The Bridge worked completely fine when I first set it up, and now I can connect via Bluetooth when at the house but not away through the Wi-Fi, how to solve?

When an Ultraloq Bridge already paired to a lock, while trying to use the App controlling the lock, the lock will only connect the stronger signal either Bluetooth or Wi-Fi. So if you can connect the lock at home, but can't connect it  when you are away, that means the Ultraloq Bridge connection is a failure. Please follow the below steps to do troubleshooting.

Step 1. Turn off and turn on your smartphone.

Step 2. Uninstall the current U-tec App, and install the latest version U-tec App.

Step 3. Sign out and sign in your U-tec Account.

Step 4. Remove and plug in the lock’s batteries to reboot and wait for 2 minutes.

Step 5. Unplug and plug the Bridge and wait for 2 minutes.

Step 6. Check if changed any configuration of your Wi-Fi router.

Step 7. Check if the router's connecting AP device quantity is over its requirement.

Step 8. Confirm the phone's Wi-Fi or carrier's internet is good.

Step 9. If all done, we strongly recommend that reset the Bridge and programming again.
