Why does internet speed vary?
Understand why each test gives a different number and when variation is normal.
The internet is a shared path. Each test goes through slightly different conditions.
Common factors
Other people using the home network, the time of day, the Wi-Fi signal at that moment, the server used and the route the data takes.
When to worry
Variations of 10–20% are normal. Large and frequent drops, especially on a cable, deserve investigation.
