If your WiFi is slow, unstable, or not working, follow the steps below in order.
Do not skip steps. Each one helps identify the cause of the issue.
Step 1: Check If the Problem Is WiFi or Your Internet
- Connect a device using a LAN cable directly to your router
- Test your internet connection
Result:
- If the wired connection works fine, the issue is WiFi
- If the wired connection is also slow or not working, the issue is likely your connection
Step 2: Restart Your Equipment
Restart everything properly:
- Switch off your router
- Switch off your fibre ONT
- Wait 30 seconds
- Switch on the ONT and wait until all lights are stable
- Switch on your router
This clears temporary issues and often restores connectivity.
Step 3: Check Your Distance From the Router
- Move closer to your router
- Check if performance improves
If it improves:
The issue is signal strength or coverage
Step 4: Check for Interference
WiFi can be affected by:
- Thick walls
- Metal objects
- Microwaves and other electronics
- Nearby WiFi networks
Try:
- Moving your router to a more open space
- Keeping it away from other electronics
Step 5: Switch Between 2.4GHz and 5GHz
- Use 5GHz when you are close to the router for better speed
- Use 2.4GHz when you are further away for better range
If unsure, test both and compare performance.
Step 6: Check How Many Devices Are Connected
Too many active devices can slow your WiFi.
- Disconnect devices you are not using
- Pause downloads or streaming on other devices
Step 7: Test Your Speed
- Run a speed test near the router
- Compare results in different rooms
If speeds are good near the router but poor elsewhere:
You likely have a coverage issue
Step 8: Improve Your Coverage
If you have weak signal in parts of your home:
- Reposition your router
- Consider a WiFi extender for small gaps
- Use a mesh WiFi system for larger homes
Step 9: Check for Device-Specific Issues
If only one device has issues:
- Restart the device
- Forget and reconnect to the WiFi network
- Check for software updates
Quick Fix Checklist
If you need a fast solution:
- Restart your router and ONT
- Move closer to the router
- Switch between 2.4GHz and 5GHz
- Disconnect unused devices
Key Takeaway
Most WiFi issues are caused by signal strength, interference, or too many connected devices.
Following these steps in order will help you quickly identify and fix the problem.
