Hum. I never considered RF problems because I'm testing this module with a 
Jorjin's development kit, so I was considering that Jorjin knows how to make PCBs 
for RF. Also seeing that when I remove the antenna the AP signal strength changes 
from -51 dBm to -73 dBm was a signal to me that the RF was OK.

I have a text console only system. I could put tcpdump on my system, but I think I 
can not monitor wireless traffic with it, or can I?
