Your phone isn't connecting because of a mismatch between what your phone thinks and what your router knows
When your phone won't connect to WiFi, the problem is almost always one of four things: your phone has the wrong password saved, your router isn't broadcasting its name, your phone is too far away, or your router needs to be restarted. Start by checking the simplest cause first — whether your phone has the correct password stored. Go to your phone's WiFi settings, find your network name, and look for an option that says "Forget" or "Remove". Tap it, then reconnect by entering your password again, character by character. Passwords are case-sensitive, so capital letters matter.
If that doesn't work, restart your router by unplugging it for 30 seconds, then plugging it back in. While it restarts (usually two to three minutes), restart your phone too by turning it off and back on. These two restarts together fix the majority of connection problems because they clear out temporary settings that have gotten confused.
Key Takeaways
- The most common fix is to forget your network in your phone's WiFi settings and reconnect with your password typed in again, because saved passwords can become corrupted.
- Restarting both your router and your phone clears temporary settings that prevent connection and should be your second step if forgetting the network doesn't work.
- Your phone may be too far from the router or blocked by thick walls, microwaves, or cordless phones that interfere with the WiFi signal.
- If your network name doesn't appear in your phone's list of available networks, your router may have stopped broadcasting it, which you can fix in your router's settings.
Check whether your phone is in range of the router
WiFi has a limited range, usually 30 to 50 feet in open space, but walls, floors, and certain appliances reduce that distance. If your phone connects fine in one room but not another, distance is likely the problem. Move closer to the router and try connecting again. If it works nearby but not in the other room, you may need to move your router to a more central location in your home, or you may need a second router or WiFi extender to reach that far corner.
Microwaves, cordless phones, baby monitors, and some older wireless devices broadcast on the same frequency as WiFi and can jam the signal. If your phone won't connect in the kitchen but connects elsewhere, a microwave running nearby could be the cause. Try connecting when the microwave is off, or move the router away from the kitchen.
Restart your router the correct way
Most people restart their router by flipping the power switch, but the correct method is to unplug the power cable from the back of the router itself. Leave it unplugged for a full 30 seconds — this clears the router's memory. Then plug it back in and wait two to three minutes for all the lights to stabilize before trying to connect again.
If restarting doesn't work and you've already forgotten and re-entered your password, check whether your router is still broadcasting your network name. On your phone, go to WiFi settings and look at the list of available networks. If your network name doesn't appear at all, your router may have stopped broadcasting. Log into your router's settings (usually by typing 192.168.1.1 into a web browser on a computer connected to the router) and look for a setting called "SSID Broadcast" or "Network Name Broadcast". Make sure it is turned on.
Check your router's WiFi band setting
Routers broadcast on two different frequencies: 2.4 GHz and 5 GHz. Older phones only connect to 2.4 GHz, while newer phones can use either. If your router is set to broadcast only on 5 GHz, an older phone won't see the network at all. Check your router's settings to confirm it is broadcasting on both bands, or at minimum on 2.4 GHz.
Some routers let you create separate network names for each band — you might see "YourNetwork" and "YourNetwork-5G" as two different options. If your phone is older, connect to the one without "-5G" in the name. Newer phones usually connect faster on 5 GHz, so if you have a choice, try that first.
Look for a WiFi password you may have changed
If you changed your router's password at some point, your phone still has the old one saved. Go to your phone's WiFi settings, find your network name, and select "Forget Network" or "Remove". Then reconnect and enter your current password. Type it slowly and carefully — most passwords are case-sensitive, meaning capital A is different from lowercase a.
If you don't remember your current password, you can reset it by logging into your router's settings page. The default address is usually 192.168.1.1 or 192.168.0.1, which you type into a web browser on a computer. You'll need the router's admin username and password, which are often printed on a sticker on the back of the router. Once you're logged in, look for a WiFi settings or Security section and change the password to something you'll remember.
Restart your phone and check for software updates
A straightforward restart of your phone often fixes WiFi connection problems. Turn your phone completely off, wait 10 seconds, and turn it back on. This clears temporary settings that may be preventing connection.
If your phone still won't connect after restarting, check whether your phone's operating system is up to date. Older software versions sometimes have bugs that prevent WiFi from working correctly. Go to your phone's Settings, find System or About Phone, and look for an option to check for updates. Install any available updates and restart your phone afterward.
When to reset your network settings
If you've tried forgetting the network, restarting both devices, and checking your password, and your phone still won't connect, you can reset your phone's network settings. This erases all saved WiFi networks and passwords from your phone, so you'll need to reconnect to everything afterward. On an iPhone, go to Settings > General > Reset > Reset Network Settings. On Android, go to Settings > System > Reset Options > Reset WiFi, Mobile & Bluetooth.
After the reset, your phone will restart. Go back to your WiFi settings, find your network name, and enter your password again. This usually works when something in your phone's network memory has become corrupted and a straightforward restart won't fix it.
Frequently Asked Questions
Why does my phone connect to WiFi but the internet doesn't work?
Your phone is connected to the router but the router itself doesn't have internet. Restart your modem (the device your internet provider gave you) by unplugging it for 30 seconds, then plug it back in and wait three minutes. If that doesn't work, contact your internet provider to check whether there's an outage in your area.
My phone connects but keeps disconnecting every few minutes
This usually means your phone is at the edge of the WiFi range and the signal is weak. Move closer to the router or restart both your phone and router. If it keeps happening in the same spot, your router may need to be moved to a more central location, or you may need a WiFi extender to reach that area.
Can I connect to WiFi if I don't know the password?
No, you need the correct password to connect. If you don't know it, check whether it's written on a sticker on the back of your router. If not, you can reset your router to its factory settings by holding down a small reset button on the back for 10 seconds, but this will erase all your settings and you'll have to set it up again from the beginning.
Why does my phone say the WiFi password is wrong when I know it's correct?
Passwords are case-sensitive, so check that capital and lowercase letters match exactly. Also make sure you're not accidentally typing a space at the beginning or end. If you're still stuck, reset your router's password by logging into its settings page at 192.168.1.1 and creating a new one.
Does my phone need to be restarted every time I want to use WiFi?
No. Once you've connected successfully, your phone should remember the network and connect automatically when you're in range. If your phone keeps forgetting the network, try forgetting it and reconnecting once more, or reset your phone's network settings.
