Do USB WiFi dongles capture any data on their chipsets (commonly Realtek or Ralink)? Is it safe to purchase used dongles or to give away used dongles?

Maybe changing your wifi password is good jist in case.



I doubt simple usb wifi dongles have a writable memory that survives without power supply.

The lack of an option to flash/upgrade it’s firmware is a good indication of that.
