switching on wireless after minimal install: f16

[Ranjan Maitra]

Hi,

Just playing with minimal install: I was able to install minimally.
Question: how do I switch on wireless?

Playing last week using wired, I simply did: 

chkconfig network on
service network start

but with wireless, I get 

Startnig network (via systemctl): Job failed. See system logs and
'systemctl status' for details....
[FAILED]

Any suggestions?

TIA and best,
Ranjan
