On top right corner, the actual scan frequency is shown: For I test I modified the status display a little bit to show only the scan frequencies: The stay time on a channel depend on the count of the targets. The more targets, the longer the stay time: Attached the modified version: Just replace replace the original version by this. Compile it (ignore the warnings) and run it to confirm all frequencies have been scanned. |

The new status display is highly optimized for speed. If there is nothing or no change, it will display nothing. |

Bahhhhh, something changed and I do not know what it was, it seems to want to scan the whole frequency range now. That was very odd. |

Default is 1a, 6a and 11a (in case of no option). |

that makes sense. Epic...... it seems that -F becomes a very important flag. |

You would also need to run the -F flag during an --rcascan for my wifi card to scan the 5Ghz networks. |

Correct. |

Usually you don't need to scan all frequencies, because default configured 2.4GHz APs are located on a few default channels (1a,6a,11a). |

A CLIENT transmit PROBEREQUESTs to find an AP it connect to and hcxdumptool responds to this REQUESTs. |

hcxdumptool is doing this by default (capture all EAP data) and hcxpcapngtool -I will store them to a text file. |

Hi ZerBea,
I'm seeing something which I don't fully understand....it is probably just my lack of understanding of wifi protocol, however;
I have set the 'iw reg' to AU for Australia. If I run the following command it will run the scan on all frequencies. (2.4 and 5Ghz)
sudo hcxdumptool -i wlan0 -w test.pcapng -F --disable_deauthentication --disable_beacon --rds=1However, if I run the following it looks to only scan on ch 1, 6 & 11 on 2.4Ghz and not push into the 5Ghz range.
sudo hcxdumptool -i wlan0 -w test.pcapng -F --rds=1Is this normal behavior?
