Is possible change the 0.xxx watt power?

Hi i have put a copper plate as passive cooling on the soc, is possibile to elevate the 0.xxx watt power?
I need stronger signal capacity.

@MR0000001 the driver can’t provide a “watt slider” that overrides RF/regulatory limits.

What you can do (and what you cannot):

• You cannot legally force transmit power above your country’s regulatory domain limits from a driver setting.
• The dBm values you may see reported are not a direct “watts” control; effective range depends heavily on regulatory domain, adapter firmware/EEPROM calibration, antenna quality/placement, USB signal integrity, and the AP/channel environment.

Changes in PR #3 / commit b1866ce2b857a8dfe2e147e19eb8eca0a842ce18 add explicit guidance to the README so expectations are clear:

• Commit: b1866ce
• Docs:

  Lines 321 to 327 in b1866ce

  	- Driver/module settings cannot legally override country regulatory limits.
  	- Reported dBm values are not a direct “watt slider”; adapter firmware, regulatory domain, and AP environment all affect effective range.
  	- For range improvements, prioritize antenna placement, USB 3.0 signal quality, and channel planning before changing power-related options.

If you want help improving signal/range on your setup, please retest on the latest available versions (OS packages + kernel + this driver), then share:

• cat /etc/os-release
• uname -a
• Whether this is a SBC (you mentioned “SoC”), and what model it is
• Adapter model, USB port type (USB2 vs USB3), and whether you use any hub/dock/extension cable
