Dead Wifi Ender3 V3

Ender-3 V3 Printers Creality Ender-3 V3 (Regular)

Hi All,

I have an Ender 3 V3 regular rooted with Guppy. Mid-print, it suddenly lost connection to Mainsail. Since then, it seems like the Wi-Fi on the machine is broken. When I try searching for Wi-Fi, it just shows a loading circle. The Wi-Fi address on the device shows 0.0.0.0.

Troubleshooting steps performed:

  1. Rebooting the machine
  2. Rebooting the router
  3. Checked the router page to see if the MAC address is present (not present)
  4. Connecting via hotspot from a mobile phone
  5. Left the printer unpowered overnight
  6. Visually checked the mainboard for any physical damage
  7. Checked Wi-Fi antenna plug

The printer performs all its functions as normal. It just won’t connect to Wi-Fi. I can’t reflash the firmware, as I can’t SSH into it. Is there a way to reflash the mainboard as I see a micro USB internally?

Any help would be much appreciated.

Regards, Jason

I added ‘factory_reset’ to a pendrive and booted the machine which restored it back to the creality screen. I then had the ability to ‘Reset to defaults’ from the screen menu. which resolved the issue.
