To debug the actual settings made by the driver, the user should edit the config file <code>/lib/firmware/wlan/qcom_cfg.ini</code> to enbale the log traces, before the insertion of the driver module.
 
 
 
At the start of the file enable the WDA and SME logs:

Regulatory domain[edit | edit source]

A WLAN regulatory domain is a set of laws or policies that control a bounded area.

Currently, there are governing bodies in many countries around the world, like: FCC, IC, RED, Japan (TELEC), Korea (KCC), Brazil (ANATEL), SRRC (China), Australia (RCM)

The main limitations depicted by the regulatory domains affect the available frequencies and the maximum RF power.

Linux setup[edit | edit source]

To setup the regulatory domain under linux systems use the command iw reg set <country code> where <country code> refers to the Country Codes List

DWS WiFi device[edit | edit source]

The embedded FW and the driver SW that support the DWS WiFi device are relesed for good wireless operation for almost all generic WIFI use-cases.
