Hi!,

I have just bought the wifi adapter TL-WN725N for my Raspberry pi 2 (model b) and it worked perfectly (without any type of configuration or driver installation)

wlan0 IEEE 802.11bgn ESSID:"Magic_House" Nickname:""
Mode:Managed Frequency:2.452 GHz Access Point: 90:67:1C:19:70:87
Bit Rate:72.2 Mb/s Sensitivity:0/0
Retry:off RTS thr:off Fragment thr:off
Power Management:off
Link Quality=0/100 Signal level=29/100 Noise level=0/100
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0



However, right now, I am trying to enable the monitor mode :


$> iw dev wlan0 interface add fish0 type monitor flags none
command failed: Operation not permitted (-1)

$>sudo iw dev wlan0 interface add fish0 type monitor flags none
command failed: Invalid argument (-22)

What should I do in order to activate this monitor mode ¿? ¿?



Thank you in advance!,
