Bart, thanks for your answer.
The only thing I have that might be used is the MAC address of the access point. When I switched arp requests on in wireshark, I dont see any arp-request from/to my acces point. I see the one from the central router (ISP). Is there any way I can detect its IP address from its mac address?
Frank.

hello frank,
if your a bit lucky you should be able to, most devices are rather
chatty and when you hook them up to a device with wireshark and just
check what it is sending you usually end up with the ip or the subnet
of it (ARP requests for its gateway are something to look for). though
if it changes IP address with a different ISP then i would assume it
gets the IP via DHCP from either the ISP or your residential gateway,
in any case it would then be in the range of your other connected
device i assume.
good luck,
bart
