GM EV home charger’s Wi‑Fi or app connectivity is unreliable; smart features fail, but basic charging still works.

Steps:

• Improve signal: Move your Wi‑Fi router closer to the charger or install a Wi‑Fi extender near the garage.
• Change channel: Log into your router and select a less congested 2.4 GHz channel.
• Re‑pair device: Remove the charger from the GM app and add it again, following the pairing instructions.
• Firmware update: When connectivity is stable, check for and apply any GM firmware updates.

If the charger frequently drops off the network even with strong signal and other devices are stable, the internal Wi‑Fi module or antenna may be defective and require replacement.
