A ChargePoint Home Flex that won't connect to WiFi usually has one of four problems. The phone can't reach the charger over Bluetooth during setup, the WiFi signal at the garage wall is too weak, the router's settings confuse the charger, or the network name or password changed after setup. The good news is that every fix on this list happens on your phone or router. None of it involves the charger's wiring. Work through the steps in order, and the charger will usually connect within a few minutes.

First, does WiFi actually matter right now?

ChargePoint's own troubleshooting page says that if your WiFi goes down, the Home Flex will still charge your car on schedule. So if the car is charging, you have time to fix WiFi calmly. WiFi is needed for activation, app control, remote start, charging history and over-the-air firmware updates. The datasheet says the charger stores up to 90 days (100 sessions) of charging data locally, so an outage doesn't wipe your history.

If the car isn't charging at all and the charger shows a red fault light, that's a different problem. Fix the fault first, because WiFi won't help with it.

What the Home Flex supports

ChargePoint's Home Flex datasheet lists 2.4 and 5 GHz WiFi (802.11 a/b/g/n). That's older WiFi standards only, so the charger doesn't use WiFi 6 features. In practice, owners in forums report better results on 2.4 GHz. It reaches further through garage walls, and many mesh systems steer devices between bands in ways older chips handle badly.

Fix 1: Get Bluetooth right during activation

Your phone talks to the charger over Bluetooth to hand over the WiFi details. ChargePoint says that if you see "Unable to connect to home charger" or "Can't find home charger," you should check that Bluetooth is on and stand within a few feet of the station.

1. Turn on Bluetooth and WiFi on your phone, and connect the phone to the same home network you want the charger on.
2. Stand next to the charger, not in the house.
3. Open the ChargePoint app, go to Home Charger, choose Set Up Home Charger, then Activate, and follow the prompts.
4. If it fails, force-close the app, toggle Bluetooth off and on, and try again.

Fix 2: Check the signal at the charger

ChargePoint says activation and connected features need WiFi at the spot where the station is installed. Stand at the charger with your phone on WiFi only, then load a web page or run a speed test. If it's slow, stalls or drops, the charger will struggle too, and its antenna sits inside a metal-and-plastic case on a wall that may be concrete.

Ways to improve the signal, from cheapest:

• Move the router or a mesh node closer to the garage, or higher up.
• Add a WiFi extender on an outlet between the router and the garage.
• Run Ethernet to the garage and add an access point there. The charger itself connects over WiFi, so the access point does the work.

ChargePoint notes that it tested its home chargers with certain 802.11b/g-capable extenders, and that AMPED Wireless extenders do not work with Home. Choose a different extender brand.

Fix 3: Simplify the router settings

This is where most stubborn cases end. Settings that work fine for phones and laptops can stop a charger from joining. Try these on your router or mesh app, one at a time:

• Split the bands. If 2.4 and 5 GHz share one network name, create a separate 2.4 GHz network name, or use a guest network that's 2.4 GHz only.
• Use WPA2. Set security to WPA2-PSK (AES). WPA3-only or mixed WPA2/WPA3 modes can cause failures on older WiFi chips.
• Avoid captive portals. Networks with a sign-in web page, like some ISP hotspots and apartment WiFi, won't work for the charger.
• Keep the password simple. Some owners report trouble with unusual special characters. Letters and numbers are safest.
• Check device limits and filters. MAC filtering or a full device list can block a new device.

One workaround reported on Reddit's r/chargepoint in October 2025 is worth knowing. The owner's app listed their secured WPA2 networks as if they were open, with no padlock, and never asked for a password. They fixed it by creating a WPA2 guest network, hiding its name (turning off SSID broadcast), then choosing "Other" in the app and typing the network name and password manually. That's one owner's report, not official advice, but it's easy to undo.

Fix 4: Restart in the right order

ChargePoint's checklist starts with your internet itself. Make sure another device can browse on the same WiFi. Then restart the router by unplugging it for a few seconds, and check its cables to the modem. If the charger was online before and dropped off, a router restart fixes it more often than anything else.

If you also want to restart the charger, use only its dedicated breaker. Switch it off, wait about a minute, and switch it back on. Don't remove the charger's cover or unplug wiring.

Fix 5: Use Reconfigure WiFi after any network change

If you changed the network name, password, router or internet provider, the charger is still trying the old details. ChargePoint says to open the app's home charger settings and choose Reconfigure WiFi. Stand by the charger with Bluetooth on while you do this.

Products that can help

These extenders both broadcast 2.4 GHz, the band chargers handle most reliably. Specs are from the Amazon listings, and we haven't tested them with a Home Flex. Extenders improve coverage, not speed, and a charger needs very little bandwidth.

Specs are from manufacturer and retailer listings and can change between versions; check the listing before you buy. We don't show prices because they change often; the button shows the current price on Amazon.

The RE500X has an access point mode with a gigabit Ethernet port. If you can run a network cable to the garage, it can create a strong WiFi signal right next to the charger. Both units are for indoor use, so plug them in inside the house or a dry garage, not outdoors.

Still offline? Call ChargePoint

If none of this works, ChargePoint lists its US home charger support number as 1-888-758-4389. Tell them the steps you tried, your router model, and whether the app ever saw the charger over Bluetooth. That helps them tell an app problem from a radio fault in the charger.

Running a different brand? The same signal and router fixes apply to most smart chargers, including the Grizzl-E Connect. If your Grizzl-E shows red flashes instead, see our Grizzl-E red light code guide. For Wallbox, see our Pulsar Plus red light guide.

FAQ

Will my ChargePoint Home Flex charge without WiFi?

Yes. ChargePoint says the charger still charges on schedule if WiFi goes down. You lose app control, remote features and live history until it reconnects.

Does the ChargePoint Home Flex work on 5 GHz WiFi?

The datasheet lists 2.4 and 5 GHz support. Owners generally report that 2.4 GHz is more reliable in garages because it travels further through walls.

Why can't the app find my charger?

The app uses Bluetooth for setup. Turn on Bluetooth, stand within a few feet of the charger, and restart the app. If it still can't find it, switch the charger's breaker off and on, then try again.

How do I connect my Home Flex to a new router?

In the ChargePoint app, open your home charger settings and choose Reconfigure WiFi, then enter the new network name and password while standing by the charger.

Which WiFi extenders work with ChargePoint Home?

ChargePoint says it tested certain 802.11b/g extenders and that AMPED Wireless extenders do not work with Home. Any extender that broadcasts a 2.4 GHz WPA2 network at the charger is a good starting point.
