Wi-Fi covers all the common causes and fixes.

7. Can I upgrade my Infini-fi package later?

Absolutely. If you start on a lower tier and find you need more speed, you can upgrade your package. There is no penalty for wanting more. We would rather you start where you are comfortable and scale up when you need to. Contact us on 084 555 8858 or visit infinifi.co.za to change your package.

8. What makes fibre better than LTE or 5G for home internet?

Fibre is a dedicated physical line to your home, which means you do not share bandwidth with your neighbours the way you do on mobile networks. This gives you consistent speeds regardless of how many people in your area are online. Fibre also delivers much lower latency than LTE or 5G, which means snappier browsing, smoother video calls, and better gaming. And unlike mobile networks, fibre performance does not drop during peak hours when everyone gets home from work. For a full breakdown of both technologies, see our fibre vs LTE comparison guide.
