Unfortunately, I don't exactly have a newer home.
My house was built in '52 and I think I have a cable connection in 4 rooms. I don't have a need for wireless since I have only one desk top now.
My wife has a lap top but only uses it away from home (she travels frequently on business) Wireless is nice and for your wife's lap top sounds ideal.
Now, I will interject my own question that someone may be able to answer: I haven't had a land line phone in several years and never plan on having one. I wonder if I could get the phone company to come out here and remove their ugly wires leading to my house?
