Rivian charger shows E008 and cannot connect to Wi‑Fi; app reports ‘Communication error with charger’

Safety first: Network troubleshooting does not require opening the charger; keep the cover closed and power on.

• Step 1 – Check signal strength: Stand near the charger with a phone and check Wi‑Fi bars. If signal is weak, move the router closer or add a Wi‑Fi extender.
• Step 2 – Verify credentials: In the Rivian app, forget the charger’s network and re-enter the correct SSID and password. Ensure you are using a 2.4 GHz network if the charger does not support 5 GHz.
• Step 3 – Router settings: Ensure MAC filtering is disabled or the charger’s MAC address is allowed. Confirm that your router is not blocking outbound traffic required for Rivian cloud connectivity.
• Step 4 – Power cycle: Reboot both the router and the charger (breaker OFF for 1 minute, then ON).
• Step 5 – Try hotspot test: Temporarily create a mobile hotspot and connect the charger to it via the app. If it works on hotspot but not home Wi‑Fi, the issue is with your network configuration.

If E008 persists on multiple networks, the internal Wi‑Fi module or main control board may be defective and require replacement.
