Download speed
Download speed measures how quickly data moves from the internet to your device. Low download speed usually affects streaming, browsing, app downloads, and cloud file access.

Understand your internet speed test results
LizSpeedTest helps you measure internet speed and diagnose unstable network quality. Use this page to understand what each metric means and what to try next.
Upload speed
Upload speed measures how quickly your device sends data out. It matters for video calls, file uploads, live streaming, cloud backups, and remote work tools.
Ping and latency
Ping is the response time between your device and a server. Lower ping usually feels better in online games, calls, and interactive apps.
Jitter and packet loss
Jitter shows how inconsistent your latency is over time. Packet loss shows that some data never arrives. Both can make a connection feel unstable even when Mbps numbers look acceptable.
Quick troubleshooting checklist
Run multiple tests
Test at different times of day to compare congestion patterns and avoid judging the network from a single result.
Check Wi-Fi signal quality
Move closer to the router, reduce obstacles, and compare results between rooms if your signal is weak or inconsistent.
Pause heavy background traffic
Cloud sync, app updates, downloads, or another person streaming video can distort your test results.
Compare servers and connections
Try another test server or compare Wi-Fi versus mobile data to isolate whether the issue is local or upstream.
Why is my speed test slow?
Slow results can come from weak Wi-Fi, network congestion, ISP throttling, overloaded background apps, or distance from the test server. Repeating tests and checking latency patterns usually helps narrow down the cause.
