When Wi-Fi says the password is incorrect but the password is definitely correct, the password is almost never the actual problem. In nearly every case your device is replaying a saved profile that no longer matches the router, or it is failing the security handshake for a reason the error message does not explain. The most common causes are a cached old password after a router reset or ISP swap, a WPA2 and WPA3 security mismatch, a hidden character or trailing space in the key, band steering pushing the device between the 2.4 GHz and 5 GHz radios, MAC address filtering silently rejecting the device, or a router that has simply run out of client slots.
The fastest fix is to make the device forget the network and rejoin from scratch rather than retyping the password into the same failing profile. If the whole house or office is affected instead of one device, the problem sits at the router and you should change the key there. Both routes are covered step by step below.
Quick answer
Your Wi-Fi keeps rejecting a password you know is right. Here is why that happens, and how to fix it on the device or change it on the router. When Wi-Fi says the password is incorrect but the password is definitely correct, the password is almost never the actual problem.
Why Wi-Fi says the password is wrong when it isn't
The "incorrect password" message is a catch-all. Devices show it for almost any failed authentication, including several that have nothing to do with the password itself. Work down this table before you change anything on the router.
| Cause | What you'll notice | Fix |
|---|---|---|
| Cached old password | Started after a router reset, reboot or ISP engineer visit | Forget the network on the device and rejoin |
| WPA2 and WPA3 mismatch | New phone or laptop fails, older devices connect fine | Set the router to WPA2/WPA3 mixed mode |
| Hidden character in the key | Fails on every device, including new ones | Retype the key with no spaces, no smart quotes |
| Band steering | Connects, drops, then reports a wrong password | Split the 2.4 GHz and 5 GHz names temporarily |
| MAC address filtering | One specific device fails, everything else works | Add the device MAC to the router allow list |
| Router client limit reached | Newest device to join is the one that fails | Reboot the router or remove idle devices |
| Two networks with the same name | Fails in one room, works in another | Rename the weaker access point or extender |
If more than one device stopped working at the same moment, skip the device fixes and go straight to the router section. A single failing device is almost always a saved-profile problem.
Fix it on iPhone and iPad
iOS keeps the old key in the saved network profile, so retyping the password on the same profile changes nothing. You have to remove the profile first.
- 1Open Settings, then Wi-Fi.
- 2Tap the small blue info icon next to the network name.
- 3Tap Forget This Network, then confirm.
- 4Turn Wi-Fi off, wait about ten seconds, then turn it back on.
- 5Select the network and type the password again.
Still refused? Go to Settings, General, Transfer or Reset iPhone, Reset, then Reset Network Settings. That clears every saved Wi-Fi profile and fixes the stubborn cases. You will need to re-enter passwords for your other networks afterwards, so have them to hand.
Fix it on a Mac
macOS stores Wi-Fi keys in the keychain as well as in the network profile, which is why a Mac can keep failing after you have already forgotten the network once.
- 1Open System Settings, then Wi-Fi.
- 2Click Details next to the network, then click Forget This Network.
- 3Open Keychain Access (or Passwords in System Settings on newer macOS), search the network name, and delete the saved AirPort network password entry.
- 4Restart the Mac, then rejoin the network.
On older macOS the same setting lives under System Preferences, Network, Wi-Fi, Advanced, where you select the network and click the minus button to remove it.
Fix it on Windows 11 and Windows 10
- 1Open Settings, then Network and Internet, then Wi-Fi.
- 2Click Manage known networks.
- 3Select the network and click Forget.
- 4Reconnect and enter the password.
If Windows still refuses, open Device Manager, expand Network adapters, right-click the wireless adapter and choose Uninstall device. Restart and Windows reinstalls the driver clean. A stale wireless driver produces exactly the same misleading password error.
Fix it on Android
Menu names vary by manufacturer, but the path is broadly the same on Samsung, Xiaomi, Google Pixel, Huawei and Oppo.
- 1Open Settings, then Connections or Network and Internet, then Wi-Fi.
- 2Long-press the network name, or tap the gear icon next to it.
- 3Choose Forget network.
- 4Rejoin and enter the password.
On Android, also check that Randomised MAC is not fighting a router allow list. Under the network's settings, switch Privacy from Use randomised MAC to Use device MAC, then rejoin. This single setting causes a lot of otherwise unexplainable password failures on office and hotel networks.
Change the Wi-Fi password on an Etisalat (e&) router
If you want to change the key rather than repair one device, the easiest route on an Etisalat eLife line is the e& UAE app, which avoids the admin panel entirely.
- 1Open the e& UAE app and sign in with the account holder's number.
- 2Go to your eLife or home internet service, then the Wi-Fi or Manage Wi-Fi section.
- 3Change the network name or password, then save. The router applies it within a minute or so.
To use the admin panel instead: connect to the router by Wi-Fi or Ethernet cable, open a browser and try 192.168.1.1 first, then 192.168.100.1. Log in with the admin username and password printed on the sticker on the underside of the router, not your Wi-Fi password. Open the WLAN or Wireless section, find the WPA key or Pre-Shared Key field, enter the new password, and save. Every device in the property will disconnect and needs the new key.
Change the Wi-Fi password on a du router
du Home lines follow the same pattern. The du app is the quickest path, with the admin panel as the fallback.
- 1Open the du app, sign in, and select your home internet service.
- 2Open the Wi-Fi settings section and edit the network name or password.
- 3Save, then rejoin every device using the new key.
For the admin panel, connect to the router and open 192.168.1.1 in a browser. Some du units use 192.168.0.1 instead, so try that if the first address does not load. Sign in with the admin credentials on the router sticker, open the WLAN or Wireless Security page, set a new WPA2 or WPA3 password, and save. If you have both a 2.4 GHz and a 5 GHz network listed, change the password on both so devices do not fall back to the old key on one band.
Choosing a password that won't cause this again
- Use 12 to 20 characters. Long beats complicated for Wi-Fi keys.
- Stick to plain letters and numbers. Avoid quotes, backslashes and currency symbols, which some smart TVs and printers cannot accept.
- Never start or end with a space. A trailing space is invisible and is one of the most common causes of this exact error.
- Avoid characters that look alike, such as capital I, lowercase l and the digit 1.
- Set the router to WPA2/WPA3 mixed mode rather than WPA3 only, so older devices can still authenticate.
- Write the new key on the router sticker so the next person is not locked out.
When it isn't the password at all
If you have forgotten the network on every device, changed the key on the router, and it still fails, the fault is usually hardware or line side.
- The router's wireless radio has partially failed, so it accepts wired connections but rejects wireless authentication.
- The ONT or modem was replaced during a service visit and the network name was recreated with a different key.
- An old extender, mesh node or repeater in the property is still broadcasting the same network name with the old password.
- The router's firmware is out of date, which causes handshake failures with newer phones and laptops.
- The line has an active fault and the router never fully authenticates to the ISP.

Fixing a rejected Wi-Fi password at home vs an on-site visit
Most single-device cases are a five-minute fix. The router-side cases are where a visit earns its place.
| Do it yourself | Azizi Technologies on site | |
|---|---|---|
| One device rejected, others fine | Forget the network and rejoin. Usually solved. | Not needed. |
| Every device rejected after a router reset | Log in to the router and set a new key. | We reset, re-key and reconnect every device, including printers and cameras. |
| Router admin password unknown | Factory reset, then reconfigure from the label. | We recover or reset without losing the ISP settings. |
| Old devices fail after a new router | Switch security from WPA3-only to WPA2/WPA3 mixed. | We set band, security and channel so old and new devices coexist. |
| Villa or office with many access points | Each point must carry the same key and security. | Mesh or controller-managed WiFi, keyed once, tested in every room. |
| Time | Five minutes to an evening. | Same-day visit across Dubai. |

Frequently asked questions
Why does my phone say incorrect password after I changed the Wi-Fi password?
The phone is still holding the old key in its saved profile and offers it automatically. Open the Wi-Fi settings, tap the network, choose Forget, then rejoin and type the new key. Do this on every device that connected before the change, including smart TVs, printers and cameras.
Can a router be set to reject a correct password?
Yes, in two ways. MAC address filtering only admits devices on an allow list, and a WPA3-only security mode refuses devices that can only use WPA2. Both produce the incorrect-password message. Check the Wireless and Security pages of the router and switch to mixed WPA2/WPA3 if older devices need to join.
Why does my Wi-Fi say incorrect password when the password is correct?
Because the error is a generic authentication failure, not a literal password check. Your device is usually replaying a saved profile with an old key, or failing on a WPA2 and WPA3 mismatch, MAC filtering or band steering. Forgetting the network and rejoining fixes most cases.
How do I change my Wi-Fi password in Dubai?
On an Etisalat line, use the e& UAE app under your eLife service, or open 192.168.1.1 in a browser and sign in with the admin details on the router sticker. On du, use the du app or the same router address. Look for the WLAN or Wireless Security page and update the WPA key.
What is the default admin password for an Etisalat or du router?
It is printed on the sticker on the underside or back of the router, alongside the default network name. It is not the same as your Wi-Fi password. If someone has changed it and it is lost, a factory reset with the pinhole button restores the sticker credentials and wipes any custom settings.
Why does only one device say the password is wrong?
A single failing device points to that device's saved profile rather than the router. Forget the network on that device and rejoin. If it still fails, check MAC address filtering on the router and, on Android, switch the network from randomised MAC to device MAC.
Do I need to change the password on both 2.4 GHz and 5 GHz?
Yes, if your router lists them as separate networks. Changing only one leaves devices able to join the other band with the old key, which produces inconsistent failures that look random but actually follow whichever radio each device picked. Change both, then rejoin every device once.
Can Azizi Technologies fix this on site?
Yes. We handle Wi-Fi authentication faults, router reconfiguration, dead zones and full installations across Dubai. Send us the router model and what you have already tried on WhatsApp and we will tell you whether it is a five-minute settings fix or needs a technician.
