Frequently Asked Questions

Common Issues

This adapter currently uses the native driver from macOS which does not support manually setting its speed to 2.5Gbps or 5Gbps. The highest speed available will be automatically negotiated by the adapter. If you wish to Manually Set it to a 2.5Gbps or 5Gbps, we recommend setting the speed from the Upstream Network Connection.
