wireless is good! i use it too in my HP laptop in my house, i buy a wireless 4-port router and now i have internet to my laptop and personal computer...
I dont think so wireless is slow! Only if your internet connection is slow and your connectivity with access point is low then your conection is bad. My internet connection is just 2mb/s so with low connectivity which is like 5-10mb/s i can use my internet great, but if i have like a 30mb/s and my connectivity just 10mb/s i can only get 10mb
But i don`t have so good internet just 2mb/s
