Thanks for your response.
By "not interpreted" I meant that the packets all went to and from , rather than any mirror.

The main problem with tcpdump is that there are millions of packets
from the rest of the family using the same WiFi access point.

I'm sure you are right.
I tried changing the servers in /etc/resolv.conf , 
but that made no difference.
