@Eagle_cz It flushes your entire adapter settings. Mostly the cause of a 00 MAC address is a faulty network adapter or tinkering with it yourself. The flush will fix this by resetting the 'faulty' values and reapplying the correct MAC as it had always been. A 00 MAC address is not allowed by vendor standards so it has to be tinkered with. I never said it will give you a *new* MAC, it will restore your old, normal MAC.
