Wi-Fi or app control does not work; device cannot be discovered or paired, but no error code is shown.

Safety first: Network troubleshooting does not require opening the unit; only open if hardware fault is suspected and the unit is unplugged.

Steps to restore Wi-Fi connectivity:

• 1. Check app and network: Ensure the Proscenic app is updated and that your phone is on a 2.4 GHz Wi-Fi network if required by your model.
• 2. Reset Wi-Fi settings: Follow the user manual to reset the air fryer's Wi-Fi (often by holding a specific button combination) and re-enter pairing mode.
• 3. Move router or device: Reduce distance and obstacles between the router and air fryer during setup.
• 4. Firmware update: If possible, update the air fryer firmware via USB or app.
• 5. Inspect Wi-Fi module (advanced): If all else fails, unplug the unit, open the control area, and reseat or replace the Wi-Fi module as described in the Wi-Fi error entry.

Warning: Do not modify internal antennas or RF components; this may violate regulations.
