Hello,
I have are my last reboot problems with my wifi adapter.
The stick is at an old Cubox. The stick has a while to work, it must have changed a bit lately (updates). Unfortunately I can not say exactly what. I have regularly installed the updates yesterday and I had to restart because of a problem.
