If WiFi is not working on your phone but working on other devices, your internet service and router are fine, and the cause is either a setting on the phone or a router setting that affects only that phone. Start by forgetting the network on the phone and rejoining it with the correct password. If that does not work, the causes to check are a VPN or DNS setting, a private MAC address the router does not recognize, a router security mode the phone cannot use, or a pause placed on the phone in the router's app.
This guide covers iPhones running iOS 18 through iOS 27 and Android phones running Android 10 through Android 17, including Google Pixel and Samsung Galaxy models, on a home WiFi network where at least one other device is online. Menu paths were checked against Apple, Google, and Samsung support pages on October 8, 2026. Other Android phones use similar names in slightly different places.
Key Takeaways
- When other devices are online, the internet connection and the router are working. The problem is the phone's saved network settings or a router setting that singles out that phone.
- The symptom points to the cause. A rejected password means a saved password or security mismatch, a missing network name means a band the phone cannot use or a hidden network, and "connected, no internet" means a VPN, a DNS setting, or a paused device.
- Resetting network settings is the last step to try on the phone. It erases saved WiFi networks and passwords and leaves photos, apps, and messages alone.
Is the Problem Your Phone or Your Router?
If another device can use the same WiFi network, the router and the internet connection are working, and the problem is on the phone or in how the router treats that phone. Two tests from Google's WiFi troubleshooting page narrow it down further:
- Join a different WiFi network with the phone. A friend's network, a work network, or another phone's hotspot all count. If the phone works there, its WiFi hardware is fine and the trouble is between the phone and your home network.
- Check a second device on your home network. If a laptop or another phone loads websites on the same network name, the network is fine and the problem is the first phone.
Find the row that matches what your phone shows, then go to that section below.
| What the phone shows | Most likely cause | Where to start |
|---|---|---|
| "Incorrect password," or it keeps asking for the password | Likely cause: The saved password is wrong, or the router uses a security mode the phone does not support | Start here: Forget the network and retype the password, then check the router's security mode |
| Your network name is missing, but other devices see it | Likely cause: The network is on a band the phone cannot use, or the name is hidden | Start here: Check which bands the phone supports and turn off the hidden network setting |
| Stuck on "Connecting" or "Obtaining IP address" | Likely cause: The router is refusing the phone or not assigning it an address | Start here: Restart the router, then check MAC filtering and blocked devices |
| Connected, but nothing loads | Likely cause: A VPN, a DNS setting, the wrong date and time, or a pause in the router app | Start here: Turn off the VPN, set DNS to automatic, and check the router app |
| Connects, then drops again and again | Likely cause: Weak signal where you use the phone, or the phone is switching to cellular data | Start here: Test in the same room as the router, then check Connectivity Assist or Adaptive connectivity |
| Works on other WiFi networks, fails only at home | Likely cause: Outdated saved settings on the phone, or a router setting aimed at that phone | Start here: Forget and rejoin, then read the private MAC address section |
| Fails on every WiFi network | Likely cause: The phone's software or its WiFi hardware | Start here: Update the phone, reset network settings, then contact the manufacturer |
If every device in the house loses its connection, the phone is not the cause. Our guide to fixing WiFi that keeps disconnecting covers that situation. If the phone fails only on hotel, airport, or cafe networks, the sign-in page is the usual obstacle, and our public WiFi guide covers it.
Quick Fixes to Try First
Forgetting the network and rejoining it clears a wrong saved password and outdated saved settings without changing anything on the router, so it is the first fix to try. Work through these in order and test the connection after each one.
- Check Airplane Mode and WiFi. Airplane Mode should be off and WiFi should be on. On an iPhone, a WiFi setting that is dimmed and cannot be tapped calls for a restart.
- Restart the phone. Power it off fully and turn it back on.
-
Forget the network and rejoin it. Retype the password by hand when the phone asks for it.
- iPhone: Settings, then Wi-Fi, then the More Info button next to the network, then Forget This Network.
- Google Pixel: Settings, then Network & internet, then Internet, then Saved networks. Select the network and tap Forget.
- Samsung Galaxy: Settings, then Connections, then Wi-Fi. Press and hold the network and tap Forget network.
- Move into the same room as the router. If the phone connects there and nowhere else, the problem is signal range and not a setting.
- Restart the router. Unplug its power cord, wait 30 seconds, and plug it back in. Our guide on how to restart your router has the full sequence for a separate modem and router.
- Install waiting updates. On an iPhone, open Settings, then General, then Software Update. On a Samsung Galaxy, open Settings, then Software update, then Check for updates. On other Android phones, search Settings for "system update."
Why Does My Phone Say the WiFi Password Is Incorrect?
A phone rejects a password for two reasons: the saved password is out of date or mistyped, or the router uses a security mode the phone cannot work with. Forget the network and type the password again before changing anything on the router.
- Check the password itself. WiFi passwords are case-sensitive. If someone in the house changed it, every other device was updated and the phone was missed. Our guide on how to change your WiFi password shows where to view or reset the current one.
- Check the network name. The network name, also called the SSID, can be nearly identical to a neighbor's. Compare it to the name on your router's label or in its app.
- Check the security mode. WPA2 and WPA3 are the security standards that encrypt a WiFi network. A router set to WPA3 only will turn away a phone that predates WPA3. The Wi-Fi Alliance has required WPA3 support in new Wi-Fi CERTIFIED devices since 2020, so phones older than that may not have it.
The fix for a security mismatch is the mixed mode, which routers label WPA2/WPA3 Transitional or WPA2/WPA3 Mixed. Apple's recommended router settings call for WPA3 Personal, or WPA2/WPA3 Transitional for compatibility with older devices. Do not drop the router to WPA, WEP, or TKIP to get one phone online. Apple lists all three as weak security.
Why Can't My Phone See My WiFi Network?
When other devices see the network and one phone does not, the router is broadcasting on a band that phone cannot use, or the network name is hidden. A band is a range of radio frequencies that WiFi uses: 2.4 GHz, 5 GHz, or 6 GHz.
- 6 GHz networks. Only WiFi 6E and WiFi 7 phones can see a 6 GHz network. Among iPhones, Apple lists the iPhone 15 Pro, iPhone 15 Pro Max, and later models, excluding the iPhone 15, iPhone 15 Plus, iPhone 16e, and iPhone 17e. If your router gives its 6 GHz band a separate name, a phone without 6 GHz will never list that name. Join the router's 2.4 GHz or 5 GHz name instead, or set one name for all bands.
- Hidden networks. A router with its network name hidden does not appear in the phone's list, and the name has to be typed in by hand. Apple recommends setting Hidden network to Disabled, and notes that hiding the name does not secure the network.
- 5 GHz range. The 5 GHz band reaches a shorter distance than 2.4 GHz. If the router uses separate names for each band and the phone only sees one of them, move closer and look again. Our explainer on 2.4 GHz vs 5 GHz covers how the bands differ.
Why Does My Phone Say Connected but No Internet?
If the phone shows it is connected to WiFi and other devices on the same network are online, something is blocking only that phone: a VPN, a DNS setting, the wrong date and time, or a pause set in the router's app. Check them in this order.
- VPN and security apps. A VPN (virtual private network) routes the phone's traffic through an encrypted connection to another server. When that connection fails, nothing loads. Apple's WiFi troubleshooting page says to uninstall VPN or security software, restart, and test. A VPN kill switch produces the same symptom on purpose: it blocks all traffic until the VPN reconnects.
- iCloud Private Relay (iPhone). If the phone shows a message that the network is not compatible with Private Relay, open Settings, then Wi-Fi, tap the More Info button next to the network, and turn off Limit IP Address Tracking for that network.
- DNS. DNS (Domain Name System) is the service that turns a website name into the numeric address a device connects to. On Android, open Settings, then Network & internet, then Private DNS. The options are Off, Automatic, and Private DNS provider hostname. If a hostname is entered there and the phone cannot reach it, set it to Automatic and test. On an iPhone, open Settings, then Wi-Fi, tap the More Info button next to the network, and set Configure DNS to Automatic. Our DNS guide covers choosing and setting a DNS provider once the connection works.
- Date and time. Google notes that an incorrect date or time can cause WiFi problems. On Android, open Settings, then System, then Date & time, and turn on Set time automatically.
- A pause or block in the router app. Router and ISP apps can pause the internet for one device or one family profile. Open the app, find the phone in the device list, and check that it is not paused, blocked, or on a schedule. Our router parental controls guide shows where these settings live.
Cellular data can hide a WiFi problem
Phones can switch to cellular data when WiFi is weak, so pages load and the WiFi fault goes unnoticed until cellular signal is poor. On iPhones running iOS 27, the feature is Connectivity Assist, which replaced Wi-Fi Assist. Apple's troubleshooting steps say to open Settings, tap Wi-Fi, and make sure Connectivity Assist is off while you test. On iOS 26 and earlier, the same feature is Wi-Fi Assist, in Cellular settings. On Pixel phones, the matching setting is Auto-switch to mobile network, under Settings, then Network & internet, then Adaptive connectivity.
Is a Private MAC Address Blocking My Phone?
A private MAC address blocks a phone only when the router uses MAC filtering, an allowed-devices list, or per-device parental controls. A MAC address is the hardware ID a device shows to a WiFi network. To protect privacy, phones show each network a made-up (private or randomized) address in place of the hardware one, and a router that filters by address treats a changed address as an unknown device.
- iPhone. Since iOS 18, Private Wi-Fi Address has three options: Off, Fixed, and Rotating. According to Apple, Fixed is the default for networks using WPA2 or stronger security, and Rotating changes the address every 2 weeks. After Reset Network Settings, the iPhone uses a different private address the next time it joins. That is why a phone the router allowed last month can be refused after a reset.
- Android. Android 10 and later use a randomized MAC address by default. Android's documentation says the address is tied to each saved network and stays the same until a factory reset.
Fix it on the router first, so the phone keeps its privacy protection:
- Allow the address the phone uses now. In the router's app or settings, find the phone in the device list and allow or unpause it. On Android, the address is shown as Randomized MAC address in the network's settings. Google advises adding both of the phone's MAC addresses when you set up network parental controls.
- Turn off MAC filtering. Apple recommends setting MAC address filtering to Disabled and says not to rely on it to keep people off a network. A WPA2 or WPA3 password does that job.
- Stop the address from changing. If you keep the filter, set the phone to use one address on your home network only. On an iPhone, open Settings, then Wi-Fi, tap the More Info button next to the network, tap Private Wi-Fi Address, and choose Fixed. On a Samsung Galaxy, the setting is MAC address type, with the options Randomized MAC and Phone MAC. On a Pixel, tap the settings icon next to the network to find the privacy setting. Leave private addresses on for public networks.
Which Router Settings Stop One Phone From Connecting?
The router settings to check when a single phone cannot connect are the security mode, MAC address filtering, the hidden network option, the network name on each band, and firmware updates. The values below come from Apple's recommended settings for WiFi routers and access points, published July 14, 2026.
| Router setting | Recommended value | Why it affects a phone |
|---|---|---|
| Security | Set to: WPA3 Personal, or WPA2/WPA3 Transitional for older devices | Why: A WPA3-only network turns away phones that predate WPA3 |
| Network name (SSID) | Set to: One name for all bands | Why: A phone cannot list or join a name that exists only on a band it lacks |
| Hidden network | Set to: Disabled | Why: A hidden name is missing from the phone's list and must be typed in by hand |
| MAC address filtering | Set to: Disabled | Why: Phones use private addresses, so a filter can refuse a phone it allowed before |
| Channel | Set to: Auto | Why: The router picks a channel for itself instead of staying on a crowded one |
| Channel width, 2.4 GHz | Set to: 20 MHz | Why: Apple recommends 20 MHz for the 2.4 GHz band |
| Channel width, 5 GHz and 6 GHz | Set to: Auto or all widths | Why: The router and phone agree on the widest channel both support |
| Automatic firmware updates | Set to: Enabled | Why: Apple and Samsung both list a router firmware update as a fix when a phone will not connect |
To reach these settings, open the router's app or its settings page in a web browser. Our guide on how to log into your router covers every major brand. If your router has no automatic channel option, our guide to the best WiFi channel for 2.4 GHz and 5 GHz shows how to pick one by hand.
How Do I Reset Network Settings on iPhone and Android?
Resetting network settings erases the phone's saved WiFi networks and passwords and returns its network options to their defaults. It does not delete photos, apps, or messages. Use it after the steps above have failed, and have your WiFi password ready, because the phone will ask for it again.
| Phone | Menu path | What it resets |
|---|---|---|
| iPhone | Path: Settings, General, Transfer or Reset iPhone, Reset, Reset Network Settings | Resets: All WiFi networks and passwords, cellular settings, and VPN and APN settings |
| Google Pixel | Path: Settings, System, Reset options, Reset Bluetooth & Wi-Fi, Reset settings | Resets: WiFi and Bluetooth settings |
| Samsung Galaxy | Path: Settings, General management, Reset, Reset Wi-Fi and Bluetooth settings, Reset settings | Resets: WiFi and Bluetooth settings |
Two notes before you reset. If a school or employer set up the phone, Apple says to check with the IT administrator first, because the reset removes work and school network configurations. And on an iPhone, the reset gives the phone a new private address, so a router with MAC filtering will need the new address allowed.
On Android there is one more test to run before a reset. Restart the phone in safe mode, which turns off downloaded apps, and try the WiFi again. Google and Samsung both say that if WiFi works in safe mode, a downloaded app is the cause. Uninstall recently added apps one at a time, newest first, and test after each.
When Is the Router the Problem?
The router is the likely cause when more than one device has trouble, when the phone works on every other WiFi network, or when the phone connects only in the same room as the router. In those cases, changing phone settings will not help.
- Update the router's firmware. Firmware is the software that runs the router. Apple and Samsung both list a router firmware update among the fixes for a phone that will not connect.
- Consider the router's age. WPA3 support has been required in new Wi-Fi CERTIFIED devices since 2020, so a router older than that may offer only WPA2 and may no longer receive updates. Our guide on how long routers last lists the signs that one is wearing out.
- Check coverage. If the phone connects near the router and fails in the rooms where you use it, the home needs more coverage, not different settings. Our comparison of a WiFi extender vs mesh explains which one fits.
- Factory reset the router last. A factory reset erases the WiFi name, password, and every custom setting. Our guide on restart vs. factory reset walks through it.

What's your WiFi problem?
When Is It the Phone's Hardware?
If the phone cannot join any WiFi network after a software update and a network settings reset, the fault is in the phone and not in any network. Each manufacturer has a next step.
- iPhone. Apple says that if the device cannot connect to any WiFi network, contact Apple.
- Samsung Galaxy. Open the Samsung Members app, tap Support, tap Get started, and select Wi-Fi to run the built-in test.
- Google Pixel. On Pixel 11 phones in the US, open Settings, then Device health & support, then Wi-Fi diagnostics.
Frequently Asked Questions
Why is my WiFi not working on my phone but working on other devices?
The network is fine and the cause is specific to the phone: a wrong saved password, outdated saved network settings, a VPN or DNS setting, or a router feature that is blocking that one device. Forget the network on the phone, rejoin it, and retype the password. If that fails, turn off any VPN and check the router's app for a paused or blocked device.
Why does my phone say connected but no internet when other devices work?
The phone has joined the router, but its traffic is being stopped on the way out. The usual causes are a VPN that cannot connect, a Private DNS hostname the phone cannot reach, the wrong date and time, or a pause set for that phone in the router or ISP app. Turn off the VPN, set DNS to automatic, and check the app.
Why won't my iPhone connect to WiFi when everything else does?
Start in Settings under Wi-Fi: confirm WiFi is on, Airplane Mode is off, and Connectivity Assist is off while you test. Then forget the network and rejoin it. If the iPhone still cannot connect, Apple's steps are to remove VPN or security software, update the router's firmware, and then use Reset Network Settings.
Why won't my Android phone connect to WiFi?
Forget the network and add it again, confirm the date and time are set automatically, and set Private DNS to Automatic. If WiFi works in safe mode, a downloaded app is the cause. The last phone-side step is the network reset: Reset Bluetooth & Wi-Fi on a Pixel, or Reset Wi-Fi and Bluetooth settings on a Samsung Galaxy.
Will resetting network settings delete my photos or apps?
No. On an iPhone, Reset Network Settings resets all WiFi networks and passwords, cellular settings, and VPN and APN settings. On Pixel and Samsung phones, the reset covers WiFi and Bluetooth settings. Photos, apps, and messages stay on the phone, and you will need to re-enter WiFi passwords afterward.
Should I turn off Private Wi-Fi Address on my iPhone?
Apple recommends keeping it on and installing the latest software updates before deciding to turn it off. If your router filters devices by MAC address, set Private Wi-Fi Address to Fixed for your home network, so the address stops changing, or turn off MAC filtering on the router.
Can a router block one phone and not the others?
Yes. MAC address filtering, an allowed-devices list, a parental control profile, or a pause button in the router or ISP app can each stop a single phone while every other device stays online. A WPA3-only security setting can also turn away an older phone that does not support WPA3.
Why can't my phone see my 6 GHz WiFi network?
Only WiFi 6E and WiFi 7 phones have a 6 GHz radio. Among iPhones, that means the iPhone 15 Pro, iPhone 15 Pro Max, and later models, excluding the iPhone 15, iPhone 15 Plus, iPhone 16e, and iPhone 17e. Join the router's 2.4 GHz or 5 GHz network, or set the router to use one name for all bands.
