Slow internet is not always caused by weak signal strength. In many cases, the available connection speed simply may not match the number of devices or the type of online activity happening at the same time.
Streaming video, video calls, and cloud syncing all compete for bandwidth. When several devices share the same connection, performance can drop even if the WiFi signal appears strong.
Because modern apps automatically increase quality when faster internet is available, bandwidth demand may rise without users realizing it.
This often leads to buffering videos, lag during meetings, or slow loading websites despite having an active connection.
The calculator below estimates how much internet speed your household or device usage realistically requires based on common real-world activities.
