TV Wi-Fi Password Error: How to Fix It Fast

If your TV keeps rejecting your Wi-Fi password or drops the connection after a wrong entry, this guide walks you through the exact steps to get it back online. You’ll clear the saved network, re-enter the password correctly, and fix the most common causes of the error—usually a typo, a saved wrong password, or a router setting.

What You’ll Need

Your TV remote
The exact Wi-Fi network name (SSID) and password (check your router’s label or your internet provider’s app)
Access to your router’s settings (usually via a web browser or app) if the issue persists

Step-by-Step

Go to your TV’s network settings. The path varies by brand, but it’s usually under Settings → Network or General → Network. On some TVs, it’s under System → Network.
Select “Wi-Fi” or “Wireless” as the connection type. If your TV offers both wired and wireless, choose wireless.
Find your network name (SSID) in the list of available networks. If your network doesn’t appear, skip to Troubleshooting below.
Select “Forget” or “Delete” this network. This clears the saved password that may be wrong. If you don’t see a forget option, look for “Disconnect” or “Remove” after selecting the network.
Re-select your network from the list and choose “Connect” or “Join.”
Type the password carefully. Use the on-screen keyboard. Pay attention to:
- Capital letters (the password is case-sensitive)
- Numbers vs. letters (e.g., 0 vs. O, 1 vs. l)
- Special characters like ! @ # $ % ^ & *
Check the “Show password” box if your TV has one. This lets you see what you’ve typed and catch typos.
Press Connect or OK. Wait 10-30 seconds for the TV to authenticate.
Confirm the connection. Once connected, the TV will usually show a checkmark or “Connected” next to the network name. Run a network test if available (often under the same menu) to confirm internet access.

Common Mistakes

Typing the wrong password. The most common error is a simple typo, especially with long passwords containing mixed characters.
Using the wrong network. Your router may broadcast multiple networks (e.g., a 2.4GHz and a 5GHz band, or a guest network). Make sure you’re connecting to the one with the password you have.
Including spaces. Some passwords contain spaces, but the TV’s keyboard may not show them clearly. Double-check if your password has any.
Not clearing the old password. If you recently changed your router password, the TV may still be trying the old one. Forgetting the network forces it to ask for the new one.
Caps Lock on. If your TV’s virtual keyboard has a caps lock toggle, it may be on without you noticing.

Tips

Use your phone as a reference. Open your phone’s Wi-Fi settings, view the saved password (on Android you can usually see it under the network info; on iPhone you may need to go to Settings → Wi-Fi → the “i” icon and tap Password), and type it exactly on the TV.
Simplify temporarily. If you’re stuck, temporarily change your router’s password to something short and simple (like “test1234”), connect the TV, then change it back to your normal password and update the TV again. This isolates the issue.
Reboot the TV. A quick power cycle (unplug for 30 seconds) can clear temporary network glitches.
Check for TV software updates. Outdated TV firmware can cause Wi-Fi bugs. Look for “Software Update” in the TV’s settings and install any available updates.

Troubleshooting

If the TV still says “incorrect password”:

Verify the password on another device (phone or laptop) by connecting to the same network. If that device also fails, the password is wrong—reset it on your router.
Restart your router and modem. Unplug them for 30 seconds, plug them back in, wait for the lights to stabilize, then try again.

If the network doesn’t show up at all:

Move the TV closer to the router temporarily. Walls and distance can hide the signal.
Check if your router is broadcasting the SSID. If “Hide SSID” is enabled, you’ll need to manually add the network on the TV (look for “Add Network” and enter the SSID and security type).
Restart the TV and router.

If the TV connects but has no internet:

Run the TV’s network test (usually in the same settings menu). It will tell you if the problem is DNS, IP, or internet.
On your router, check if MAC address filtering is on. If so, add the TV’s MAC address (found in the TV’s network status screen) to the allowed list.
Try changing the TV’s DNS to a public one like 8.8.8.8 (manual DNS settings are usually under network settings).

If the TV keeps forgetting the password after a restart:

This is often a TV firmware bug. Check for updates.
Some TVs have a “power saving” mode that disconnects Wi-Fi when off. Disable that in the eco/power settings.

Frequently Asked Questions

Q: Why does my TV say the Wi-Fi password is wrong when I know it’s correct?
A: The most common cause is a hidden character or a case mismatch. Try using the “show password” option, or re-type the password from scratch. Also, make sure you’re entering it for the correct network (e.g., not the guest network).

Q: Can I use WPS instead of typing the password?
A: Yes, if your router has a WPS button. On the TV, choose the WPS option in the network settings, then press the WPS button on your router within 2 minutes. This bypasses typing entirely.

Q: My TV is too old to support modern Wi-Fi security (WPA3). What do I do?
A: Log into your router and change the security mode to WPA2/WPA3 mixed, or WPA2 only. Older TVs often don’t support WPA3. This is a router setting, not a TV setting.

Q: How do I find my Wi-Fi password if I forgot it?
A: Check the sticker on your router (often labeled “Network Key” or “WPA2 Password”). If it’s been changed, log into the router’s admin page (usually via a browser at an address like 192.168.1.1) and look under Wireless Settings. If you can’t access that, reset the router to factory defaults and use the default password from the sticker.

Q: Why does my TV keep disconnecting after connecting successfully?
A: This is usually a signal strength issue or a router setting like “band steering” that switches between 2.4GHz and 5GHz. Try connecting to the 2.4GHz band specifically (rename the bands separately in your router settings), or move the TV closer to the router.

Q: Does restarting the TV help with Wi-Fi issues?
A: Yes, a full power cycle (unplug for 30 seconds) clears the TV’s network cache and often resolves temporary connection errors. It’s the first thing to try before more complex fixes.
