Wi-Fi: Password Changed, Need to Reconnect — What It Means & How to Fix It

What Does This Error Mean?

When your Wi-Fi password changes — whether you changed it, someone else in the household did, or the router was reset — every device needs to be updated with the new password. Devices using the old password will fail to connect. This is not a malfunction — it is normal security behavior.

Affected Models

Windows 10
Windows 11
Android
iOS
macOS
Smart TVs
Smart home devices

Common Causes

Someone changed the Wi-Fi password in the router's admin settings
The router was factory reset, which reverted the password to the default printed on the device
The ISP remotely updated the router firmware and reset settings including the password
A household member changed the password without telling others
A security breach prompted a password change to secure the network

How to Fix It

Find the current Wi-Fi password. Log into the router admin page (usually 192.168.1.1 or 192.168.0.1) and look in the Wireless settings section. The current password is shown there.

If you just reset the router, the password is printed on the label on the back or bottom of the router.
On Windows: forget the network and reconnect. Go to Settings > Network & Internet > Wi-Fi > Manage known networks. Click your network, choose Forget, then reconnect and type the new password.

Windows will not update a saved password automatically — you must forget and re-add the network.
On iPhone/iPad: forget and rejoin. Go to Settings > Wi-Fi > tap the (i) next to the network > Forget This Network. Then tap the network name and enter the new password.

All iOS devices need to be updated individually — there is no shared password list.
On Android: long-press the network name in Wi-Fi settings and choose Forget. Then tap the network and enter the new password.

On Samsung devices, tap the network name then tap Forget to clear the old credentials.
For smart home devices (TVs, speakers, cameras): open the manufacturer's app and look for a Wi-Fi or network setup option. Most devices have a way to update Wi-Fi settings without a full factory reset.

Devices like Google Home, Amazon Echo, and smart TVs all have in-app Wi-Fi reconfiguration.

When to Call a Professional

Updating a Wi-Fi password on your devices is something anyone can do — no technician needed. If you forgot the new password and cannot access the router, your ISP can help you log in or guide you through a reset. For smart home devices that are hard to reconnect, check the manufacturer's app or manual for a Wi-Fi reset procedure.

Frequently Asked Questions

Do I have to update every device in my house manually?

Yes, unfortunately. There is no way to push a new Wi-Fi password to all devices at once. Every phone, laptop, tablet, TV, and smart home device needs to be updated individually. For large households, keep a list of every device so nothing gets missed.

Is changing my Wi-Fi password regularly a good security practice?

Changing it occasionally is worthwhile — especially if you have given it out to guests. However, very frequent changes create inconvenience without much extra security benefit. A strong, unique password changed once or twice a year, and using WPA3 if available, is a practical approach for most households.

My smart TV won't let me enter a new Wi-Fi password. What do I do?

Most smart TVs have a Network or Wi-Fi settings menu in their Settings app. Navigate there and look for a 'Forget network' or 'Change Wi-Fi' option. If the TV is not showing any option, a factory reset of the TV may be necessary as a last resort. Check the TV manufacturer's support page for model-specific instructions.
