Issues with wlan0 interface

[mauriciospinelli]

Hi all,

I recently bought a WLAN Pi M4 and I'm facing issues with the wlan0 driver. I'm currently discovering WLAN Pi capabilities and features so I might be missing something.

My wlan0 doesn't come up at all, I have tried different things but I'm running out of ideas

I have my wlan0 configured under /etc/network/interfaces

# wlan0 configuration
allow-hotplug wlan0
iface wlan0 inet dhcp
wireless-power off
wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

Also the config under wpa_supplicant.conf

network={
  ssid="WIFIXYZ"
  key_mgmt=WPA-EAP
  eap=PEAP
  anonymous_identity="anonymous"
  identity="XYZ"
  password="XYZ"
  phase2="autheap=MSCHAPV2"
  priority=2
}

some info was changed on the above output for privacy reasons

when I try to bring the interface up I have different issues

wlanpi@wpAMOF01:/etc/network $ sudo  ifup wlan0

Can someone help me out?

thank you
