Wi-Fi, cellular & Bluetooth

Android phone won't connect to Wi-Fi

Usually caused by a saved network issue, a router problem, or an IP conflict rather than a hardware fault. Forgetting the network and restarting the router resolves most cases.

Symptoms

  • Phone shows 'saved, secured' but won't connect
  • Connects then immediately disconnects
  • Other devices work fine on the same Wi-Fi
  • No networks appear in the list at all

Likely causes

  • CommonSaved network profile with outdated passwordA password change on the router leaves the phone trying an old saved credential.
  • CommonRouter needs a restartTemporary router glitches often block new device connections until power cycled.
  • PossibleIP address conflict on the networkTwo devices trying to use the same local IP address can prevent a stable connection.
  • PossibleWi-Fi network band incompatibilitySome older phones can't connect to 5GHz-only networks or newer Wi-Fi 6 configurations.
  • Less commonWi-Fi chip or antenna hardware issueThis would typically affect connecting to any network, not just one.

What to do

  1. Confirm other devices connect fine to the same network to rule out a router-wide problem.
  2. Long-press the network name, select Forget, and rejoin with the correct password.
  3. Restart the router and modem by unplugging for 30 seconds.
  4. Restart the phone to refresh its network connection.
  5. Go to Settings > System > Reset Options > Reset Wi-Fi, Mobile & Bluetooth if the issue continues.
  6. Check the router's admin settings for a 2.4GHz band option if the phone struggles with 5GHz only.
  7. Set a static IP for the phone in its Wi-Fi advanced settings to rule out an IP conflict.
  8. If multiple networks fail and hardware resets don't help, have the Wi-Fi hardware tested by a professional.

When to call a pro

If the phone fails to connect to multiple different Wi-Fi networks after resets, a repair shop can test the Wi-Fi antenna and chip.
