i hope this isn't a stupid question but...

im hopefully getting this laptop tonight:

does vista premium have a dvd player feature? it probably does but my mind is saying for the price it might not even have some 'less then basic' things.

and I really am in the dark about wifi.

my computer is in my living room, the modem (i think) has an antenna on it. my brother said his friends have used wireless in my house before but im wondering how far it goes. my modem/computer is about 40 feet, if this modem thing actually has wireless will i be ale to get it in my room? (that would be WONDERFUL news )
