Hi @trongbang108 ,

Do you see the wlan0 interface when you run command "ifconfig"?

Can you try running "ifconfig wlan0 up"?

[trongbang108]

thank you for your response, I changed to another wl version

pi@raspberrypi:~/wlfmac $ iwconfig
lo no wireless extensions.
eth0 no wireless extensions.

wlan0 IEEE 802.11 Mode:Master Tx-Power=19 dBm

@raks_99  Hi experter, I'm still watting for your respone. Thank you

[raks_99]

Hi @trongbang108 ,

You need to use manufacturing test firmware to run the pkteng command.

I cannot share the firmware in the community so you can create a case in mycases to request the testing firmware.

Thanks

hi @raks_99 

How to create a case to get testing firmware, thanks

[raks_99 · Accepted solution]

Hi @trongbang108 ,

You can request MFG firmware from the module maker (I think it is Muarata in the case of RPI module) or you can create a case here :

Thanks
