[SOLVED] Razer Deathadder V2 Pro Bluetooth Not Working

Deathadder V2 Pro is a wireless mouse that can operate with either Hyperspeed or Bluetooth connectivity.

Hyperspeed requires the USB dongle provided with the mouse. However if you don’t have a spare USB port available then you have to use Bluetooth.

Many users have encountered issues with Bluetooth. These issues could range from an inability to connect to a flaky or intermittent connection.

In this post we have provided solutions to these problems. Without further ado, let’s get into it.

Mode selector

As mentioned earlier, Deathadder v2 Pro uses two different methods of wireless connectivity:

  • Hyperspeed
  • Bluetooth

The mouse uses only one of the two methods at any given time.

To enable Bluetooth connectivity, make sure that you’ve selected BT under the mouse using the slider switch.

Select BT mode

If it’s set to either 2.4 or OFF, it won’t be able to pair with Bluetooth.

Bluetooth Pairing

If you’ve removed the mouse from your Bluetooth devices on your PC, the mouse could still be in a mode where it ‘thinks’ it’s still connected. If this is the case it won’t broadcast messages.

Press and hold both side buttons and dpi-up button at the same time for three seconds to put the device in pairing mode. The logo should blink twice in repeated intervals to indicate that it is in pairing mode.

Your PC should now be able to see the mouse again for re-pairing when you search for it.

Bluetooth Connect

When the mouse has paired, the Razer logo will briefly turn solid blue before displaying its lighting effect.

Bluetooth connectivity is limited to 30 feet. However in practice, depending on other wireless devices nearby, the range can be limited to less than that. To ensure better signal quality, move the mouse closer to your PC.

If you encounter issues with Bluetooth pairing, try pairing with another Bluetooth device such as an external speaker. If it doesn’t work then there’s likely an issue with Bluetooth on your PC.

Try Another Computer

To rule out Bluetooth issues with your PC try pairing the mouse with another PC or Mac. If it works, then it’s most likely an issue with your PC.

Some common things to check for:

  • Did you update Windows recently? If so, you might have to roll back the update to see if that caused the issue
  • Are the Bluetooth drivers updated?
  • Although unlikely, it could also be a failure of the Bluetooth chip in your PC.

Deathadder V2 Pro Keeps Disconnecting

One common reason for this is interference due to other wireless devices (Wi-Fi routers, phones or microwave ovens) operating nearby. The other major cause of interference is USB 3.0 devices which are very noisy from a Radio perspective. This results in more interference (especially when they are in heavy use) which in turn disrupts the Bluetooth communication link.

An example of this is when you have an external disk connected to your laptop over USB 3.

Pause the use of the USB 3 device and see if it improves the quality of your Bluetooth connection. As well, move wireless routers, phones and other wireless devices away from your mouse.

If the connection is more stable, then the problem was definitely due to interference. The only way to solve this permanently is to be mindful of other wireless devices nearby.

Final suggestions

If you have tried all the suggestions in our post and none of them worked, it might be worthwhile to contact support at Razer. If your mouse is still under warranty you can ask to RMA it.
