+   * Preliminary testing shows it is likely that a 6.1 or newer kernel is required & a signed board-2.bin file needs to be placed in the /lib/firmware/ath11k/WCN6855/hw2.1 folder on a running target. This would be using the ath11k open source driver. Silex however recommends using Qualcomm’s LEA driver built using Silex's instructional PDF.             
+   * It is likely hostapd may not work for all bands (NO-IR) could be a factor.

  * If you enable CONFIG_CFG80211_INTERNAL_REGDB and fail to overwrite the default net/wireless/db.txt a default domain will be used which sets the 'no IR' flag on all channels (meaning you can not transmit)
 
+The iw list command will print out frequencies that are supported or may be blocked due to current domain, see example below showing the no IR statement:
+{{{
+Frequencies:
+                * 5955 MHz [1] (20.0 dBm) (no IR)

+Current regulatory domain can be seen with the command and set to US with example below:
