David, others

 Thanks for the response.
 I do have ifcfg-wlan0. But that is only for setting up the IP 
configurations once the wlan setup works fine. I have a problem with the 
setup itself. Notice what I get

#iwconfig wlan0

  wlan0 IEEE 802.11-DS ESSID:""
  Mode:Auto Channel:0 Access Point: 00:00:00:00:00:00
  Bit Rate:2 Mb/s Tx-Power:2346 dBm
  Retry min limit:8 RTS thr:off 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

See the values for Channel, AP, Tx-Power. What does a channel of ZERO 
mean. What is a Tx-Power of 2346 dBm ?

But given this configuration, scanning works fine.

Also, if I were to use the same card (linksys WCF12 Compact Flash with 
PCMCIA adapter), but use the orinoco_cs driver instead (which will be used 
if the prims2_cs is not loaded), then the card works well. It maps to the 
nearest AP, and if I config it in the ad-hoc mode, it does it and 
communicates with peer nodes over ad-hoc

The question is why the card does not even get initialized properly. 

Has anyone successfully made a linksys WCF12 card work with the driver.

Are there some prism2_cs cards that work without absolutely any problem 
with the linux-wlan driver ? I don't have to stick with the linksys. It 
was the only one I could get my hands on, but I can switch if I have to. 

Any help would be welcome. I can send in more details if desired.

regards..
Vikram
