Join a network
- Open Settings → Wi-FiFlip Wi-Fi on. (The Control Center toggle also works, but only for five minutes unless you tap it there and choose a turn-off duration — Settings is the honest switch.)
- Tap your network's nameKnown networks join silently; new ones ask for a password. Note: iPhone cannot use WPS push-button setup — you always need the password typed. The router sticker usually has it, labelled 'WPA key' or 'Wi-Fi password'.
- Type the password exactlyCase matters. Use the Show-password toggle (the eye) while typing to double-check look-alikes like 0/O and 1/l.
- Confirm, then sanity-checkYou should see 'Connected' under the name. If it shows 'Connected, no internet', the Wi-Fi works but the router's link up the street doesn't — go to that router or your ISP, not back to Settings.
Share the password without typing it
iOS has a built-in, encrypted hand-to-hand pass for saved networks (same family contact rules as AirDrop):
- Both devices signed in with Apple IDs that have each other's contacts listed, with Bluetooth and Wi-Fi on and within a few meters.
- The guest tries to join the network from their Wi-Fi list.
- A 'Join
' card appears on your unlocked iPhone — tap Share Password, face/passcode-confirm, done. Nothing is sent for networks you haven't saved, and you can tap 'Not Now' to skip. - On iOS 16+: you can also view saved passwords directly — Settings → Wi-Fi → the (i) next to your network → tap the hidden password field → Face ID reveals it, ready to type into a TV or laptop.
Per-network settings worth knowing
Settings → Wi-Fi → (i) beside your network:
| Setting | What it does | Recommendation |
|---|---|---|
| Private Wi-Fi Address | Gives this network a random per-network MAC instead of your device's real one | Keep ON for strangers; set to a fixed (Station) address on your home network if router features like access control, reservations, or child profiles need to recognize the device |
| Low Data Mode | Suspends backups and auto-updates on this network | Useful for metered or public links; leave OFF at home |
| Limit IP Address Tracking | Routes traffic for this network through iCloud's private relay | Fine ON at home; some local devices (printers, Chromecasts' discovery) behave better OFF |
| Configure IP | Manual vs DHCP | Leave on DHCP unless you've been told exactly why not |
| Auto-Join | Reconnects to this network when in range | OFF for the neighbor's free-but-sad signal; ON everywhere else |
iPhone cannot choose 2.4 vs 5 GHzThere is no band-preference switch on iOS. If both bands share one name, the iPhone decides (usually well). To force 2.4 GHz onto a stubborn smart-home device, name the bands differently on the router (Home_2.4G) — see the upgrade guide — or temporarily disable 5 GHz while pairing.
Fix the common problems, in order
- Toggle Wi-Fi off and on, then rejoinSettings → Wi-Fi → off/on; if still bad, (i) → Forget This Network → rejoin with the password. This clears a corrupted session more often than any other single move.
- Restart the iPhone and the routerRouter: unplug 10 seconds, replug, wait two minutes for it to re-sync with your ISP. Boring, devastatingly effective.
- Check for a captive portalHotels, cafés, hospitals: joining isn't enough — Safari may need to load the sign-in page. Settings shows 'Sign in to Wi-Fi Network' → tap it.
- Reset network settingsSettings → General → Transfer or Reset iPhone → Reset → Reset Network Settings. Clears all saved Wi-Fi, Bluetooth pairings, and VPN configs — last resort before a support conversation, and it genuinely fixes weird persistent cases.
Extras people actually use
- Wi-Fi Calling: Settings → Apps (Applications) → Phone → Wi-Fi Calling — places regular calls over any internet connection when cells are dead. Also the fix for 'no signal' houses.
- Wi-Fi Assist: Settings → Cellular to the very bottom — silently uses mobile data when Wi-Fi is pitiful. Good for you, potentially not for your cap.
- Ask to Join Networks: toggles whether your iPhone keeps scanning and reminding you about open networks; switch it off to reduce background probing (also a battery and privacy tidy-up).
- Voice access: 'Hey Siri, turn on Wi-Fi' works even from the Lock Screen if you allow it.
Questions people actually ask
Why does my iPhone say 'Connected' but nothing loads?
Usually the router's internet is down (test another device), a stale DHCP lease (forget & rejoin), or a captive portal you haven't agreed to. If only one site/app fails while the rest of the phone works, suspect DNS or Private Relay, not Wi-Fi.
Does turning Bluetooth off help Wi-Fi?
Occasionally, yes — both radios share the 2.4 GHz area of the spectrum, and older iPhones had known Bluetooth-wi-Fi coexistence drag on 2.4 GHz connections. On 5/6 GHz it's irrelevant.
Can I see which Wi-Fi class (generation) I'm connected to?
Not in the interface. If a channel/network is on the router side you're seeing the standard in the status (Wi-Fi 6E etc.); on the phone there's no exposed readout, so trust the router admin page or an analyzer app on another device.
