While auditing the security of my wireless network I decided to take a peek at what airodump-ng could display.

This is what it outputs:

BSSID               PWR Beacons #Data #/s  CH   MB ENC CIPHER AUTH ESSID
xx:xx:xx:xx:xx:xx   -85  0       52     0   123  -1 WPA              <LENGTH:0>

However if I look at my actual network through my computer's wireless network utility:

SSID: Virus Net
Channel: 6 
Network Type: Infrastructure 
Encryption: WPA(2)-PSK AES 
BSSID: xx:xx:xx:xx:xx:xx  

Not that I mind, but what's with the strange behavior in airodump? What does length:0 mean and how is my network on channel "123" with -1 MB?

I get this when the SSID is masked. Are you broadcasting the SSID or is the network meant to be 'hidden'? PS: the power level looks really low for decent capture –  James Jun 5 '12 at 1:41
    
No, it's broadcasting. I'm not sure why airodump doesn't pick it up. As for the power level, it's suppose to be that way so people have a harder time getting in from outside my building. –  에이바 Jun 5 '12 at 1:44

have you used the --ignore-negative-one command? –  James Jun 5 '12 at 1:51
    
--ignore-negative-one is not an option for airodump-ng. –  에이바 Jun 5 '12 at 3:40
