Fix “Android Wi-Fi keeps asking for password” — authentication error, saved network loop, disconnects

Technician avatar Technician
Hi! We’ll get this Android Wi-Fi keeps asking for password problem to stop so your phone finally stays connected. I just need a clear picture of your Android phone and Wi-Fi setup so we can target the right fix instead of guessing.

Which Android phone are you using (Samsung Galaxy, Google Pixel, Xiaomi, Motorola, etc.), and roughly which Android version (Android 10, 11, 12, 13+)? When you connect to Wi-Fi, do you see a specific message like “Authentication error occurred”, “Incorrect password”, “Authentication problem” or does it just jump back to the password screen over and over?

Also, is this happening on one Wi-Fi network (your home router) or every Wi-Fi network (work, public hotspots, phone hotspot)? And have you recently changed the Wi-Fi password, router, or security type (WPA2/WPA3) on this network?
Customer
It’s a Samsung Galaxy running Android 13. At home, my Android Wi-Fi keeps asking for the password even though it’s saved. I type the correct password, it says “Authentication error occurred” or “Authentication problem” for a second, then either disconnects or just shows “Saved, secured” with no internet. Every other device (laptop, smart TV, another Android phone) connects fine, so I’m sure the Wi-Fi password is correct.

Got it, thanks — that’s classic Android Wi-Fi authentication error behavior where the phone and router can’t agree on the security details, even when the Wi-Fi password is right.

Typical reasons your Android Wi-Fi keeps asking for password are:

• A corrupted or outdated saved Wi-Fi network profile on Android, so the phone is trying to connect with old security settings.
• A mismatch between the router’s security type (WPA2/WPA3-Personal, TKIP/AES) and what the phone expects, leading to repeated authentication problems.
• Router features like MAC address filtering, access control, parental controls or a device limit blocking that phone even though the password is accepted.
• The phone using a randomized MAC address or flipping between 2.4 GHz and 5 GHz while the router only trusts the original MAC or band.

We’ll first clean up your saved Wi-Fi network on Android, then check router security (WPA2 vs WPA3, password, MAC filtering) so the phone can authenticate cleanly without looping on the password screen every few minutes.
Customer
The router is from my ISP, a dual-band Wi-Fi 5 router. Both 2.4 GHz and 5 GHz use the same SSID and password. I’ve tried restarting both the router and the phone, but the Android Wi-Fi authentication error keeps coming back. My wife’s Android connects fine, so it seems like it’s just my phone stuck in this enter password, disconnect, repeat loop.
Technician avatar Technician
Perfect, that tells us the router works in general and the problem is likely that specific saved Wi-Fi network on Android or how your phone talks to that router.

Step A — Clean up the saved Wi-Fi network on Android
1) On your Samsung, go to Settings > Connections > Wi-Fi, tap your home network, then tap Forget. If you see both 2.4 GHz and 5 GHz versions with the same name, forget them all so we remove any corrupted profiles causing the Wi-Fi keeps asking for password loop.
2) Toggle Airplane mode on for 10–15 seconds, then off to fully reset wireless radios.
3) Restart the phone once so Android clears cached Wi-Fi state.
4) On the router, if it’s easy, power it off for 30 seconds and plug it back in so it clears its device table.
5) After everything is back up, on your phone search for the Wi-Fi again and manually type the password (watch out for 0/O and l/1). Leave the “Advanced” options at default so it uses DHCP / automatic IP.

If the phone still shows “Authentication error occurred” or keeps asking for the password, we’ll adjust router security (WPA2/WPA3) and Android’s MAC address settings so they match properly.
Customer
I forgot the network on the phone, turned on airplane mode briefly, rebooted both the phone and router, and then re-joined the Wi-Fi with the password. It connected once and worked for about 10 minutes, but after a while my Android Wi-Fi disconnected and went back to “Saved, secured” with no internet. When I tapped it again, it asked for the password once more. So the Wi-Fi keeps asking for password on Android, just a bit less often now.
Technician avatar Technician
Good — that confirms the password itself is correct, but something about authentication or security negotiation is making your Android fall off and re-prompt.

Step B — Fix router security for Android Wi-Fi authentication
• Log in to the router’s web interface or app and open the Wireless / Wi-Fi settings page for your home network.
• Set the Security type to WPA2-PSK (AES) or WPA2/WPA3-Personal if all devices support it. Avoid “WEP” or “WPA/WPA2 mixed with TKIP” — they’re insecure and often cause Android Wi-Fi authentication problems.
• Make sure the same Wi-Fi password is used for both 2.4 GHz and 5 GHz if they share an SSID, or create separate SSIDs (like “Home-2G” and “Home-5G”) so we can test each band.
• Temporarily turn off MAC address filtering, access control lists, parental controls or device-limit features that might block your Samsung’s MAC address.
• Save the changes and reboot the router so the new security settings fully apply.

After that, reconnect on your Android. If it still shows an authentication error, we’ll adjust the phone’s MAC randomization and reset broader network settings so Wi-Fi doesn’t keep forgetting or rejecting the password.
Customer
I checked the router and it was set to WPA2/WPA3 mixed. I switched it to just WPA2-PSK (AES), turned off MAC filtering and access control, then rebooted it. My Samsung connected again and worked for a while, but if I move further from the router I sometimes see “Authentication error” and the Wi-Fi on Android keeps asking for the password again. Other devices stay connected with no problem.
Technician avatar Technician
Nice work on the router side — now we’ll give Android a full network settings reset and make sure it presents itself consistently to the router.

Step C — Android fixes for Wi-Fi authentication error
1) On your Samsung, go to Settings > General management > Reset > Reset network settings. This clears all Wi-Fi, mobile data and Bluetooth profiles (you’ll need to reconnect to Wi-Fi networks afterwards).
2) After the reset and reboot, go to Settings > Connections > Wi-Fi, tap your home network, then open Advanced (or similar). Set MAC address type to Phone MAC instead of “Randomized MAC” for this network, so the router always sees the same device address.
3) Confirm IP settings are on DHCP / Automatic. Don’t use a static IP unless your ISP or admin told you to.
4) If you’re using a VPN, firewall app or “Wi-Fi optimizer / cleaner”, disable it temporarily — some apps interfere with Wi-Fi handshakes and cause Android Wi-Fi keeps asking for password symptoms.
5) Optionally, boot into Safe mode (long-press Power > tap and hold “Power off” > “Safe mode”) and test Wi-Fi; if it works fine there, a third-party app is likely causing the authentication problem.

After doing steps 1–3, reconnect to your Wi-Fi with the password again and see if your Android phone stays connected to Wi-Fi when you move around the house.
Customer
I did the network reset and set the MAC type to “Phone MAC” for my home network. IP is on DHCP and I turned off my VPN app. Now the phone connects right away and doesn’t instantly drop. I walked around the apartment and it mostly stayed connected — once it briefly dropped to mobile data and reconnected on its own without asking for the password. Is that normal, or should I update the router firmware too?
Technician avatar Technician
A brief handoff without asking for the password is normal — the key is that the Android Wi-Fi isn’t prompting you for the password every time now. To smooth things out a bit more, we can tune the router and Wi-Fi signal.

Step D — Update router firmware and stabilize Wi-Fi signal
• In the router app or web page, check for a firmware update. Many ISPs push fixes for Wi-Fi authentication problems on Android and general stability in newer firmware versions.
• If 2.4 GHz and 5 GHz share the same name, consider giving them separate SSIDs (for example, “Home-2G” and “Home-5G”). Connect the phone to the band that works best (2.4 GHz reaches further, 5 GHz is faster but shorter range). This can reduce flapping between bands that looks like random disconnects.
• Manually set a less crowded channel on 2.4 GHz (1, 6 or 11) and a stable channel on 5 GHz instead of “Auto” if your area is congested. This helps avoid re-negotiations that can trigger auth errors on Android.
• Don’t hide your SSID or use very exotic characters in the Wi-Fi name/password that some devices struggle with; a strong phrase with letters, numbers and a few symbols is ideal.

After these adjustments, you should see fewer random drops and no more situations where your Android Wi-Fi keeps asking for the password again.
Customer
I updated the router firmware and split the bands so I now have “Home-2G” and “Home-5G”. I put my Samsung on the 2.4 GHz one since I use it further from the router. Since then, I haven’t seen the Wi-Fi authentication error at all and it hasn’t asked for the password again. It feels much more stable now. Anything else I should do so this Android Wi-Fi keeps asking for password issue doesn’t come back later?
Technician avatar Technician
Great — that’s exactly what we wanted. Now we’ll “lock in” the fix so your Android phone doesn’t fall back into an endless Wi-Fi password loop later.

Step E — Keep Android Wi-Fi stable long-term
• Avoid changing your Wi-Fi password or security type too often; each change forces every device to renegotiate and Android can pile up broken profiles.
• When you do change the Wi-Fi password, always Forget the network on Android and re-add it once, instead of repeatedly typing a new password over an old profile if you see authentication errors.
• Keep both your Android OS and router firmware updated. Updates often include fixes for Wi-Fi disconnecting on Android and compatibility with newer WPA2/WPA3 features.
• Avoid aggressive third-party “Wi-Fi optimizer” or “battery saver” apps that constantly toggle Wi-Fi; they can cause random disconnects and Android Wi-Fi keeps asking for password symptoms.
• Take a quick screenshot or note of your working Wi-Fi and security settings so if the router is reset, you can recreate the setup that you know your Android likes.

With these habits, your Android Wi-Fi connection should stay stable, and if it ever starts asking for the password again, you’ll know exactly which settings to check first.
Customer
Got it. I’ll leave security on WPA2-PSK, keep the phone on the same 2.4 GHz network, and avoid “optimizer” apps. So far, the Android Wi-Fi authentication problem seems completely gone — no pop-ups and no more “Incorrect password” messages when I know it’s right. Thanks for walking me through it step by step.
Technician avatar Technician
You’re very welcome — glad we could stop the Android Wi-Fi keeps asking for password loop and get your phone back on stable Wi-Fi.

Summary: To fix an Android Wi-Fi authentication error, forget the saved network, reset network settings on Android, set the router to WPA2-PSK (AES), temporarily disable MAC filtering, update router firmware, and use a consistent Phone MAC on your device. Once the phone and router agree on security, Wi-Fi stops disconnecting and won’t keep prompting for the password.

If you ever get stuck again — Android Wi-Fi keeps disconnecting, you see “Authentication problem”, or the password loop comes back — you can open a chat with an expert and we’ll trace the issue live with you.

If a friend or coworker says their Android Wi-Fi keeps asking for the password, shows an authentication problem, or their Android phone won’t stay connected to Wi-Fi, you can share this checklist — and if you’d like someone to click through Android and router settings with you in real time, just start a chat with an expert and we’ll take it from there.

Quick answer: the accepted fix

Accepted fix when Android Wi-Fi keeps asking for password: forget the Wi-Fi network, run a Reset network settings on Android, set the router to WPA2-PSK (AES) with MAC filtering disabled, update router firmware, and reconnect using Phone MAC. This stops the Wi-Fi authentication error loop so your Android phone stays connected without constant password prompts.

Why Android Wi-Fi keeps asking for password (authentication error, security mismatch, saved network issues)

Most Android Wi-Fi keeps asking for password problems are not about typing the wrong password — they’re about how your Android phone and router negotiate security. When the saved profile on the phone doesn’t match the router’s current WPA2/WPA3 settings, or the router blocks the phone’s MAC address, you see “Authentication error occurred”, “Authentication problem” or “Incorrect password” even though the password is correct.

Other triggers include randomized MAC addresses, aggressive battery saver, VPN or Wi-Fi “cleaner” apps, and routers using outdated modes like WEP or WPA/TKIP. Cleaning up the saved Wi-Fi network on Android, standardizing on WPA2-PSK (AES), and turning off strict MAC filtering usually stops the Android Wi-Fi authentication problem so the device connects cleanly and stays online.

How to tell if “Wi-Fi authentication error” is your Android phone, router, or password

To narrow down an Android Wi-Fi authentication error, start simple:

First, try connecting your Android phone to a different Wi-Fi network (work, public hotspot, your own phone’s hotspot). If Wi-Fi works there without password loops, your phone is fine and the issue is likely with the home router settings. If your Android shows the same Wi-Fi keeps asking for password behavior everywhere, the problem is on the phone side and a network reset or OS/app cleanup is needed.

Next, confirm other devices can connect to your home Wi-Fi using the same password. If every device fails, the password or Wi-Fi security type is wrong and needs to be fixed in the router interface. When only one Android phone has trouble, focus on forgetting the network, resetting network settings, disabling VPN/optimizer apps, and making sure the router uses a simple, compatible security mode like WPA2-PSK (AES).

Android Wi-Fi keeps asking for password — quick troubleshooting tips

Reset the saved network, match WPA2/WPA3 settings, and stop the authentication loop.

Fast path: on the phone, Forget the Wi-Fi network → run Reset network settings in Android → reconnect using the correct password → on the router, use WPA2-PSK (AES) with MAC filtering and access control turned off → set MAC address type to Phone MAC on Android → update router firmware and avoid “Wi-Fi optimizer” apps that toggle the connection.

FAQ

Why does my Android Wi-Fi keep asking for the password?

When Android Wi-Fi keeps asking for password, it usually means the saved network profile on your phone doesn’t match the router’s current security settings or password. A corrupted profile, security mode mismatch (WEP/WPA/WPA2/WPA3), MAC filtering, or randomized MAC address can cause repeated Wi-Fi authentication errors even with the correct password.

How do I fix “Authentication error occurred” on Android Wi-Fi?

To fix an Android Wi-Fi authentication error, first Forget the network on your phone and reconnect. If that doesn’t help, run Reset network settings in Android, then set your router to WPA2-PSK (AES), disable MAC filtering, and reconnect using the correct password with MAC address type set to Phone MAC. Also temporarily disable VPN or “Wi-Fi optimizer” apps while testing.

Why does my Android show “Saved, secured” but no internet?

“Saved, secured” on Android means the Wi-Fi password is accepted, but the phone either isn’t getting a valid IP address or is blocked by router rules. Check that IP is set to DHCP, your router’s DHCP pool isn’t exhausted, and there are no access control or parental control rules blocking that device. In many cases, updating router firmware and resetting Android’s network settings resolves this.

When should I reset network settings or replace my router?

If your Android Wi-Fi keeps disconnecting, asking for the password and showing authentication problems on multiple networks, a Reset network settings on the phone is a good next step. If Android works fine on other networks but only fails at home after you’ve fixed passwords, security type, MAC filtering and firmware, your router may be outdated or unstable — in that case, replacing it with a modern Wi-Fi 5/6 router is worth considering.
