hcxtools - solution for capturing wlan traffic and conversion to hashcat formats

Take a look at the measured EAPOLTIMEs . This values give you some clues about the stay time.
In automatic mode, hcxdumptool check traffic on a channel every 250000 usec. If the channel is empty, it moves to the next entry from the scan list. Targets in the near field are attacked channel overlapped. In case of traffic on the channel, it stays up to the default stay time (5 seconds) on the busy channel.
If you want to override the automatic, 2 seconds should be ok. In that case hcxdumptool will move to the next channel after 2 seconds, regardless of the traffic on the current channel. Good if you expect much traffic on a channel. The check interval of 250000 usec remains untouched. That means hcxdumptool will leave an empty channel after 250000 usec.
Please keep in mind:
The stay time on a channel doesn't depend on your driving speed. It depend on the (expected/real) traffic volume on a channel.
