Troubleshoot a Wi-Fi connection step by step
Separate router, line, room and device problems before changing equipment or service plans.

The answer in 30 seconds
A weak Wi-Fi signal and a slow internet line feel similar while browsing. Changing a plan or buying a repeater before locating the fault may leave the real problem untouched.
Check which devices and rooms are affected, test near the router, compare with Ethernet if available, then change one factor and repeat the same test.
Examples to adapt
Check its Wi-Fi connection and updates before changing the router.
Look at router placement and walls before considering an access point.
Inspect the router's connection status and the provider's service information.
Follow the method
- 1Map the symptom
Record device, room, time, error and whether the connection drops or only slows.
- 2Compare locations
Test near the router and in the problem area with the same device.
- 3Separate line from Wi-Fi
Use Ethernet or another known-good device when possible.
- 4Change one factor
Move the router, reconnect the device or contact the provider based on the evidence, then retest.
A checklist to keep
Use these checks to record what you found. The grid supports a decision; it does not make one for you.
| Check | What to examine | Action |
|---|---|---|
| Scope | One device or all? | Identify |
| Location | One room or everywhere? | Compare |
| Line | What does Ethernet show? | Test |
| Change | Which single factor was changed? | Record |
| Result | Did the symptom improve? | Repeat |

What to check
A repeater in a weak-signal area can repeat a weak connection.
A device problem may not affect other devices.
Router placement and neighbouring networks can change Wi-Fi performance.
Common questions
Should I reset the router immediately?
First record the symptom and check other devices; a restart can help but erase useful clues.
When should I contact the provider?
When a wired or near-router test remains poor, the line is down or the router reports an access fault.
