Phone or Tablet Won't Connect to Wi-Fi
iPhone, iPad, or Android phone/tablet — the cause is almost always one of a few common culprits. Work through these before assuming it's your router.
Quick answer
Forget the network in your Wi-Fi settings, restart the phone, then rejoin and re-enter the password. That clears out most corrupted connection profiles on its own.
Steps to fix it
- Toggle Wi-Fi off and back onSounds too simple, but it resets the radio connection and clears a surprising number of one-off glitches. iPhone or iPad: swipe down from the top-right corner to open Control Center, tap the Wi-Fi icon to turn it off, wait about 10 seconds, then tap it again (or go to Settings > Wi-Fi and use the toggle at the top). Android: swipe down from the top of the screen to open Quick Settings, tap the Wi-Fi icon to turn it off, wait about 10 seconds, then tap it again (or go to Settings > Network & Internet > Wi-Fi and use the toggle at the top).
- Forget the network, then rejoin itiPhone/iPad: Settings > Wi-Fi > tap the (i) next to the network > Forget This Network. Android: Settings > Network & internet > Internet > tap the gear next to the network > Forget. Then reconnect and re-enter the password fresh.
- Restart the deviceA full restart clears out background processes that can quietly interfere with the Wi-Fi radio.
- Turn Airplane Mode on, wait 10 seconds, then offiPhone/iPad: swipe down from the top-right corner to open Control Center, tap the airplane icon, wait 10 seconds, then tap it again (or Settings > Airplane Mode, toggle on then off). Android: swipe down from the top of the screen (twice, on some phones) to open Quick Settings, tap the airplane icon, wait 10 seconds, then tap it again. This forces every radio on the device — Wi-Fi included — to fully reset.
- Check whether the phone is switching away from Wi-Fi on purposeSometimes it isn't actually disconnecting — the phone is deliberately switching to cellular data because it thinks Wi-Fi is too weak, which looks identical to a real disconnect. iPhone: Settings > Cellular, scroll down and turn off Wi-Fi Assist — this feature automatically shifts to cellular whenever Wi-Fi seems slow, even if you'd rather it stayed on Wi-Fi. Android: Settings > Network & Internet > Wi-Fi > Wi-Fi preferences, and turn off "Switch to mobile data automatically" or "Avoid poor connections" (exact wording varies by brand). If turning this off stops the drops, the phone was never really losing Wi-Fi — it was choosing to leave it.
- Check if it's only disconnecting when the screen is off or the device is idle — a genuinely common, separate issueThis is different from the Wi-Fi Assist issue above: here, the device is fully cutting power to the Wi-Fi radio itself to save battery whenever it's locked or sitting idle, then reconnecting slowly once you pick it up. iPhone/iPad: this is usually Low Power Mode being on — Settings > Battery, and turn off Low Power Mode (it aggressively throttles wireless radios below 20% battery, or whenever you've turned it on manually — this applies to iPad the same way it does iPhone). Android: this is almost always battery optimization or a "Wi-Fi sleep policy" restricting background network use — go to Settings > Battery (or Apps > [browser/messaging apps] > Battery), look for Battery Optimization or Adaptive Battery, and either turn it off for key apps or look for a separate "Keep Wi-Fi on during sleep" setting and set it to Always (exact wording and location varies significantly by phone brand — Samsung, Pixel, and others each place this slightly differently). If the phone reconnects fine while you're actively using it but drops a few minutes after the screen turns off, this is almost certainly the cause.
- Check the date and time are set correctlyiPhone/iPad: Settings > General > Date & Time > enable Set Automatically. Android: Settings > System > Date & time > enable Automatic date & time. An incorrect date can cause the device to reject your router's security certificate, especially on networks using WPA3 (the newer, stricter version of the security standard that protects your Wi-Fi password — most routers made in the last few years default to it).
- Update the device's operating systemiPhone/iPad: Settings > General > Software Update. Android: Settings > System > System update (or Software update, depending on brand). Wi-Fi driver bugs get patched regularly — an outdated OS is a common, overlooked cause.
- Check your router isn't blocking the device by MAC addressA MAC address is a unique ID number built into every device's Wi-Fi hardware — think of it like a serial number your router can use to recognize (or block) a specific device. Most people never touch this, so you can likely skip this step unless you know you've set up device filtering before. If you have: find the MAC address under Android: Settings > About > Status. iPhone/iPad: Settings > General > About, under Wi-Fi Address. Then log into your router's admin page (usually by typing 192.168.1.1 or 192.168.0.1 into a browser, or via its app) and look for a section called MAC Filtering, Device Filtering, or Access Control — confirm the address is listed as allowed, not blocked. One iPhone/iPad-specific wrinkle: modern Apple devices use a randomized "Private Wi-Fi Address" by default for each network, which can rotate over time — if your router's filter was set up using an old address, it may no longer match. You can check or turn this off for your home network under Settings > Wi-Fi, tap the (i) next to your network, and look for Private Wi-Fi Address.
- Reset network settings entirelyiPhone/iPad: Settings > General > Transfer or Reset [device name] > Reset > Reset Network Settings (you'll need your passcode) — the menu says "Transfer or Reset iPhone" or "Transfer or Reset iPad" depending on which device you're on. Android: Settings > System > Reset options > Reset Wi-Fi, mobile & Bluetooth (on Samsung: Settings > General management > Reset > Reset network settings). This clears every saved Wi-Fi profile, VPN, and Bluetooth pairing — a strong last resort.
- Rule out a router that's past its prime — or a phone with failing Wi-Fi hardwareIf every other device on your network also struggles, and your router is several years old, the router itself — not your phone — may be the actual bottleneck worth replacing. But if it's only this one phone or tablet, and none of the steps above help, the device's Wi-Fi antenna can fail with age or after a drop — especially on older phones. At that point, replacing the device is usually more realistic than continued troubleshooting.
Common questions
Why does my phone connect but show no internet access?
This usually means the device joined the Wi-Fi network but can't reach the internet through it — often a captive portal login it hasn't completed (the login or "I agree" page some Wi-Fi networks show in a browser before letting you online — common at hotels, airports, and coffee shops, and easy to miss if it doesn't pop up automatically), or a DNS problem. DNS is what translates website names like google.com into the numbers your phone actually uses to reach them; when it breaks, Wi-Fi connects but nothing loads. If only your phone or tablet has the issue, try changing its DNS directly: iPhone/iPad: go to Settings > Wi-Fi, tap the (i) circle next to your network, tap Configure DNS, switch to Manual, remove any existing entries, and add 8.8.8.8. Android: go to Settings > Network & Internet > Wi-Fi, tap the gear icon next to your network, tap Advanced or Edit, set IP settings to Static, and enter 8.8.8.8 in the DNS 1 field. If every device has the same issue, restart the router first — that fixes it most of the time — and if not, the same DNS change can be made on the router itself under its Internet or WAN settings (log into its admin page, usually 192.168.1.1 or 192.168.0.1 in a browser).
Why does Wi-Fi work on one device but not another on the same network?
That points to something specific to the struggling device — a saved network profile, outdated software, or a driver issue — rather than the router itself, since other devices are working fine. Start with the steps at the top of this page for the affected device: forget and rejoin the network, restart the device, and check for a pending software update. If it still won't connect while everything else does, check whether the device is old enough that it may only support 2.4GHz. The simplest way to check: go into the device's Wi-Fi settings — iPhone or iPad: open Settings and tap Wi-Fi near the top; Android: open Settings and tap Network & Internet, then Wi-Fi (on some phones it's just Settings > Wi-Fi directly) — and see whether it can even see a 5GHz network name in the list of available networks (5GHz names often end in "-5G"). If it only ever shows the 2.4GHz network regardless of signal strength, that's a strong sign it doesn't support 5GHz, and you should make sure it's connected to the 2.4GHz network specifically rather than trying to join the 5GHz one.
Does restarting the router help with phone connection issues?
Sometimes, especially if every device on the network is having trouble. But if it's only your phone or tablet, the fix is almost always on the device side.
