About Guide
The Internet Speed Guide explains what download, upload, ping (latency), and jitter mean on a speed test — and what counts as a good result for streaming, gaming, video calls, and working from home.
Use this guide with a live speed test on SpeedTesters: measure first, then interpret the numbers here. Speeds vary by WiFi vs Ethernet, time of day, and how many devices share the connection.
After you understand the basics, open the related guides for gaming, streaming, mobile data, WiFi vs Ethernet, and step-by-step fixes for slow internet.
How to use
- Skim the Guide for the metric you care about (ping, download, or upload).
- Run a free speed test on the homepage for live numbers.
- Open a related guide or the FAQ if results look lower than your plan.
Limits & notes
- Results are estimates and can vary with WiFi, congestion, VPN, and time of day.
- Works in modern browsers on desktop and mobile; no app install required.
- For a clean baseline, prefer Ethernet and close background downloads before testing.

Frequently asked questions
How much internet speed do I need?
A single user browsing and streaming HD is fine on 10–25 Mbps. For 4K streaming, video calls, and multiple devices, aim for 50–200 Mbps. Large households, frequent large downloads, or heavy work-from-home setups benefit from 300 Mbps to 1 Gbps.
What is the difference between Mbps and MBps?
Mbps (megabits per second) measures connection speed, while MBps (megabytes per second) measures file-transfer/download size. There are 8 bits in a byte, so a 100 Mbps connection downloads at roughly 12.5 MBps. Internet plans are advertised in Mbps.
What is a good ping for gaming?
For online gaming, lower ping is better. Under 20 ms is excellent, 20–50 ms is good, 50–100 ms is playable, and over 100 ms can cause noticeable lag. A wired Ethernet connection usually gives the lowest, most stable ping.
How do I fix slow WiFi?
Move closer to the router or reduce walls between you and it, switch to the 5 GHz band, restart the router, update firmware, avoid interference from other devices, and use Ethernet or a mesh system for problem areas. Then re-run a speed test to confirm the improvement.
Is a wired (Ethernet) connection faster than WiFi?
Usually yes. Ethernet delivers more consistent speeds and lower ping because it avoids wireless interference and signal loss. For the most accurate speed test and best gaming performance, connect directly with a cable.
