I surely hope this question is not a duplicate of another; I had difficulty finding a cut and dry solution for this on my own, so I thought I might have some luck sharing it with the Hive Mind of collective human consciousness that is the Stack.
My goal is simple: I seek to broadcast a signal within a very small space (approximately 1000 square feet) that will block wireless access to a specific Access Point. In doing so, I am hoping to avoid blocking access to any other access points in this airspace. There is one specific unsecured Metropolitan Area Network in my area that represents a potential security liability.
I have the requisite authority to broadcast a signal within a short distance to essentially "scramble" this particular signal. I do not, however, have the capacity to make any changes to the ACTUAL WiFi access point in question; therefore, I cannot manually set up firewall rules or a MAC address filter to the AP that needs to be masked.
I do, however, have control over all other access points in this airspace, and can change their ESSIDs, channels and other configuration at will. I can also set up additional APs if need be, in order to try to close off access to this network.
One method I had considered would be to set up an BackTrack instance, or DD-WRT router, or HyperWRT/Tomato router, with the goal of aggressively intercepting wireless access point association requests for the wireless network that I want to block... I have not given this a go, yet, as I had hoped to confirm that it is the correct solution before attempting to employ it.
Any help that can be offered is greatly appreciated.
