![]() ![]() Probe request has different rssi value which indicate the signal level. See probe request but not probe response.ģ. The attached file is one of sample but I do have other pcap file which I can Many people thinking satellite dont transmit at 2.4 GHz but some regions they have satellite using S-band but not many.Ģ. I have done other investigations on the flight case, the source comes from Satellite. May be you dont follow what I am trying to convey. There are other logic which I dont want to include. I received probe requests and I can see that there are no probe response. The logic is at 32000 ft, and the flight dont have access for wifi and there is no antenna inside the flight. Well, in my region, we do have satellite in S - Band. You haven't discovered something new or interesting nor is ANY of this actually causing you an issue with using wifi. IF IT WAS FROM AN ACCESS POINT IT WOULD BE A PROBE RESPONSE.Īll this tells me is that your understanding of 2.4 and 5.0Ghz wifi is badly and comprehensively flawed and this is the actual issue you have, rather than any issue with the technology. THEY CANNOT COME FROM SATELLITES OR ACCESS POINTS. THEY CAN ONLY COME FROM PC'S TABLETS AND SMARTPHONES. SATELLITES DO NOT SEND WIFI PROBE REQUESTS. It cannot be monitored, sniffed or captured with Wireshark and satellite transmissions CANNOT be seen on a plane in the way you suggest. I have *hundreds* of customers out there using this technology. I do satellite broadband and VSAT communications for a living. ![]() They would never reach the planet from the satellites orbit. Satellites don't transmit on 2.5 or 5.0Ghz frequency. The rules and laws in each regulatory domain will cover things like maximum radiated power, frequencies/channels that may be used and so on. There are others but I am not familiar with them. The ones I am familiar with are USA, The EU and Japan. Regulatory domains are the countries or territories that use the same laws to govern wifi. Some devices allow the user to choose the regulatory domain. It means one wifi device to another.Ĭountry string is the hex value for the regulatory domain set by the device manufacturer and will be appropriate for the country the device is shipped to. P2P usually means peer to peer or point to point. Interference isn't a fixed value so probe requests from the same host in the same physical position can still have different RSSI values. Help me to help you my telling me which packet it is in the sequence so I can look at the same one. ![]() If you want me to look at the same packets you are, I need to know which packet it is. I DOUBT THERE WERE ANY ACTIVE WIFI ACCESS POINTS ON THE AIRCRAFT.Ģ. ACCESS POINTS SEND PROBE RESPONSES NOT PROBE REQUESTS. UNTIL THAT HAPPENS THE TAG MUST BE 0 BECAUSE THE HOST DOESN'T KNOW WHAT IS OUT THERE UNTIL PROBE RESPONSES ARE RECEIVED. A PROBE REQUEST IS A HOST ASKING EVERY ACCESS POINT THAT HEARS THE PROBE TO RESPOND WITH IT'S SSID. PROBE REQUESTS ARE SENT BY HOSTS NOT ACCESS POINTS. What are the MAC addresses of your laptop and phone wifi interfaces?ġ. Do you have a phone with it's wifi hotspot switched on? Is the laptop set up to share its wifi connection? Both would cause Wireshark to receive wifi beacons. You are saying that the SSID you can see that is giving you interference is still present on the flight and you are receiving packets from it? That suggests you are carrying it with you. Which packets are the ones giving you the issue? It's not clear from the capture which ones you are interested in. I can see the interference comes from Satellite. I can see something is not rigth with WiFi packets but I want to know whether anything strange or particular about the For sure there are not beacon frames but what I can see probe request to SSID=Broadcast and for sure there is such SSID on the flight. As result, I received WiFi Packets.Īnything strange of this pcap. I use my Laptop to check whether I can receive Wi-Fi packets or not. On the way flight back from Medan to Singapore at 32000 ft. ![]()
