Message-ID: <55D4D406.5000603@candelatech.com> (sfid-20150819_210756_303353_84D6844F) Date: Wed, 19 Aug 2015 12:07:50 -0700 MIME-Version: 1.0 Content-Type: text/plain; charset=utf-8; format=flowed Sender: linux-wireless-owner@vger.kernel.org List-ID: I have a commercial AP that is using a CM9 ath5k radio (evidently, I could be wrong) and it has the ability to do a constant transmit of raw noise (RF probe shows noise, but a monitor-port sniffer does not see any frames from the CM9). I don't know the low-level details of how it is doing this, but I suspect it is using something like madwifi for a driver. Does anyone know how this can be done with modern software and ath5k or ath9k NICs? Thanks, Ben -- Ben Greear Candela Technologies Inc http://www.candelatech.com
