The first ten minutes of a drop

A wireless drop is diagnosed from its timestamp, its scope, and the logs of the network, the vehicle, and the fleet manager lined up on one clock, so capture those first and answer the triage questions.

The first ten minutes of a drop

A drop is diagnosed from its timestamp, its scope, and three systems' logs lined up on one clock.

Capture now

  • The exact time of the drop, and which clock it came from.
  • Who dropped: one device, one model, one area, or every client on one access point.
  • The device's model and firmware, and where it was on its route.
  • The access point log for that minute: radar, channel or power change, deauth reason.
  • The client's own log for the same window, including who sent the deauth.
  • The fleet manager's record of the same moment.
  • The authentication server log: a new request from the device at the drop?
  • The management audit log, access point uptime, and switch port log for changes or reboots.
  • How long the drop lasted, and whether recovery needed a person.

Then answer the triage questions
