some interfaces require being forced shutdown and tuned back on again, otherwise they just seem to be up but they not initialized correctly. and of course having the newest wifi drivers helps 90%
Pretty sure i read somewhere that ensuring wifi card is enabled in bios and recognized ok. (wifi usb dongles in bios -- where power management of usb devices in general is managed in bios)
iwconfig command should return the name of your interface on terminal.
Personally I would alwys recommend this read below...

Also important some machines dont support having a active Ethernet connection and connect to a wifi at same time. SO either shutdown the Ethernet interface by issuing iwconfig eth0 or eth1 down.
I also found that enabling link aggregation also works but this must be done manually meaning you can have two nics to be enabled at same time and receiving or transmitting data.

I find these to be indispensable to the learning curve.
