The most common reason your iPhone won't connect is that WiFi is turned off or your phone has forgotten the network
Start by checking whether WiFi is actually on. Swipe down from the top-right corner of your screen to open Control Center, and look for the WiFi icon. If it's grayed out, tap it to turn WiFi back on. If the icon is already blue and active, your WiFi is on but something else is blocking the connection.
Next, check whether your iPhone remembers this network. Go to Settings, then WiFi, and look for your network name in the list. If you see it, tap it and select "Forget This Network," then tap the network name again and enter your WiFi password. This forces your phone to reconnect from scratch, which fixes most connection problems. If your network doesn't appear in the list at all, your phone isn't detecting it — move to the next section.
If you've already entered the password and your phone still won't connect, try restarting your iPhone. Hold the power button and either volume button until the power-off slider appears, then drag it to turn off your phone. Wait 10 seconds, then press the power button again to turn it back on. Restart your WiFi router at the same time by unplugging it for 30 seconds, then plugging it back in.
Key Takeaways
- Check Control Center to confirm WiFi is turned on, not just available.
- Forget the network in Settings and re-enter your password to force a fresh connection.
- Restart both your iPhone and your WiFi router by powering them off and back on.
- Move closer to your router to rule out weak signal as the cause.
- If your network doesn't appear in the list, your router may not be broadcasting its name, or interference is blocking the signal.
Your network name doesn't show up in the available networks list
If you don't see your network name when you open Settings > WiFi, your router is either off, too far away, or not broadcasting its name. First, check that your router is powered on — look for a light on the front. If it's off, plug it in and wait two minutes for it to fully start up.
If the router is on, move your iPhone closer to it. WiFi signal weakens with distance and through walls. If your network appears when you're near the router but disappears when you move away, you have a signal problem, not a connection problem — see the section on weak signal below.
If your network still doesn't appear even when you're close to the router, your router may have SSID broadcast turned off. This is a security setting that hides your network name from the available networks list. You can still connect to it manually. Go to Settings > WiFi, tap "Other," enter your exact network name, choose your security type (usually WPA2 or WPA3), and enter your password. If you don't know your network name or password, check the sticker on the back or bottom of your router.
Your iPhone connects but the internet doesn't work
If your phone shows a checkmark next to your network name but web pages won't load and apps show no connection, your iPhone is connected to the router but the router itself isn't connected to the internet. This is a router problem, not an iPhone problem.
Check your router's lights. Most routers have an internet light or WAN light that should be solid or blinking. If it's off or red, your internet service is down. Restart your router by unplugging it for 30 seconds and plugging it back in. Wait two minutes for it to fully restart, then try loading a web page on your iPhone.
If the internet light is on but your iPhone still has no connection, restart your iPhone and forget the network, then reconnect. If that doesn't work, your router may need a factory reset or a firmware update — contact your internet provider or check your router's manual for these steps.
Your iPhone keeps disconnecting from WiFi
If your phone connects but then drops the connection every few minutes, the problem is usually weak signal, interference, or a setting on your iPhone. First, move closer to your router. If the disconnections stop, weak signal is the cause. You may need to move your router to a more central location or add a WiFi extender to reach that part of your home.
If you're already close to the router, check whether WiFi information is turned on. This setting automatically switches your phone to cellular data when WiFi signal is weak, which can feel like disconnection. Go to Settings > Cellular (or Mobile Data), scroll down, and toggle off WiFi information. This prevents your phone from switching networks automatically.
Interference from other devices can also cause disconnections. WiFi routers use the 2.4 GHz or 5 GHz frequency band, and other devices like microwaves, cordless phones, and baby monitors use the same frequencies. Try moving your router away from these devices, or switch to a different WiFi channel in your router's settings. Most routers have a mobile app or a web interface (usually accessed by typing your router's IP address into a browser) where you can change the channel.
Your WiFi password isn't working even though you know it's correct
If you're certain your password is right but your iPhone won't accept it, the problem is usually a typo, a caps lock issue, or a mismatch between what you think your password is and what your router actually has set.
First, double-check that Caps Lock is off on your iPhone keyboard. Passwords are case-sensitive, so "MyPassword" is different from "mypassword." If you're not sure what your password is, you can find it on the sticker attached to your router — it's usually labeled "WiFi Password," "Network Key," or "Passphrase." If the sticker is missing or unreadable, you can reset your router to its factory settings, which resets the password to the one on the sticker. This erases all your custom settings, so only do this if you're willing to set up your router again from scratch.
If you've recently changed your WiFi password, make sure all your devices are using the new one. Your iPhone may be trying to connect with the old password. Forget the network, restart your iPhone, and reconnect using the new password.
Your iPhone connects to WiFi but it's very slow
Slow WiFi usually means weak signal, too many devices connected, or interference. Move closer to your router first — if speed improves, weak signal is the problem. If you're already close, check how many devices are connected. Go to your router's settings (usually through a mobile app or by typing the router's IP address into a web browser) and look at the connected devices list. If dozens of devices are connected, some may be old devices you've forgotten about. Disconnect any you don't recognize or don't use regularly.
Interference from other networks can also slow your connection. If you live in an apartment or dense neighborhood, your router may be on the same WiFi channel as your neighbors' routers. Use a WiFi analyzer app (search "WiFi analyzer" in the App Store) to see which channels nearby networks are using, then log into your router and switch to a less crowded channel.
Your iPhone won't connect to a public WiFi network
Public networks at coffee shops, airports, and libraries often require you to open a web browser and log in or accept terms before you can use the internet. If your iPhone connects to the network but shows no internet, this login page may not be loading.
Open Safari or another web browser and try to visit any website. A login page should appear automatically. If it doesn't, try typing a straightforward address like "example.com" into the address bar. If a login page still doesn't appear, the network may require you to use a specific app or to scan a QR code. Ask the staff at the location.
If you've already logged in but still have no internet, try forgetting the network and reconnecting. Some public networks have connection issues on certain devices. If that doesn't work, try connecting to a different network if one is available, or use your phone's cellular data instead.
Frequently Asked Questions
How do I know if my WiFi password is wrong?
Your iPhone will show an error message saying "Unable to Join Network" or "Incorrect Password" when you try to connect. If you see this message, the password you entered doesn't match what the router has stored. Check the password on the router's sticker, or reset the router to factory settings to restore the default password.
Will restarting my router erase my WiFi settings?
No. Restarting your router by unplugging it for 30 seconds and plugging it back in does not erase any settings. Your network name and password stay the same. A factory reset is different — that erases everything and restores the router to its original state, which you should only do if you're willing to set it up again from scratch.
Why does my iPhone connect to WiFi at home but not at work or a friend's house?
The most common reason is that you're entering the password wrong, or the network uses a security type your iPhone doesn't support. Try forgetting the network and reconnecting with the password written down in front of you. If the network uses an older security standard like WEP, your iPhone may not support it — ask the network owner to upgrade to WPA2 or WPA3.
Can I connect to WiFi if I don't have cellular service?
Yes. WiFi and cellular are separate connections. You can use WiFi to browse the internet, send messages, and make calls over WiFi even if you have no cellular signal. You won't be able to make regular phone calls without cellular service, but WiFi calling works if your carrier supports it.
What should I do if nothing I've tried works?
Try a full restart of your iPhone: hold the power button and either volume button until the power-off slider appears, drag it to turn off your phone, wait 10 seconds, then press the power button to turn it back on. If that doesn't work, your router may have a hardware problem. Contact your internet provider to report the issue, or take your router to a retailer for diagnosis.
