Razer Basilisk Ultimate dongle keeps disconnecting

My Razer Basilisk Ultimate wireless dongle repeatedly disconnects, making the mouse unusable in wireless mode.

I have already tried:

  • Updating all Razer software and firmware

  • Using multiple USB ports

  • Testing different configurations

  • Using the mouse in wired mode (works correctly)

The issue appears to be isolated to the wireless dongle. The mouse itself functions normally. Since replacement dongles do not seem to be sold separately, I would like to know if there are any repair, replacement, or alternative solutions available, as I would prefer not to replace the entire mouse.

Hi Dim_game,

I'm here to help. I understand that you're experiencing wireless connection issues with your Razer Basilisk Ultimate. To isolate the problem, please ensure that the USB dongle is connected directly to your PC and that there is a clear line of sight between the mouse and the dongle. Also, try downloading the pairing utility and running it on your computer. 

If the problem persists, please send me a  PM with your device's serial number and proof of purchase for warranty validation. Thank you!
