If your Wi-Fi password stops working after a router reset, check the default password on the router label or in your internet provider’s app. If you changed the password, use the updated one. Next, forget the saved Wi-Fi network on your device and reconnect. If the password is still rejected, verify the router’s Wi-Fi settings and test another device to identify the problem.
Your Wi-Fi password stopped working after you reset your router. Your phone or laptop now says “Incorrect Password,” even though you are entering the same password you used before.
The problem may be that your router’s network settings changed, your device saved outdated credentials, or you selected the wrong Wi-Fi network. The correct fix depends on whether you restarted the router, performed a factory reset, or changed the password manually.
To fix a Wi-Fi password after a router reset, confirm the correct network name, check the current Wi-Fi password, forget the saved network on your device, and reconnect. If the password still fails, test another device and verify the router’s wireless settings before making further changes.
Why Your Wi-Fi Password Stops Working After a Reset
A router restart and a factory reset are not the same.
A restart turns the router off and back on without normally erasing its settings. A factory reset can erase custom settings and restore the manufacturer’s default configuration.
After a factory reset, your router may broadcast its original Wi-Fi name and use its default password. Your phone or laptop might still be trying to connect using the network name and password saved before the reset.
The exact behaviour depends on your router and internet provider. Some provider-managed routers use app-controlled settings or customized credentials.
For an example of how factory resets work, see Google Nest and Google Wifi factory-reset instructions.
How to Fix a Wi-Fi Password After a Router Reset
1. Check the Router’s Default Wi-Fi Name and Password
Start by checking the label on your router. It is often located underneath, on the back, or on the side of the device.
Depending on the model, the label may show:
- The default Wi-Fi network name, also called the SSID.
- The default Wi-Fi password or wireless key.
- The router model number.
- Setup information or an administration address.
Compare the network name shown on your phone or laptop with the name printed on the router.
If you performed a factory reset, the original network name and password may now be active. Try the printed credentials after confirming that you are connecting to the correct network.
However, the label may not show the current password if you or your provider changed it after installation. If your router is managed through an internet provider’s app, check the app or the provider’s setup instructions.
Security tip: Do not share a photograph of your router label without hiding the Wi-Fi password and other sensitive setup details.
2. Forget the Saved Wi-Fi Network and Reconnect
Your phone or computer may have retained the old Wi-Fi credentials. Forgetting the network removes the saved connection profile so you can reconnect using the current details.
On an iPhone or iPad
- Open Settings and select Wi-Fi.
- Find the affected network.
- Tap the information button beside the network.
- Select Forget This Network, if available, and confirm.
- Select the correct network again.
- Enter the current password carefully.
On Android
- Open Settings and select Wi-Fi or Network and Internet.
- Select the affected network.
- Tap Forget or Remove, depending on your device.
- Select the network again.
- Enter the current password.
On Windows 11
- Open Settings.
- Select Network & internet, then Wi-Fi.
- Open Manage known networks.
- Select the affected network and choose Forget.
- Return to the Wi-Fi list and reconnect using the current password.
Menu names may vary by device and operating-system version.
Before reconnecting, check that Caps Lock is off when using a computer and that you have not accidentally included a space when copying the password. Wi-Fi passwords are case-sensitive, so uppercase and lowercase letters must match.
For device-specific instructions, see Apple’s Wi-Fi password help and Microsoft’s Windows Wi-Fi troubleshooting guide.
If the correct password is still rejected, continue to the next step. Forgetting a network cannot fix a password mismatch in the router itself.
3. Confirm That You Are Connecting to the Correct Network
After a factory reset, your router may use its original network name instead of the custom name you previously chose.
Open the Wi-Fi list on your device and look for the network name printed on the router or shown in your provider’s app.
If you see several similar network names, do not assume they all belong to your router. Nearby networks, guest networks, range extenders, and mesh access points can have similar names.
If you use a mesh system or a separate access point, check that you are selecting the network currently configured for your home.
If your expected network name does not appear, allow the router to finish starting and check again. If it remains missing, consult the router manufacturer’s setup instructions to confirm that Wi-Fi is enabled and configured correctly.
Avoid selecting an unfamiliar network simply because its name resembles yours. Connecting to the wrong network will not solve the original problem and could expose your device to an untrusted connection.
4. Verify the Router’s Wi-Fi Settings
If the password on the label does not work, verify the current wireless configuration.
Use your router manufacturer’s instructions, your internet provider’s app, or the documented administration address to access the settings. Common private router addresses include 192.168.0.1 and 192.168.1.1, but the correct address depends on your network.
Once signed in, open the wireless or Wi-Fi section and check:
- The current Wi-Fi network name.
- Whether the wireless network is enabled.
- The configured Wi-Fi password, if the interface allows you to view or change it.
- The security mode and compatibility settings.
- Whether you are using the main network or a guest network.
Do not confuse the Wi-Fi password with the router administrator password. The Wi-Fi password connects your devices to the wireless network. The administrator password lets you access the router’s configuration settings. These credentials may be different.
If you cannot sign in, check the router manual or contact your provider. Avoid repeatedly guessing administrator credentials or changing settings you do not understand.
If you choose to change the Wi-Fi password, save the settings and reconnect your devices using the new credentials. Devices using the old password will generally need to reconnect.
Where possible, use a strong, unique Wi-Fi password and the security settings recommended by your router manufacturer. Do not disable wireless security to get a device connected.
5. Test Another Device to Narrow Down the Problem
Try connecting a second phone, tablet, or laptop to the same Wi-Fi network. This helps establish whether the problem affects one device or several.
| What happens | What it may indicate | What to do next |
|---|---|---|
| Every device rejects the password | The credentials or router configuration may have changed | Verify the current network name and password in the router or provider app |
| Only one device rejects the password | A saved credential or device-specific issue may be involved | Forget the network and reconnect; check for device-specific updates |
| The network name is missing | Wi-Fi may be disabled, the router may still be starting, or its configuration may have changed | Check the wireless settings and router setup instructions |
| Devices connect but have no internet | The password may not be the main problem | Check the router’s internet connection and provider service status |
These symptoms are clues rather than definitive diagnoses. For example, if one device connects successfully but another does not, concentrate on the affected device before changing the router’s settings again.
If devices connect to Wi-Fi but cannot access websites, see our guide to router lights being on but no internet. That is a different problem from a password being rejected.
6. Restart the Router or Contact Your Provider
If you have confirmed the correct network name and password, a normal restart may help resolve a temporary router problem.
Follow your manufacturer’s recommended restart procedure. For a typical router with an accessible power cable, this may involve turning it off or disconnecting its power briefly, reconnecting it, and allowing it to finish starting. Follow your provider’s instructions for equipment that requires a specific procedure.
A restart normally preserves the router’s settings, so it will not correct an incorrect password configured in the router.
If every device still rejects the verified credentials, check whether your provider manages the router remotely or requires a particular setup process. Contact the provider or router manufacturer if you cannot access the wireless settings or the network remains unavailable.
Before contacting support, note the router model, whether you performed a restart or factory reset, the network name you are trying to use, and whether one or several devices are affected. This information helps support staff narrow down the cause more quickly.
Avoid performing another factory reset just to test the password. A factory reset may erase custom network names, guest networks, parental controls, and other settings. Use it only when the manufacturer’s instructions or your provider’s support recommends it.
Why Your Correct Wi-Fi Password May Still Be Rejected
If you have followed the steps above and still cannot connect, consider these possible causes.
The router’s credentials changed. A factory reset may restore the default network name and password.
Your device has outdated saved credentials. Forgetting the network and reconnecting can help if the saved connection profile is the problem.
You selected the wrong network. Similar network names can make it easy to choose a neighbouring network, guest network, or another access point.
The wireless configuration is incompatible with the device. Certain security or compatibility settings can prevent some devices from connecting. Consult the router manufacturer’s guidance before changing security modes.
The problem is actually the internet connection. If your device connects to Wi-Fi but websites do not load, investigate the router’s internet connection rather than repeatedly entering the password.
Frequently Asked Questions
Does restarting a router change the Wi-Fi password?
Usually, no. A normal restart generally preserves the router’s settings. A factory reset can erase custom settings and restore default credentials. The exact behaviour depends on the router and provider.
Where can I find my Wi-Fi password after a factory reset?
Check the router’s label, setup card, manufacturer’s documentation, or internet provider’s app. If the password was changed after installation, the printed default may no longer be correct.
Should I reset my phone if the Wi-Fi password is not working?
Usually, no. Start by forgetting the affected network and reconnecting with the correct credentials. Resetting all network settings is more disruptive and may remove other saved network information.
Why does my phone say “Incorrect Password” when the password is correct?
Your device may be using an old saved password, connecting to the wrong network, or encountering a wireless configuration compatibility issue. Verify the network name and current credentials before making additional changes.
Will changing my Wi-Fi password disconnect my other devices?
Devices using the old password will generally need to reconnect with the new one. Update the saved credentials on phones, computers, smart TVs, printers, and other wireless equipment.
Final Thoughts
If your Wi-Fi password stops working after a router reset, first establish whether you restarted the router or performed a factory reset. Then confirm the network name, verify the current credentials, forget the saved network, and reconnect.
If several devices reject the correct password, investigate the router’s wireless settings or contact your provider before performing another factory reset.
The goal is to identify what changed and correct that specific issue—not to keep resetting equipment or changing settings at random.
