Ok so iv just started using backtrack 4

am running a advent roma 2000:

Advent Roma 2000 Intel® Celeron® 900 (2.2 GHz),
Genuine Windows® 7 Home Premium,
3072 MB ram
Hard drive: 32ogb

Wireless Built in card : " Realtek semiconductor co. ltd RTL8187SE wireless LAN controller (rev 22) "


I have been trying to pen test some local wireless netowrks, the problem is i know am in range of a wireless AP because windows 7 displays it as a internet connection option but when i run the following codes bellow i cannot find the BSSID.

Am i doing something wrong with my codes? (heres what am doing)

Booting up from the live CD
chooseing the first boot option (frame buffer something 1024x768)
then use command: "startx"
then the GUI loads
I then open a command prompt
i enter "airmon-ng start wlan0"
i get conformation the wcard has turned on monitore mode
i then type "airodump-ng wlan0"
all i see is the titles like

BSSID PWR Beacons #Data #/s CH MB ENC CIPHER AUTH ESSID

i am not getting any of this

BSSID PWR Beacons #Data #/s CH MB ENC CIPHER AUTH ESSID
00:1C:58:AE:C3:01 -60 124 1 0 1 54 WPA2 CCMP PSK Network

BSSID Station PWR Rate Lost Packets Probe
00:1C:58:AE:C3:01 00:1B:66:AD:C6:00 -57 0- 1 48 Network
