airodump-ng unable to capture packets

I'm trying to capture Wi-Fi (802.11) packets on a 2.4Ghz network with a BeaglePlay board using airodump-ng. I have mostly followed this instruction. The interface was set to monitor mode and was verified with iwconfig . debian@BeagleBone:~$ iwconfig wlan0mon wlan0mon IEEE 802.11 Mode:Monitor Frequency:2.462 GHz Retry short limit:7 RTS thr:off Fragment thr:off Power Management:off I then run sudo airodump-ng wlan0mon , but it doesn't capture any frames. debian@BeagleBone:~$ sudo airodump-ng wlan0mon CH 11 ][ Elapsed: 13 mins ][ 2024-07-22 16:22 BSSID PWR Beacons #Data, #/s CH MB ENC CIPHER AUTH
