A general philosophy or rule of thumb here at Unplggd: If you can avoid wires without degrading quality too much or having to sell a kidney, do it. Here's a quick and dirty guide to get everything in your home wireless - from the Internet to streaming audio - so you can spend more time worrying about the dog, rather than trying to avoid the trip hazard strung across your room.
- WiFi cards on laptops, desktops, gaming consoles, everything.
- Get a wireless router
- Get a wireless bridge (it really is just a second Wi-Fi router that connects to your main Wi-Fi router wirelessly and shares the connection)
- Place the router as high as possible (no routers sitting on the ground, please)
- You can actually boost your cell phone signal with a few tools
- Wireless HDMI isn't mainstream yet, but you can still get it if you can afford it
- Wireless sound via Airport Express, Apple TV, or Audioengine W1
- Wireless printing via Poloplug or wireless bridges with USB printing support
- Wireless photos via Eye-Fi SD cards (just not for iPads)
That said, if we had to choice to wire up our house, we'd probably do it in a heartbeat. There's nothing that compares to being able to stream movies to Boxee via gigabit ethernet at 1080p without ever having to deal with lag, drops, or other weird technical issues.
