[citation][nom]supertrek32[/nom]No matter how secure you think it might be, never trust wireless networks for security. If it's sensitive data, just wait until you can plug into the wall. You never know, so if you're paranoid enough that you truely want all that encryption, just use good ol' ethernet cables.[/citation]
Now... in a home environment - sure, that's fine - just make sure there's hook-ups available. For businesses though... Ethernet, sure, but having NAC with it is the way to go. It's a pain to setup, but very effective means of truly securing what devices connect where, when and how.
