Keep a wlan active without Access Point?

[Ravindra Wankar <rwankar celoxis com>]

I have a wireless connection with a static IP address 192.168.0.100. 
Everything works fine when I'm connected to an Access Point. Without the 
access point ping returns "connect : Network is unreachable". Using 
127.0.0.1 works, but I'd rather have the static IP accessible. The 
routing table is empty. How do I setup Network Manager so the IP is 
available?

Thanks.
