Your Android phone connected to Wi-Fi just fine yesterday, and now it refuses to join the network. I have been in that exact spot, and it is frustrating when every other device in the house works perfectly while your phone sits there stuck on “Obtaining IP address.”
In this guide, I will walk you through why your Android phone Wi-Fi is not connecting and what to do about it, starting with 30-second fixes and moving all the way up to deeper troubleshooting if the easy steps do not work.
Most Wi-Fi problems on Android come from software glitches, stale network profiles, router hiccups, or conflicts that appeared after a recent Android update. By the end of this article, you will know exactly how to fix Wi-Fi on your Android phone or figure out whether it is time to call your internet provider.
Why won’t my Android phone connect to Wi-Fi anymore?
In most cases, the cause is a temporary software glitch, a changed Wi-Fi password, a router-side issue, or a conflict that showed up right after an Android update. Your phone stores network profiles, and when one of those profiles becomes corrupt, the connection fails even though the network still appears in your list.
Physical distance, thick walls, and interference from Bluetooth or other electronics can also weaken the signal enough that your phone drops the connection or refuses to join. Sometimes the problem lives on the router side, such as a stuck DHCP lease or MAC address filtering that blocks your phone from getting an IP address.
Understanding which of these is happening is the first step to a fast fix, so the next section helps you figure that out.
Is it your phone or your network?
Start by testing another device on the same Wi-Fi network. If your laptop, tablet, or smart TV connects without trouble, the problem is almost certainly isolated to your Android phone.
If every device in your home struggles, unplug your router and modem for 30 seconds before doing anything else. You can also try connecting your phone to a different network, such as a mobile hotspot or a friend’s Wi-Fi. If it works elsewhere, your home network is the culprit.
When only your phone fails, pay attention to the exact symptom. Does it say “Saved, Secured” but never connect? Does it get stuck on “Obtaining IP address”? Is the Wi-Fi toggle greyed out and unresponsive? Each symptom points to a different fix, and the steps below are ordered from quickest to deepest.
Quick fixes to try first
These four steps take less than two minutes combined, and they solve a surprising number of Android Wi-Fi connection problems on their own.
Toggle Wi-Fi off and on to refresh the connection
Swipe down from the top of your screen to open Quick Settings. Tap the Wi-Fi icon to turn it off, wait about five seconds, then tap it again to turn it back on.
This forces your phone to scan for networks again and clears a stale connection attempt. If the icon is greyed out and will not move, skip ahead to the Android 15, 16, and 17 section.
Cycle Airplane mode to reset all radios
Open Quick Settings and tap Airplane mode to enable it. Wait 10 seconds, then tap it again to turn it back off.
Airplane mode disables every radio at once, including Wi-Fi, mobile data, and Bluetooth. Cycling it often refreshes the wireless stack and resolves minor Android network issues that a simple Wi-Fi toggle cannot reach.
Restart your Android phone to clear temporary glitches
Press and hold the power button, then tap Restart. If your device only offers Power off, choose that and turn the phone back on after 30 seconds.
A restart clears temporary files and refreshes the background services that manage Wi-Fi. I have seen this single step bring back connections that looked completely dead.
Forget the network and reconnect with the correct password
Go to Settings, then Network & Internet, then Internet. Tap the saved network name and choose Forget. Then select the network again and enter the password.
This removes the stored profile that may contain outdated security settings. It is one of the most reliable ways to fix Wi-Fi authentication errors on Android, especially after a router password change.
Intermediate fixes when quick steps fail
If the fast fixes do not restore your connection, these slightly deeper checks target passwords, interference, apps, and system settings.
Check your Wi-Fi password for recent changes
A wrong password is more common than people admit. Ask whoever manages the router, or check the sticker on the router itself if the password has never been changed.
If the router password was updated recently, your phone still has the old one saved. Forgetting the network and re-entering the correct password usually solves this in seconds.
Move closer to the router to rule out signal issues
Walk within 10 feet of your router and try connecting again. If the signal is weak, your phone may refuse to connect even when the network name shows up in your list.
Look at the Wi-Fi icon in your status bar. Fewer bars mean a weaker signal, and a borderline signal is often enough to stop a connection from completing.
Turn off Bluetooth to avoid 2.4GHz interference
Bluetooth and Wi-Fi can interfere with each other on the 2.4GHz band. Swipe down to Quick Settings and turn Bluetooth off temporarily while you test.
If your Wi-Fi starts working the moment Bluetooth is off, the two radios were competing. You can leave Bluetooth off while troubleshooting, or switch your phone to the 5GHz band if your router supports it.
Disable battery saver mode so Wi-Fi can scan freely
Battery saver can restrict background network activity. Go to Settings, then Battery, and turn off Battery saver or Power saving mode.
Some aggressive battery modes pause Wi-Fi scanning entirely, which makes your phone behave as if it cannot find any networks at all. After disabling it, wait a minute and check again.
Disconnect active VPN profiles that may block traffic
An active VPN can cause Wi-Fi connection failures if its configuration is outdated or stuck. Go to Settings, then Network & Internet, then VPN, and disconnect any active connection.
If disconnecting the VPN fixes the issue, update the VPN app or switch to a different server. Several Reddit users have reported that a stuck VPN profile was the real reason their phone refused to connect to Wi-Fi.
Boot into safe mode to find a problematic app
Safe mode disables third-party apps, which helps you spot whether an app is interfering. Press and hold the power button, then press and hold the Power off option until the safe mode prompt appears. Tap OK to confirm.
If Wi-Fi works in safe mode, a recently installed app is likely the cause. Uninstall apps one at a time, starting with the most recent, until the problem disappears.
Free up storage space so network services run properly
When your phone is nearly full, system services can start misbehaving. Go to Settings, then Storage, and check how much free space is left.
If you are below about 10 percent free, delete unused apps, clear cached data, or move photos to cloud storage. I have seen low storage cause everything from sluggish apps to “Wi-Fi keeps dropping” symptoms that vanish once space is freed up.
Update Android OS to patch known Wi-Fi bugs
Software updates frequently include Wi-Fi fixes. Go to Settings, then System, then System update, and tap Check for update.
Install any pending security or system patches. In 2026, Android 15 and 16 devices received updates that specifically addressed Wi-Fi authentication errors and DHCP problems.
Advanced fixes for stubborn Wi-Fi problems
When the easier steps fail, these methods target deeper network settings and router-side issues.
Restart your router and modem to refresh the network
Unplug both your router and modem from power. Wait 30 seconds, plug the modem back in first, then plug the router back in after another 30 seconds.
This refreshes DHCP leases and clears router-side glitches. If your phone connects right after the router restarts, the issue was never with your phone in the first place.
Reset network settings to remove corrupt profiles
Go to Settings, then System, then Reset options, then Reset Wi-Fi, mobile & Bluetooth. Tap Reset settings and confirm.
This wipes all saved Wi-Fi networks, Bluetooth pairings, and VPN profiles, so you will need to re-enter Wi-Fi passwords afterward. Back up any VPN credentials first, because this fix solves corrupt network profiles better than almost anything else.
Switch to static IP or change DNS on Samsung phones
Samsung Galaxy users often fix “Obtaining IP address” loops by switching from DHCP to static. Go to Settings, then Connections, then Wi-Fi, tap the gear icon next to your network, then open IP settings.
Choose Static and enter an IP address inside your router’s range, such as 192.168.1.150. Set the gateway to your router’s IP, usually 192.168.1.1, and use 8.8.8.8 for DNS. Save the changes and reconnect. This DNS fix came up repeatedly in Samsung-focused forum threads.
Remove your phone case to improve antenna reception
Some thick or metal-lined cases block the Wi-Fi antennas built into your phone. Take the case off and test the connection.
It sounds too simple to matter, but forum users have reported this exact step fixing weak signals and dropped connections. If the case is the cause, switch to a thinner plastic design.
Factory reset your phone only as a last resort
If nothing else has worked, back up your data and perform a factory reset. Go to Settings, then System, then Reset options, then Erase all data (factory reset).
This wipes everything and restores the phone to its original state. Only take this step after you have ruled out the router and other devices, because setting everything back up takes significant time.
Android 15, 16, and 17 Wi-Fi issues
Recent Android updates have introduced specific Wi-Fi bugs. In 2026, some Pixel owners reported that Wi-Fi stopped working after an Android 15 update, while Samsung Galaxy users saw greyed-out Wi-Fi toggles after One UI patches.
If your problems started right after a system update, check Settings for a newer patch. Google and Samsung typically release follow-up fixes within days or weeks when a widespread bug is confirmed.
On Pixel phones, booting into safe mode after an update can confirm whether a system app is misbehaving. On Samsung devices, wiping the cache partition from recovery mode sometimes clears update-related Wi-Fi glitches without touching your personal data.
When the Wi-Fi toggle stays completely greyed out and will not turn on, it often points to a software or hardware issue that needs manufacturer support. Note exactly when the problem started and any updates you installed recently before reaching out.
When to contact your ISP or manufacturer
Contact your internet provider if every device in your home loses internet or if the router keeps needing restarts. They can check signal levels, replace faulty equipment, and reset things on their end.
Contact your phone manufacturer if your Android connects everywhere except your home network after trying every step above, or if the Wi-Fi toggle is greyed out and unresponsive. Hardware antenna damage is rare but possible after drops or liquid exposure.
Before you call, gather your phone model, Android version, and a short list of the steps you already tried. This saves time on the call and gets you to a real solution faster.
FAQs
How to fix Android phone not connecting to Wi-Fi?
Toggle Wi-Fi off and on, cycle Airplane mode, restart your phone, forget and reconnect to the network, then check your password. If those fail, restart your router and reset network settings under Settings, System, Reset options.
Why did my phone suddenly stop connecting to Wi-Fi?
The most common reasons are a temporary software glitch, a router that needs restarting, a recently changed Wi-Fi password, or a conflict that appeared after an Android update. A corrupt saved network profile can also cause a sudden failure.
Why won’t my phone connect to Wi-Fi but other devices will?
If other devices connect, the issue is isolated to your phone. Forget the network and reconnect, check for a VPN or battery saver blocking scanning, boot into safe mode to rule out a bad app, then reset network settings to clear any corrupt profile.
How to restore Wi-Fi settings in Android?
Go to Settings, System, Reset options, then Reset Wi-Fi, mobile and Bluetooth. This removes all saved networks and pairings so you can re-enter your Wi-Fi password cleanly. It is the most reliable fix for a corrupt network profile.
Why is my Wi-Fi greyed out and won’t turn on?
A greyed-out Wi-Fi toggle usually points to a software glitch after an update, a conflicting app, or hardware antenna damage. Try restarting the phone, booting into safe mode, installing any pending system update, and wiping the cache partition on Samsung devices. If it stays greyed out, contact the manufacturer.
What does ‘Obtaining IP address’ stuck mean on Android?
It means your phone is asking the router for an IP address through DHCP and the router is not responding or assigning one. Restart the router first, then try forgetting and reconnecting. On Samsung phones, switching from DHCP to a static IP in network settings often breaks the loop.
Conclusion
Start by asking whether other devices in your home can connect, then work through the quick toggles, restarts, and password checks. Most Android phone Wi-Fi not connecting problems clear up within the first few minutes.
If those fail, reset network settings or restart your router. For Samsung or Pixel users, version-specific steps like a DNS change or cache partition wipe can make the difference when nothing else does.
When you have tried every step and your phone still refuses to connect to Wi-Fi anymore, reach out to your ISP or manufacturer with the notes you gathered. You will either solve it yourself or hand off a well-documented problem to someone who can finish the job.
