When you run an internet speed test, you get three numbers: download speed, upload speed, and ping. But what do they actually mean for your daily internet experience? And how do you know if your speeds are good, bad, or just average? This guide breaks it all down.
Download Speed
Download speed measures how fast data travels from the internet to your device, expressed in Megabits per second (Mbps). This is the metric most people care about, because the vast majority of internet activity involves downloading: loading web pages, streaming video, receiving emails, downloading files.
What Download Speed Do You Need?
- 1–5 Mbps — Basic web browsing and standard-definition video streaming. Struggles with HD video or multiple users.
- 10–25 Mbps — Comfortable HD streaming, video calls, and light gaming for 1–2 users simultaneously.
- 50–100 Mbps — Excellent for 4K streaming, fast file downloads, and multiple simultaneous users.
- 200+ Mbps — Future-proof for a busy household or home office with many connected devices.
- 1 Gbps (1000 Mbps) — Gigabit fibre, the current premium tier. Effectively eliminates download speed as a bottleneck.
Upload Speed
Upload speed measures how fast data travels from your device to the internet. Traditionally, residential plans heavily favour download speed (10:1 or even 20:1 ratios were common with ADSL). This made sense when most users primarily consumed content.
Today, upload speed matters far more:
- Video calls (Zoom, Teams, Google Meet) require solid upload speeds — typically 1.5–3 Mbps for HD quality.
- Live streaming on Twitch or YouTube demands 5–10 Mbps sustained upload for 1080p.
- Remote work with file sharing, cloud syncing (Dropbox, Google Drive, OneDrive), and collaborative tools all consume upload bandwidth.
- Online gaming — while individual game packets are small, high upload bandwidth reduces lag when multiple devices are sharing the connection.
Fibre optic connections typically offer symmetrical speeds (same download and upload). Cable and DSL connections tend to have significantly lower upload than download speeds.
Ping (Latency)
Ping, also called latency, measures the time it takes for a small data packet to travel from your device to a server and back, expressed in milliseconds (ms). Lower is always better.
Understanding Ping Values
- <20 ms — Excellent. Virtually no perceptible delay. Ideal for competitive gaming and real-time applications.
- 20–60 ms — Good. Normal for most broadband connections. Suitable for all online activities.
- 60–120 ms — Average. Acceptable for most uses but may introduce slight delays in video calls and gaming.
- 120–250 ms — High. Noticeable lag in games and video calls. Often caused by long physical distances or network congestion.
- >250 ms — Very high. Significantly degrades real-time applications. Unacceptable for gaming and problematic for video calls.
Jitter
Jitter is the variation in ping over time. If your ping is consistently 30ms, that is good. If it fluctuates between 10ms and 80ms, that is high jitter — and it causes problems even if the average is acceptable.
High jitter causes:
- Choppy or freezing video in video calls
- Erratic gameplay in online games
- Audio glitches in VoIP calls
Jitter above 30ms is generally considered problematic for real-time applications. Wired ethernet connections almost always have lower jitter than Wi-Fi.
Why Your Speed Test Result May Not Match Your Plan
You pay for 500 Mbps, but your speed test shows 180 Mbps. Why? Several factors reduce real-world throughput:
Wi-Fi Overhead and Interference
Wi-Fi introduces overhead, interference from neighbouring networks, and signal loss through walls. A device on Wi-Fi in another room may achieve 30–50% of the speed a wired device gets. Always test with an ethernet cable to see your true connection speed.
Network Congestion
ISPs share bandwidth among users in your neighbourhood ("contention ratio"). During peak hours (evenings and weekends), shared infrastructure gets congested and speeds drop.
Speed Test Server Location
Different speed test servers give different results depending on their distance from you and their own network capacity. Our speed test uses Cloudflare's global infrastructure for consistent, reliable measurements.
VPN Overhead
Using a VPN encrypts your traffic, which adds processing overhead and routing through additional servers. Expect 10–30% speed reduction with most VPNs; high-quality VPNs using WireGuard typically reduce speed by less than 10%.
Router and Modem Age
Older routers may not support the throughput your plan offers. A router bought before 2018 may bottleneck a modern gigabit connection.
How to Improve Your Internet Speed
Use Ethernet Instead of Wi-Fi
The single most effective change for most people. A CAT6 ethernet cable delivers your ISP's full speed with near-zero jitter.
Restart Your Router and Modem
Routers can develop memory leaks and routing table issues over time. A monthly restart often improves performance.
Check for Background Processes
Software updates, cloud backups, and streaming services running in the background consume bandwidth without you noticing. Check your device's network usage monitor to identify bandwidth hogs.
Upgrade Your Router
If you have a router more than 3–4 years old, consider upgrading to a modern Wi-Fi 6 (802.11ax) or Wi-Fi 6E router for significantly better throughput and lower latency on wireless connections.
Consider a Mesh Network
In larger homes, a single router creates dead zones and signal degradation. A mesh Wi-Fi system (like Google Nest, Eero, or Asus ZenWiFi) creates a unified network with consistent coverage throughout.
What "Mbps" Actually Means for Downloads
Speed tests report in Megabits per second (Mbps), but file sizes are reported in Megabytes (MB). There are 8 bits in a byte, so divide your Mbps speed by 8 to get your approximate download speed in MB/s.
- 100 Mbps ÷ 8 = ~12.5 MB/s download speed
- 500 Mbps ÷ 8 = ~62.5 MB/s download speed
- 1000 Mbps (1 Gbps) ÷ 8 = ~125 MB/s download speed

Conclusion
Download speed, upload speed, and ping each affect your internet experience in different ways. For most households, 50–100 Mbps download with low latency is more than sufficient. What matters most depends on how you use the internet: gamers should prioritise ping, streamers need upload speed, and remote workers need both reliable upload and low jitter.
The best way to know where you stand is to test. Run our speed test at different times of day to understand your connection's real performance — not just the peak numbers your ISP markets.
