Tablet Loses Date and Time After a Power Cut
anywAiR ducted zone controller troubleshooting
Applicable models: UTY-ANY1 and UTY-ANY2
If the Android tablet resets its date and time after a power interruption, the Wi-Fi connection may fail or the network password may need to be entered again. Adjusting the tablet's automatic time and location settings can improve recovery after power is restored.
1. Typical symptoms
- The tablet displays an incorrect date or time after a power interruption.
- The tablet does not reconnect to Wi-Fi automatically.
- The Wi-Fi password needs to be entered again.
- The anywAiR interface appears offline after power is restored.
Why this occurs: The tablet includes a battery backup that should retain most settings. However, an incorrect system date or time can prevent secure Wi-Fi and internet services from reconnecting correctly.
2. Tablet settings procedure
| 1 | Open the Android tablet settings. From the tablet home screen, open the system Settings menu. |
| 2 | Open the date and time settings. Locate the tablet's Date & time menu. |
| 3 | Turn on “Use network time”. This allows the tablet to update its date and time automatically from the internet after power and Wi-Fi are restored. |
| 4 | Open the location settings. Return to the main Settings menu and locate the tablet's location options. |
| 5 | Turn off “Default location”. This can reduce connection dropouts and improve Wi-Fi stability following a power interruption. |
| 6 | Restart the tablet and confirm operation. Check that the correct date and time are displayed and confirm that the tablet reconnects to Wi-Fi without requiring the password to be entered again. |
3. Expected result
After these settings are changed, the tablet should automatically retrieve the correct date and time when internet access returns. This should reduce Wi-Fi connection failures and the need to manually re-enter network credentials after a power cut.
If the issue continues: Confirm that the tablet is connecting to a Wi-Fi network with internet access. Also confirm that the tablet's internal backup battery is operating correctly. Further diagnosis may be required if the date and time reset after every brief power interruption.
