When Wi-Fi rejects a password you know is right, start with two things: try a second device on the same network and restart the router. If the other device can’t connect either, the problem is the router or your internet provider. If only your device fails, forget the network and rejoin, try the other frequency band, and save the heavier options for last.
First, find out whose problem it is
Grab another phone or laptop and try the same network. Both Apple and Microsoft give this advice: if other devices connect, the issue is probably with yours. If none do, suspect the router or your provider.
If nothing connects, check the lights on the router and modem too. When the provider’s service is down, the Wi-Fi network can still show up in the list while the connection never completes. Restart the equipment, then call your provider if it persists.
1. Restart the router and modem
This fixes more than any other step. Google describes it like this, and Microsoft gives a similar order for setups with a separate modem and router:
- Unplug the router and confirm its lights go off.
- Wait about 30 seconds.
- Plug it back in and wait roughly 30 seconds for the lights to return.
If your modem and router are separate boxes, Microsoft says to unplug both, plug in the modem first, let its lights settle, then plug in the router. Give it a few minutes before you try to connect.
2. Restart your device and check Airplane mode
Google suggests restarting your phone before anything else. Make sure Airplane mode is off, too. Switching it on for a few seconds and off again can make the device search for networks from scratch.
On iPhone, Apple notes that Wi-Fi has to be on and that a blue checkmark next to the network name means you’re connected. If the Wi-Fi setting is grayed out, restart the device.
3. Forget the network and rejoin
Forgetting the network wipes what the device saved about it and lets you start clean, which helps when the saved entry has gone stale.
Windows 11: go to Settings > Network & internet > Wi-Fi > Manage known networks, select the network and choose Forget. Then reconnect and type the password again.
Android and iPhone: open the Wi-Fi settings, tap the network name and choose the option to forget it (the exact wording depends on the maker and software version). Then pick the network again and type the password carefully, watching upper and lower case.
If you can’t remember the exact password, see how to see your Wi-Fi password on iPhone, Android and Windows 11.
4. Switch between 2.4 GHz and 5 GHz
Many routers broadcast two networks: 2.4 GHz, which reaches farther, and 5 GHz, which is faster up close. Microsoft and Apple both suggest trying the other band when one doesn’t work. If both networks share one name, check the router’s manual to see how to separate them.
Stand close to the router while you test. Google points out that with no signal bars filled, you may simply be out of range.
5. Turn Wi-Fi off and use mobile data for a moment
Google suggests switching Wi-Fi off and mobile data on to see if anything changes, then going back to Wi-Fi. It sounds minor, but it forces the phone to redo the connection.
On iPhone, Apple also recommends turning off Wi-Fi Assist (listed under Cellular) and checking whether a VPN or security app is getting in the way. If removing the app and restarting fixes it, contact the app’s maker.
6. On Windows 11, run the troubleshooter and network commands
Windows has a built-in diagnostic: Settings > Network & internet > Status > Network troubleshooter. If that doesn’t fix it, open Command Prompt as administrator and run these in order:
netsh winsock reset
netsh int ip reset
ipconfig /release
ipconfig /renew
ipconfig /flushdnsThese reset parts of the network stack and ask the router for a fresh address. Restart the PC afterward. If your Wi-Fi adapter is missing altogether, our guide to Wi-Fi not showing up on Windows 11 covers that case.
7. Install updates
Apple says to update to the latest iOS or iPadOS under Settings > General > Software Update. On Windows, use Settings > Windows Update > Check for updates. Updates can fix driver and connection bugs.
8. Check the router
Apple notes that the router’s firmware should be current and compatible with your device, and that some networks use security features that block unauthorized devices. If the network belongs to an office, school or apartment building, a rule set by its administrator could be the cause, and that person is the one who can change it.
9. Reset network settings (last resort)
This erases saved networks and passwords, so use it only after the steps above.
- iPhone: Settings > General > Transfer or Reset [device] > Reset > Reset Network Settings. Apple warns that it removes saved Wi-Fi networks and passwords, cellular settings, and VPN and APN settings.
- Windows 11: Settings > Network & internet > Advanced network settings > Network reset > Reset now. You may need to reinstall VPN software afterward.
- Android: on most phones the path is Settings > System > Reset options, then the option to reset Wi-Fi, mobile and Bluetooth. The name changes by manufacturer.
If nothing connects even then, Apple and Google both point you to your provider or the network’s administrator.
Frequently asked questions
Why does Wi-Fi say “incorrect password” when it’s right?
The device may be holding an outdated saved entry for the network. Forgetting the network and typing the password again usually helps. If it doesn’t, check whether the password was changed on the router.
I’m connected but have no internet. What is that?
The device joined the network, but the router has no internet access. Restart the modem and router, and call your provider if it continues.
Will resetting network settings delete my photos?
No. Apple explains that it removes Wi-Fi networks, passwords, cellular and VPN settings, not your files.
Only one device won’t connect. What now?
Restart it, forget the network, try the other band and update the software. If only that device fails, the router is probably fine.
