Wireless is the way to go. I've got mine and my kids' computers networked plus their X-box. Also have several wireless security cameras that I can access from work via the web. Neat.
Yup. Wireless is the way to go these days, for sure. Actually, I have a hybrid system in my home. My wife's work computer and my work computer are hardwired to a router. Everything else is wireless.
There is one advantage to hard-wired networks. They don't broadcast the network and they are solidly faster all the time. Still, for most purposes, wireless is just fine, as long as you have decent protection installed.
A funny note, though, on all of this. There's a guy across the street from me who has a bunch of wireless stuff on his network, including cameras. Trouble is, his network is open as a library. When I got my new Dell notebook and turned it on, the first thing I saw was this guy's unprotected network. Took me about five minutes to start looking through his cameras. One was in his bedroom.
Uffda! I had a little chat with the guy and we fixed up his password protection for his wireless network. He literally did not have any idea that anyone else could access his network.
I notified him of his risk by printing a little note out on his printer from my notebook.
Take your notebook and drive around neighborhoods in almost any town. It's amazing how many unprotected wireless networks there are out there. Funny stuff.
