Re: wireless access point IP address

[Frank Moss <frankmoss1950 () gmail com>]

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.
