Tesla Wall Connector: Four red blinks, repeating
The internet connection was lost; online features are disabled. Charging itself is not named as stopped.
Applies to: Gen 3 Wall Connector, J1772 version. What you see: red, flashing or blinking, 4 blinks, then a pause.
What Tesla says to do
- Tesla says: check for objects that could interfere with the Wi-Fi signal where the Wall Connector is.
- Tesla says: confirm that your Wi-Fi router is working.
- Tesla says: if the Wi-Fi password changed recently, follow the commissioning process on your phone to update the Wi-Fi settings.
The maker puts this light down to Wi-Fi or the internet. If the problem is the router itself, its own lights are explained on the router and broadband hub lights page.
Connector: these lights are from Tesla’s manual for the J1772 (Type 1) version. What that connector’s label means is on its own page.
