So wifi is on now? On my acer 5742G I see above upper left of keyboard:
power on button (blue light), right side of it: harddisk light (flashing blue if accesing disk), right side of it: wireless icon (color orange).

You see the wirless icon there or somewhere else? It changes color if enableing/disabling it using fn+f3?

ipconfig looks fine
device manager looks fine
if wireless icon is orange above keyboard it's fine.
just enable wireless adapter in network centre (change adapter settings) and it should be fine
