Troubleshooting CAROL Bike 1.0 Wi‑Fi & Internet Connection

CAROL Bike 1.0 requires a 2.4 GHz Wi‑Fi connection and works with WPA/WPA2 PSK security. The guide below shows how to manually connect, clear saved networks, and alternative methods if the bike still will not access the internet.

CAROL Bike 1st generation is compatible with the 2.4 GHz Wi‑Fi band only. Routers that use both 2.4 GHz and 5 GHz (dual‑band) can change how devices connect; fluctuations or band selection can prevent the bike from establishing a stable internet connection.
Recent router updates or changes to the router configuration can also cause connectivity issues.

From the bike login screen, tap the sprocket (settings) icon in the top‑right corner.
Tap "Connect Wi‑Fi."
Open "Saved Networks":
- Scroll down and tap "Saved Networks."
- Select each saved network and tap "Forget."
- Return to the Wi‑Fi Networks list.
Add your home network:
- Scroll down and tap "Add network."
- Enter your Network Name (case‑sensitive).
- Set Security to "WPA/WPA2 PSK."
- Enter your Wi‑Fi password.
- Tap "Save" on the on‑screen keyboard (top‑right).
If the network does not connect immediately:
- Toggle WLAN off (top‑right) then toggle it back on. The bike should then connect.

Force use of the 2.4 GHz band:
- Configure your router so the bike connects specifically to the 2.4 GHz band (for example by splitting SSIDs for 2.4 GHz and 5 GHz).
Use a Wi‑Fi extender:
- Configure a Wi‑Fi extender as a dedicated access point for the CAROL Bike and ensure the extender uses WPA2/PSK encryption.
Create a guest network:
- Set up a guest network on the router using WPA2/PSK and connect the bike to that network.
Connect the bike to a mobile hotspot:
- Create a hotspot on a phone and connect the bike to that network.
- For iOS hotspot sharing, enable the device setting that maximizes compatibility (Maximise Compatibility) before connecting.

Confirm the router broadcasts a 2.4 GHz network (or split SSIDs so 2.4 GHz is selectable).
Forget any previously saved networks on the bike before re‑adding the correct network credentials.
Enter the Wi‑Fi network name exactly (case‑sensitive) and the correct password.
Toggle WLAN off/on on the bike if it does not connect after saving network details.
Try an alternate network (extender, guest network, or mobile hotspot) if the primary network remains inaccessible.
Ensure the chosen network uses WPA/WPA2 PSK encryption.

This article explains common causes and step‑by‑step troubleshooting for connecting a CAROL Bike 1.0 to Wi‑Fi and the internet, and provides alternative connection options when the bike cannot join a home network.
