Router Or ISP Problem?
Slow internet can come from the provider, plan, modem, router, Wi-Fi coverage, or the device you are using. The trick is testing in the right order.
Signs It May Be The ISP Or Plan
- Speed is poor even beside the modem or router.
- Upload speed is too low for video calls or cloud backups.
- Everyone in the home is slow at the same time.
- Performance gets worse at busy evening hours.
Signs It May Be The Router Or Wi-Fi
- Speed is good beside the router but poor in certain rooms.
- Devices disconnect or lag on Wi-Fi but not near the router.
- The router is old, hidden, or placed at one end of the home.
Decision rule
If every location is slow, check the plan/provider path. If only distant rooms are slow, check Wi-Fi coverage and router placement.
