I live in a 2 story home (plus basement). Today I have an Asus N66U which has been excellent, I have been really pleased with it.

It is upstairs on the floor in a bedroom with a cable jack next to the cable modem....so that I can have a network cable run across the hall to my office where my desktop uses wired networking (which I like). This setup provides solid coverage through the whole home.

During some recent renovations I ran cat6 and Rg6 from the basement to the attic...and my wired networking needs will be increasing upstairs.

My plan had been to run RG6 from the demarc in the basement, like 15' to the center of the house (in the basement) and mount the cable modem, and the N66U basically on one of the floor joists for the first floor. This will allow me to use all the cable jacks in bedrooms and rooms around the house for my dish tv system if I want to, and also keep the whole router/modem stuff completely out of sight. I also expect it would provide excellent wireless coverage to the first floor of the house but probably weaker coverage upstairs.

I would then connect one interface on the N66u to a small gigabit switch I purchased, up in the attic. From this switch I have CAT6 run to the bonus room entertainment center so I can connect streaming media and gaming devices with wired gig connections, I can run CAT6 drops easily into an upstairs office or bedroom as needed (drop down from attic)...but I was also thinking I should add a wireless access point to ensure ample signal coverage across the entire upstairs (includin the bonus room which is at the far end of the house and would be a little ways away from the basement wireless router).

So my question is mainly....what wireless AP should I put in the attic?
Will any AP give me a setup where devices will seamlessly switch from the weak signal coming from the basement to the stronger signal in the attic when you walk upstairs?
Will any AP or antenna setup allow people connecting upstairs through the attic to basically be connecting to/through the main N66u in the basement? (This is really a segmentation question as I would like to keep wireless traffic separate from my wired, and SSIDs separate from one another....would rather not just dump everyone connecting upstairs to the attic AP onto the LAN)
If the recommendatoin is just to put any old AP in the attic...any reason I should or shouldnt just get another N66u?
Do any of these answers change if I am open to replacing the N66u as well?
 
Solution
1. The basement is the single worst place in the house to propagate a WiFi signal
2. The attic is second worst.

The basement sucks because signal does nto travel vertically too well. Plus, the cement walls.
The attic is also bad. Again the vertical, and unless it is well insulated, the attic gets way too hot.

Next, the handoff. Consumer grade equipment does not handle handoffs well. A device likes to hang onto a signal, even when another is closer and better. Only when the first is REALLY unusable does it fail over to the 'better' one.

A single good quality AP in the center of the house may work a lot better than 1 in the basement and 1 in the attic.
