Razer DeathAdder V3 Pro Spotty Wired Connection

Swapping to a known-good USB-C data cable can restore the connection. Wiggle-sensitive behavior strongly suggests an internal cable break near the strain relief.

• Try a different USB-C data cable.
• Test multiple USB ports on the computer.
• If wiggling the plug causes disconnects, replace the cable.

Lint or wear on the USB port can prevent a firm connection.

• Inspect the mouse’s USB-C receptacle.
• Gently remove lint with a wooden/plastic pick. Do not bend the port pins.
• If the port feels loose or only holds certain cables, the port may need board-level repair or replacement.
• To replace the USB port, follow our guide here.

Connection issues have been addressed in firmware updates. Some users fix disconnect loops by fully reinstalling the Razer software and updating firmware.

• Update the mouse using the official firmware updater (USB connected).

In Synapse, “Check for Updates.” If problems persist, uninstall all Razer software, reboot, then reinstall Synapse and reapply updates.
