What might cause this?
Possible reasons depend on the exact model. These are checks, not a confirmed diagnosis.
Possible causes
- Router and extender IP address assignment may conflict.
- The main router may be offline or the device on the wrong network.
What can you try?
Try these safe, user-level checks in order; do not open the device. Menu labels may differ by version.
- 01
Step 1
Connect directly to the main router and confirm it has internet.
- 02
Step 2
Restart the extender near the main router.
- 03
Step 3
Check IP and DHCP settings using your model-specific TP-Link guide.
How can you confirm the fix?
Websites open when connected to the extender.
When should you contact service?
If the issue persists after these safe checks, contact TP-Link official support with your exact model and what you tested.
⚠ Stop using a device if it overheats, shows liquid damage, smells burnt or has a swollen battery.
Will a repair cost money?
Settings, cables and user checks may require no repair. Hardware costs depend on the exact model, warranty and service diagnosis; no fixed price is promised.
Quick answers
Could these checks affect warranty?
Use only external checks recommended for end users by the manufacturer. Opening batteries, electronics or sealed parts can create safety and warranty risks.
What if the steps do not help?
Write down your model, software version and test results. Share those details with official support rather than repeating potentially unsafe actions.
