This is a great computer except....after a visit from the local cable company to inspect my internet and two trips to replace my cable router and wifi router, I search the internet for the make and model of the wifi adapter to find out there are know issues with this card but lets put it in a machine anyway.  I am paying for 200 meg service and am only getting 20-30 meg speeds because of this.  Too much of a hassle to return the machine.  Acer should automatically send any customer buying this machine a respectable USB wifi adapter to make up for the junk that is on board.This would easily be a 5 star rating if I could use the machine to its full potential.
