Let the hive mind of Engadget get that for you.
"I'm pretty much a complete noob when it comes to camera stuff. My wife loves to take pictures, though. So much so that she literally wore out her first point and shoot camera, and the Kodak Z712 I bought for her less than two years ago is starting to act up as well. To compound the matter, we are expecting our first born sometime next year. I fear the Kodak just isn't going to cut it any longer. What would be the best starter DSLR to get? She hates missing photo opportunities due to camera 'lag' so speed would definitely be at the top of the list. Photo quality and features would be next. Price should be no more than $800. I'm not interested in video capabilities."
My wireless N router (Belkin) is great for my wireless N enabled laptop (which is what I use in the attic as that's where my bedroom is located and my router is in the living room).
On another note, I have wires going from the living room all the way to the attic for my PS3 and Xbox 360 (I bought 2 x 30metre cables and just nailed along the floorboards)
