How to Test Internet Speed Accurately
Speed tests are easy to misread. A slow result might mean your ISP is throttling — or that your microwave is killing your Wi-Fi. Here's how to test properly.
What the Numbers Mean
- Download — how fast you receive data (streaming, browsing)
- Upload — how fast you send data (video calls, uploads)
- Ping/latency — round-trip time in ms (lower is better)
- Jitter — variation in ping (matters for calls and gaming)

Test My SpeedHow to Test Accurately
- Use Ethernet, not Wi-Fi, when possible
- Close streaming, downloads and cloud sync first
- Test 3 times at different times of day
- Compare against your ISP's advertised speed
Common Speed Killers
- Old router (3+ years)
- Wi-Fi interference from other networks
- Too many devices on the same network
- VPN or background updates
When to Call Your ISP
If you consistently get less than 50% of your advertised speed on Ethernet at off-peak hours, your ISP owes you an explanation.
Frequently Asked Questions
Why is my Wi-Fi speed slower than my Ethernet speed?+
Wi-Fi shares the airwaves with neighboring networks, walls, and household electronics like microwaves. Ethernet delivers a dedicated, interference-free connection to your router.
Does using a VPN affect speed test results?+
Yes — VPNs add encryption overhead and route traffic through a remote server. Expect a 5–20% drop in speed depending on the server's distance and load.
What is a good ping and jitter for gaming?+
For competitive gaming, aim for ping under 30 ms and jitter under 5 ms. Anything above 100 ms introduces noticeable lag in fast-paced games.
Why does my speed test show faster results at 3 AM than 8 PM?+
Network congestion. Your ISP's infrastructure handles peak evening traffic from thousands of users simultaneously, which can temporarily reduce available bandwidth.
