Yes, this is a firmware problem. But unfortunately this is a really
old hardware (6 years old) and we don't support the firmware anymore.
I'm sorry, but there is really nothing we can do.
I hope the driver manages to recover properly and WiFi continues to
work on your machine without much disturbance when this happens.
