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. > > Do you have a sniffer?

I could put tcpdump on my system, but I think I can not monitor wireless traffic with it, or can I? José Gonçalves
