calig Posted August 18, 2011 Share Posted August 18, 2011 Hi everyone, Just joined today because of my interest in wireless. My curiosity has been aroused by a local AP that is not transmitting an ESSID. It also is neither transmitting beacon frames nor data. The channel shows a negative one, as does the power. Facts: 1. I know this AP is nearby because, before they hid the ESSID, the power output was fairly high. 2. Airodump-ng shows -1 channel, -1 power, and a hidden ESSID, although the BSSID is visible. Neither the channel nor the encryption scheme are being transmitted. 3. Neither beacons nor data are being sent. I can determine the correct name of the ESSID from the probe field in airodump-ng but that is all. 4. All attempts in aireplay-ng to dissociate the client fail with the message that "No such BSSID" is found!? 5. Kismet, on the other hand, does not even see the AP. 6. Loading the .cap file in Wireshark reveals no information about those packets for which the source, or dest, is the AP. Can anyone give me guidance on how I can learn more about this? Thanks, Quote Link to comment Share on other sites More sharing options...
Infiltrator Posted August 18, 2011 Share Posted August 18, 2011 It sounds like it's been turned off? Quote Link to comment Share on other sites More sharing options...
hexophrenic Posted August 19, 2011 Share Posted August 19, 2011 Actually, it sounds more like a driver incompatibility between aircrack and the wlan card (with -1 on stuff). Do you see any other APs (other than the one you might be connected to)? Quote Link to comment Share on other sites More sharing options...
calig Posted September 11, 2011 Author Share Posted September 11, 2011 Just to close this topic. Apparently the AP was malfunctioning as it came back online a few hours later. Everything was normal then. Thanks for responses. Quote Link to comment Share on other sites More sharing options...
