FAQ: ALFA PowerControl Driver
Does the driver work on Windows 10 or 11?
The PowerControl driver was originally written for older Windows versions. However, it can often be installed on newer systems by using Windows Compatibility Mode (e.g., Windows 7 compatibility).
Can I set the power to maximum legally?
This depends on your country. In the EU, for instance, the maximum transmission power (EIRP) for 2.4 GHz is strictly limited to 20 dBm (100 mW). Maximum power should only be used in shielded laboratory environments.
