Can't connect to wireless network; Asus P5B wifi

I'm building a system with an Asus P5B Deluxe WiFi motherboard which uses a realtek RTL8187L chip.  This is a USB device.  I cannot connect to the wireless network.

I started the card manually, and did an iwconfig, which shows:

wlan0     802.11b/g linked  ESSID:"B12345A" 
          Mode:Managed  Channel=11  Access Point: 00:13:49:79:BF:2B   
          Bit Rate=54 Mb/s
          Retry:on   Fragment thr:off
          Encryption key:off

          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:0

iwlist wlan0 scanning gives:

Cell 01 must be my neighbor's network; Cell 02 is a Zyxel access point I have temporarily set up without any encryption; Cell 03 is my normal access point using wpa-psk.  It looks to me like the card in the computer is recognizing the Cell 02 access point, but I cannot ping it.

Not sure why the signal level is at zero; this remains at zero regardless of where I locate the access point. 

I did an ifconfig wlan0 192.168.27.4 to give an ip address.  It cannot ping anything else on the network, and anything else coming in times out.

I feel like I'm missing something obvious, but can't figure out what it is.  What am I missing?

Re: Can't connect to wireless network; Asus P5B wifi

Can we see set up in rc.conf? use pastebin for larger configs

Think you were having problems starting wlan0up from boot I tried rc.local but it would not start here

Maybe need a startup script in rc.d

Would be handy if anyone uses wireless to just say how they start network ...

Wiki is helpful but a little confusing

wlan0     802.11b/g  Mode:Managed  Channel=3  
          Access Point: Not-Associated   Bit Rate:11 Mb/s   
          Retry:on   Fragment thr:off
          Encryption key:off
          Link Quality:0  Signal level:0  Noise level:0
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:0

Signal is down here though I have not got Antenna connected
