This is with me connected to a wireless:

lo        no wireless extensions.

eth0      no wireless extensions.

wlan0     IEEE 802.11bgn  ESSID:"UTDGuest"
          Mode:Managed  Frequency:2.412 GHz  Access Point:
26:01:01:78:93:9B
          Bit Rate=0 kb/s   Tx-Power=20 dBm
          Retry  long limit:7   RTS thr:off   Fragment thr:off
          Power Management:off
          Link Quality=70/70  Signal level=-30 dBm
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:0

This is when I deauthenticated:

lo        no wireless extensions.

eth0      no wireless extensions.
