Connect to Wi-Fi and manage saved networks

Most tablets are Wi-Fi only (some cellular models add a SIM), so a stable Wi-Fi connection is essential for downloads, cloud sync, streaming, and app updates.

What you should know

  • Found under Settings > Connections > Wi-Fi (One UI) or Settings > Network & internet > Internet on stock Android.
  • Tap a network name to connect, or tap the gear icon next to a saved network to view its IP address, forget it, or change proxy settings.
  • Advanced options include Wi-Fi frequency band selection and "Switch to mobile data" behavior (on cellular models) when Wi-Fi is weak.
  • A built-in Network diagnostics or "Wi-Fi troubleshooting" tool under Settings > Connections can identify weak signal or IP conflicts.

Why it matters

A dropped or weak Wi-Fi connection interrupts app downloads, cloud backups, and video calls, and can silently prevent scheduled updates or file syncs from ever completing.

Best practices

  • Forget and re-add a network after changing your router's Wi-Fi password to avoid repeated authentication failures.
  • Prefer the 5GHz band when close to the router for faster speeds, and 2.4GHz when farther away for better range.
  • Turn off "Wi-Fi always on during sleep" only if you're troubleshooting battery drain — otherwise leave it on so notifications keep arriving.

Common problems and fixes

Tablet connects to Wi-Fi but shows "No internet"
Forget the network under Settings > Connections > Wi-Fi, restart the router, and reconnect; also check the router isn't blocking the device by MAC address.
Wi-Fi keeps disconnecting when the screen turns off
Check Settings > Connections > Wi-Fi > Advanced > Keep Wi-Fi on during sleep and set it to Always.

Tips and tricks

  • Long-press the Wi-Fi quick-settings tile in the notification shade to jump straight to the network list without opening the full Settings app.

Frequently asked questions

Why does my tablet keep switching to a weaker Wi-Fi network?

Auto-reconnect prioritizes previously saved networks by signal strength and history; forgetting the weaker network stops it from being chosen automatically.
