Problem

The Corsair Harpoon may fail to pair over Bluetooth, or it may not appear in your device’s list of available connections. This usually happens if the mouse isn’t in pairing mode, the battery is low, or the PC/tablet’s Bluetooth settings are misconfigured.

Solution

You can fix Corsair Harpoon Bluetooth pairing issues by re-entering pairing mode, resetting the connection, and ensuring your device’s Bluetooth is working properly.

Step-by-step instructions

Check the basics

Make sure the mouse is charged or connected via USB cable for power.
On the bottom of the mouse, set the switch to Bluetooth mode.
Hold the Bluetooth pairing button until the LED flashes, indicating pairing mode.

On Windows PC
4. Go to Settings > Devices > Bluetooth & other devices.
5. Ensure Bluetooth is turned on.
6. Select Add Bluetooth or other device > Bluetooth.
7. Choose Corsair Harpoon Wireless from the list.
8. Wait for confirmation, then test mouse movement and clicks.

On macOS
9. Open System Settings > Bluetooth.
10. Turn Bluetooth on if it isn’t already.
11. Select Corsair Harpoon Wireless when it appears and click Connect.

If the mouse won’t pair
12. Remove any old or failed pairings for the Harpoon from your device’s Bluetooth list.
13. Restart both the mouse and your PC or Mac.
14. Try pairing again in Bluetooth mode.

Update firmware and drivers
15. Connect the mouse via USB and open Corsair iCUE software.
16. Update the mouse firmware if available.
17. Ensure your device’s Bluetooth drivers and operating system are up to date.

Optional methods or tools

Wired USB mode: Use this if Bluetooth continues to fail.
2.4GHz dongle: Provides more stable wireless performance compared to Bluetooth.

Best practices or tips

Keep the mouse within a meter of your PC or device when pairing.
Avoid pairing the Harpoon with too many devices at once, as this can cause confusion.
Use Bluetooth only for convenience (e.g., laptops and tablets); for gaming, use the 2.4GHz dongle for lower latency.
If problems persist, reset your Bluetooth settings and retry the pairing process.
