Switch Error 2110-1118, Wifi error - Nintendo Switch - TronicsFix

I replaced the fan for this switch and the owner said the Switch worked fine before that. Now it gives wifi error. Fan replacement couldn’t have caused this problem, right? Is this error software problem or Wifi/BT IC problem? Everything else works fine. Joy-cons work wirelessly and no shorts or damage around Wifi/BT chip.
