Your phone can't connect to WiFi because of a mismatch between what your phone is trying to do and what your router is set up to allow
The most common reasons are: your phone has the wrong password saved, your router has stopped broadcasting the network name, your phone is too far away or blocked by walls, your router needs to be restarted, or your phone's WiFi radio needs to be turned off and back on. Most of these take under five minutes to fix. Start with the simplest step first — turning WiFi off and back on on your phone — because it clears temporary glitches that look like bigger problems.
If that doesn't work, the next step depends on whether your phone can see your network name at all. If you can see it but can't connect, the problem is almost always the password. If you can't see the network name, the problem is almost always the router.
Key Takeaways
- Restart your phone's WiFi by turning it off for ten seconds, then back on — this fixes most connection problems without touching anything else.
- If your phone sees the network but won't connect, forget the network and reconnect with the correct password, because your phone has the wrong one saved.
- If your phone doesn't see the network at all, restart your router by unplugging it for thirty seconds, waiting for all lights to stop blinking, then plugging it back in.
- If restarting doesn't work, move your phone closer to the router to rule out distance or walls blocking the signal.
- If your phone still won't connect after these steps, check whether other devices can connect — if they can, the problem is your phone's WiFi settings, not your router.
Turn WiFi off and back on on your phone
Open your phone's settings and find the WiFi toggle. On iPhone, swipe down from the top right corner to open Control Center and tap the WiFi icon. On Android, swipe down twice from the top to open Quick Settings and tap WiFi. Turn it completely off, wait ten seconds, then turn it back on.
This step clears a temporary error in your phone's WiFi radio — the part of your phone that talks to the router. It's the same reason restarting a computer fixes most problems. Wait the full ten seconds; turning it off and when ready back on doesn't always work.
After you turn WiFi back on, your phone will scan for networks. Look at the list and see if your network name appears. If it does and you can connect, you're done. If it does but you still can't connect, move to the next section. If it doesn't appear at all, skip to the section about restarting your router.
Forget the network and reconnect with the correct password
If your phone sees your network name but won't connect, your phone has the wrong password saved. This happens when someone types the password wrong the first time, or when you changed your router's password but your phone still has the old one.
On iPhone: go to Settings > WiFi, tap the network name, then tap "Forget This Network". On Android: go to Settings > WiFi, press and hold the network name, then tap "Forget". Your phone will remove the saved password.
Now tap your network name again and type the password. The password is on a sticker on the bottom or back of your router, or in the manual that came with it. Type it exactly as it appears — passwords are case-sensitive, meaning capital letters matter. If you're not sure, check the sticker again before you tap Connect.
If you changed your router's password and don't remember the new one, you'll need to reset your router to its factory settings. This erases all your settings and returns it to the password on the sticker. Unplug the router, press and hold the small reset button on the back for ten seconds while it's unplugged, then plug it back in. The network will reappear with the original password from the sticker.
Restart your router if your phone can't see the network
If your phone doesn't see your network name in the list of available networks, your router has stopped broadcasting it. The fastest fix is to restart the router.
Unplug the power cable from the back of your router. Wait thirty seconds — this is longer than it feels, but it matters because the router needs time to fully shut down. While you wait, all the lights on the router will go dark. Plug the power cable back in.
The router will take one to three minutes to start up. You'll see lights begin to blink. Wait until the lights stop changing — usually a solid light or a slow blink means it's ready. Then check your phone's WiFi list again. Your network name should appear.
If the network still doesn't appear after the router has fully started up, move to the next section.
Check the distance between your phone and router
WiFi signals weaken as they travel through walls, floors, and distance. If your phone is in a bedroom on the opposite end of the house from your router, or if the router is in a closet, the signal might be too weak to connect.
Walk your phone closer to the router — ideally within the same room — and check the WiFi list again. If your network name appears now, the problem is distance or walls. You can move your router to a more central location, or move it higher up (on a shelf or wall mount rather than on the floor), because height helps the signal reach more of your home.
If your network name still doesn't appear even when your phone is right next to the router, the problem is your router itself, not the distance.
Check whether other devices can connect
Borrow another phone, tablet, or laptop and try to connect it to your WiFi. If the other device connects without trouble, the problem is your phone's WiFi settings, not your router or network. If the other device also can't connect, the problem is your router.
If your phone is the only device that won't connect, try restarting your phone completely — not just turning WiFi off and on, but powering the phone all the way down and back up. On iPhone, hold the power button until "slide to power off" appears, then slide. On Android, hold the power button and tap "Power off". Wait ten seconds, then hold the power button again to turn it back on.
After your phone restarts, go to Settings > WiFi, find your network, and try to connect again with the correct password. If it still won't connect, your phone may have a deeper WiFi problem that requires a factory reset or a visit to the phone maker's support line.
Check your router's settings if multiple devices won't connect
If other devices also can't see or connect to your network, log into your router's settings to check what's happening. Open a web browser on a computer or tablet that's connected to WiFi or ethernet, and type the router's address into the address bar. The address is usually printed on the sticker on the router — it looks like 192.168.1.1 or 192.168.0.1.
Log in with the username and password from the sticker (often "admin" and "admin", or "admin" and the WiFi password). Look for a setting called "WiFi" or "Wireless" and check that it's turned on. Some routers have separate toggles for 2.4 GHz and 5 GHz networks — make sure at least one is on. If WiFi is off, turn it on and wait for the network to appear on your phone.
If you're not comfortable logging into the router settings, or if WiFi is already on, restart the router again and wait the full three minutes for it to start up completely. If it still doesn't work after that, contact your internet provider — the problem may be with the router itself or with your internet service.
Frequently Asked Questions
Why does my phone connect to WiFi but then disconnect after a few minutes?
Your phone is probably moving out of range or the signal is being blocked. Try moving closer to the router. If it stays connected when you're near the router but disconnects when you move away, the problem is distance or walls. You may need to move your router to a more central location or add a WiFi extender to reach that area of your home.
My phone says "can't connect to this network" — what does that mean?
Your phone can see the network but the password is wrong, or there's a setting on your router that's blocking your phone. Forget the network and reconnect with the password from the sticker on your router. If that doesn't work, restart your router and try again.
How do I know if my router is broken?
If other devices can't connect either, and restarting the router doesn't fix it, the router may be broken. Check that the power cable is plugged in firmly and that the outlet works by plugging in another device. If the router still won't turn on or broadcast a network after a full restart, contact your internet provider — they may replace it for free.
Can I connect to WiFi if I'm outside my house?
No — your home WiFi only broadcasts within range of your router, usually 100 to 150 feet depending on walls and obstacles. Once you're outside that range, you'll need to use cellular data or find another WiFi network. If you need WiFi throughout your property, you may need a WiFi extender or a mesh system.
Why does my phone keep asking for the password even though I already entered it?
Your phone didn't save the password correctly, usually because you typed it wrong the first time. Forget the network, then reconnect and type the password more slowly, checking each letter against the sticker. Make sure Caps Lock is off unless the password actually has capital letters.
