Re: Newbie questions

Hi Peter, others

 Thanks for the log outputs. That gave me the pointer to look carefully 
into the /var/log/messages for cardmgr. I saw that the commands are not 
executing properly for some reason. The "wlan-ng" which is in /etc/pcmcia 
is probably the source of the problem. Nothing after that works.
For an orinoco card, it works fine, of course.

Then, I did the following

cd /etc/pcmcia
./wlan-ng start wlan0

Voila !! 
It works like a charm.

Not sure why the problem is occuring. I need to investigate further. In 
the meanwhile, if you or anyone has any pointers, that would be welcome

Thanks
Vikram

See the cut-n-paste below for the problem, and then the post-fix
