Ad-Hoc setup is not working

I want to create the adhoc network between two BBBs and two TP-LINK WN722N v3. I don’t really know why but they show different result when I try put them both in the Ad-Hoc mode:
BBB1:

wlan0 IEEE 802.11bg ESSID:"" Nickname:“WIFI@REALTEK
Mode:Ad-Hoc Frequency:2.412 GHz Cell: 02:11:87:92:DE:30
Sensitivity:0/0
Retry:off RTS thr:off Fragment thr:off
Power Management:off
Link Quality=1/100 Signal level=-99 dBm Noise level=0 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0

Another: BBB2:

wlan0 IEEE 802.11bg ESSID:"" Nickname:“WIFI@REALTEK
Mode:Ad-Hoc Frequency:2.412 GHz Cell: 02:11:87:49:FE:FE
Bit Rate:54 Mb/s Sensitivity:0/0
Retry:off RTS thr:off Fragment thr:off
Power Management:off
Link Quality=21/100 Signal level=-66 dBm Noise level=0 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0

The light on the USB on second BBB is not showing up, but I still can connect it with wifi if I want to. Can anyone facing the same problem??

Thank you!
