Join a network
- Settings → Network & internet → InternetSamsung: Settings → Connections → Wi-Fi. The quick-settings panel (swipe down) also long-presses straight into the same screen.
- Tap the network, enter the password, ConnectCheck 'Show password'; case and 0/O mistakes are the #1 failed join. Pixel and recent Android show saved passwords behind your lock (Settings → Internet → saved network → tap the password), so a TV can be typed into without guesswork.
- Decide the extrasOn the join sheet Android asks whether to auto-connect and whether to skip notification of poor-quality/open networks — defaults are sane.
- WPS where you're lazy in bulkUnlike iOS, Android can still push-button pair: Internet → Add network → WPS Push Button (Samsung: Connections → WPS). Works on routers with a physical button; no password needed.
Share Wi-Fi with a QR code
Android's killer convenience feature. On your connected phone: Settings → Internet (Samsung: Connections → Wi-Fi) → tap the gear next to your network → Scan / Share QR code → authenticate → show. The joining phone opens its camera, hits the QR, and connects — no typing, password never displayed in words. Google's Quick Share/Sharesheet path also lets you 'Share password' phone-to-phone with nearby Android devices (Android 12+). The QR encodes the network name and key as plain text in the code: share it like you'd share the password itself.
Per-network: the (gear) menu on the connected network
| Setting | What it does | Recommendation |
|---|---|---|
| Privacy / MAC type | Randomized MAC by default per network (Pixel: 'Privacy' under Advanced); Samsung has per-network randomized/device MAC too | Randomized for the café; switch to Device MAC at home if you use router access rules, reservations or parental profiles |
| Auto-connect / Connect to this network | Whether Android re-joins in range | Off for the neighbor's free network |
| Metered | Treats network as data-capped, pauses auto-updates and backups | For hotspots and some hotels |
| Private DNS | Encrypted DNS (hostname) for this device | Optional: set 'dns.quad9.net' for malware-blocking, or leave off — see Security guide |
| Advanced → Static IP | Manual addressing under DHCP | Rarely the fix; printer/console ports are the usual reason |
The adaptive features that bite
Android's helpful automations can cause real problems:
- Adaptive Wi-Fi / 'Auto-switch to mobile data' (Pixel: Internet → Wi-Fi → Network preferences → 'Switch to mobile data'; Samsung: Intelligent Wi-Fi → 'Switch to mobile data'): when Wi-Fi seems 'poor', it silently drains your mobile plan. Great on flights, bad with a 5 GB cap or in low-signal apartments with a working line. Turn it off if mobile data is mysteriously evaporating.
- Intelligent Wi-Fi (Samsung) hides a pile: scan always available, auto-reconnect to open networks, network optimizer. The one that surprises people is turning Wi-Fi scanning on for better location even with Wi-Fi off — switch off with the master toggle if privacy matters.
- Multi-network / Dual Wi-Fi (some Xiaomi/Oppo/Samsung models): stays connected to 2.4 GHz + 5 GHz at once and can use mobile data simultaneously — battery cost if enabled by default.
- Wi-Fi Direct shares files and prints over ad-hoc wireless; leave it off outside transfers to keep the radio private.
Choose the right band
Stock Pixel has no band preference; force it on the router side (separate SSIDs, or 2.4 only while pairing a smart bulb). Many Android skins (Xiaomi, Huawei older EMUI, some Samsung firmwares) have a 'Prefer 5GHz'/'Smart network priority' switch that, paradoxically, can cause devices to refuse a weak-but-usable 5 GHz and stay on 2.4 — if 'faster Wi-Fi at home feels weird on my phone', try this toggle either way.
Fix the common problems, in order
- Quick-settings toggle off; wait 10 s; onThen forget & rejoin (gear → Forget) if it reconnects badly.
- Restart the phone and the routerYes, same as every guide on this site; on Android leave the phone on the charger while the router reboots so a stuck DHCP renewal doesn't add noise.
- Check for a captive portalNotification: 'Sign in to Wi-Fi network.' If the page doesn't load, temporarily disable Private DNS — a known captive-portal breaker.
- Reset network settingsSettings → System → Reset options → Reset Wi-Fi, mobile & Bluetooth. Clears saved networks and pairings, not your photos. Android's big red button.
Questions people actually ask
Where did 'Wi-Fi sleep policy' go?
Older Androids could keep Wi-Fi alive during sleep; modern versions handle it automatically via the OS power system. If Wi-Fi drops when the phone sleeps, that's now almost always router-side (DHCP lease length, aggressive power-save on your router's radios) — see Troubleshooting.
Why does my phone show 5 GHz and refuse 2.4-only devices?
The smart-home pairing dance: many IoT setup flows run their own temporary hotspot from the phone; a phone connected to 5 GHz may fail to join the device's 2.4 GHz-only hotspot. Temporarily pick the 2.4 GHz network, or move pairing near the router.
Does Android 13+ change anything?
Incremental: per-network MAC randomized by default everywhere, ephemeral QR-code sharing UIs, and smarter auto-join prompts that ask before joining open networks.
