you can also change it via command line
powercfg...
but YEs you should be able to some changes under advanced settings
does disabling and enabling the device work after come out of sleep?

If that doesn't work it could be hardware related, if that does work then its windows not waking it up on wake up

remember sleep is still on using a small amount of trickle power
hibernate is off with sysem state saved in memory

does either effect wifi same way?
