Nice read Shawn.
People need to understand that WIFI isn't magic. Going through two or three walls and expecting a perfect signal isn't reality. My tests indicate that anything more than two walls will give you average signal strength but it will be far from optimum, three walls will be marginal at best but there are other factors involved like the density of the walls and many other factors.
Installing access points in the ideal locations is what makes WIFI work best. Expecting to have a good signal at the other end of the house after going through a bunch of walls is pure fantasy but people still seem to think it's possible.
Another important point I'd like to make that the article didn't mention. Using the 802.11n Only setting with AES encryption is the only way to achieve full wireless N speed of 300Mbps. Using the mixed settings or using the older and slower TKIP encryption you can't achieve full wireless N speeds because the router needs to slow down it's signal in order to talk to slower wireless standards. Of course you can only do this if all the clients are using wireless N.
Even with this strong signal strength and high speed of this connection if you don't look around for a clean channel you may notice dropped packets and skipping video streaming so channel selection is very important.
