#=========================== Radio parameters - End ==========================

the one i use is different in one way :

FEM1_TXBiPReferencePDvoltage_2_4G = 375 # Unit: 1mV, Format: Unsigned, Source: TI
FEM1_TxBiPReferencePower_2_4G = 128 # Unit: 1/8dB, Format: Signed, Source: TI

so i changed :

FEM1_TXBiPReferencePDvoltage_2_4G = 0177 # Unit: 1mV, Format: Unsigned, Source: TI

FEM1_TxBiPReferencePower_2_4G = 80 # Unit: 1/8dB, Format: Signed, Source: TI​

to

FEM1_TXBiPReferencePDvoltage_2_4G = 375 # Unit: 1mV, Format: Unsigned, Source: TI

FEM1_TxBiPReferencePower_2_4G = 128 # Unit: 1/8dB, Format: Signed, Source: TI​

(this second code is the one there use to be in older tiwlan.ini, used before

The idea is that you try both and see if you experience any changes in wifi behavior ...
