The way you mentioned works since ages, most likely since win95 or nt. If you want to use Linux on the same box you have to get rid of suspend 2 disk (hibernate in ms speach) which is default now, same way for cmd then: "powercfg -h off" - i never looked for a menu to find that, much faster that way. Btw. mac filtering is pointless. It is just a waste of time to enable it, mac adresses are always shown in traffic so in monitor mode you see that without problems. As you can change the mac within seconds thats no security improvement. Better enable only wpa2+aes(ccmp) with a longer passphrase.
