Here's your optimization solution: wire everything. Anything you plan on using that has an ethernet port should have a cable going into that router, even if you have to get another switch to make it work. No matter what people say, you will find some way to cause interference or a dead zone, or just get crappy bandwidth over wireless, and depending on your living situation, you may be competing with multiple other wireless networks as well, increasing saturation, not to mention potential interference from microwaves, cordless phones, or other devices operating on the 2.4 or 5 Ghz spectrums. If you have the time and the cabling for it, wiring is always going to be more optimal than wireless.
