Find Your Ideal Internet Speed
Answer 3 quick questions to see how much speed your home needs.
What Really Uses Up Your Bandwidth
It’s not just streaming videos or downloading games — every smart device connected to your Wi-Fi takes a slice of your bandwidth. Smart TVs, home assistants, security cameras, even automatic software updates all run quietly in the background, consuming data. Knowing how many devices are active (and what they’re doing) helps you size your connection correctly.
Upload vs. Download: The Often-Overlooked Balance
Most people focus on download speed — how fast you can stream or browse — but upload speed matters too. Video calls, online gaming, cloud backups, and remote work tools rely heavily on uploads. If your connection feels laggy on Zoom or during file sharing, the culprit might be limited upload bandwidth.
Why “More Bandwidth” Isn’t Always the Answer
A bigger plan doesn’t always fix slow Internet. Network congestion, outdated routers, or Wi-Fi interference can bottleneck performance even on high-bandwidth connections. Before upgrading, it’s worth checking your home setup — sometimes repositioning your router or switching to wired connections can make a bigger difference than buying more Mbps.
Frequently Asked Questions (FAQs)
What’s the difference between download and upload speed?
Download speed measures how quickly data travels to your device — like when you stream videos, browse websites, or download files.
Upload speed measures how fast data travels from your device — like when you send an email attachment, upload a video, or join a video call.
Both matter: slow uploads can cause lag in meetings or make file sharing painfully slow even if downloads feel fine.
Why does my Internet feel slow even with high Mbps?
A high Mbps plan doesn’t always guarantee a fast experience. Factors like Wi-Fi signal strength, router age, network congestion, or too many devices using the connection at once can bottleneck your speed. Running a speed test or connecting directly via Ethernet can help diagnose whether the slowdown is due to your equipment or your service plan.
How many devices can share my Internet connection?
Every connected device — from smartphones and laptops to smart TVs and IoT gadgets — uses a portion of your bandwidth.
For example, a 100 Mbps connection might handle:
For example, a 100 Mbps connection might handle:
- Light use for up to 6–8 devices, or
- Heavy streaming and gaming for about 3–4 devices.
If your home has more connected tech, you’ll want to choose a plan with higher bandwidth.
What’s a good Internet speed for streaming or gaming?
- HD streaming: ~5–10 Mbps per device
- 4K streaming: ~25 Mbps per device
- Online gaming: ~10–25 Mbps per player
- Video calls: ~3–5 Mbps per user
Remember, these add up. If multiple people are streaming or gaming at once, you’ll need extra bandwidth to keep things smooth.
Does latency affect bandwidth?
Latency and bandwidth are related but not the same. Bandwidth is how much data your connection can carry at once, while latency is how quickly each bit of data travels.
Even with high bandwidth, high latency (lag) can make your connection feel slow — especially in gaming or video conferencing. Lower latency means faster responses and smoother performance.
