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- CommonSaved network profile with outdated passwordA password change on the router leaves the phone trying an old saved credential.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
- Confirm other devices connect fine to the same network to rule out a router-wide problem.
- Long-press the network name, select Forget, and rejoin with the correct password.
- Restart the router and modem by unplugging for 30 seconds.
- Restart the phone to refresh its network connection.
- Go to Settings > System > Reset Options > Reset Wi-Fi, Mobile & Bluetooth if the issue continues.
- Check the router's admin settings for a 2.4GHz band option if the phone struggles with 5GHz only.
- Set a static IP for the phone in its Wi-Fi advanced settings to rule out an IP conflict.
- 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.
