Between my Xbox 360, HD DVD player, Blu-Ray player, and HD Homerun all needing a Ethernet connection over at my HDTV, I went and got a DLINK 5 port Switch. I made my own Ethernet cables as I needed short ones, less cable clutter also it's a green switch so lower power needed for shorter cables when in use and when not in use, no power at all. So the 4 devices are plugged into the switch and the last port is run to one of my Router ports. It's basically like plugging the hardware directly into my Dlink Router. Nothing to configure with the switch, it's basically Plug and Go.
I'm not a fan of wireless connections. Sure for some things like a Laptop that you may use from one place to the next a wired connection would be a hassle, but on hardware that sits in one place. Wired is just so much more Reliable, More secure, Faster. It just works. Once I had it all setup and working I haven't had to do a single thing since. It's been 100% Reliable. I know sometimes wired is virtually Impossible to do for some people, then again, with a little effort, maybe a lot of effort, once it's done and wired, you'd wonder why you hadn't done it already. There's almost aways a way. Lots of different tricks that's possible.
There's also Powerline Adapters, and Cable adapters to get a wired connection also, not as good, but still generally better then wireless. My DLINK DGL-4300 router is wireless, but currently the only device I use wireless sometimes is my PocketPC, and soon a iphone. Time to Upgrade my phone.
