The reason I go w/Linksys wireless is because the remote computers have adapters that are on USB cables, and the receiving unit can be moved around a little bit for a better signal.

In my experience, despite all the advances, wireless is still occasionally very buggy. You should buy the router and remote units from the same manufacturer, at the same time, to make sure you have the same compatible technology.

I know wireless is supposed to be the end all and be all of modern computing, but in my experience it can be very buggy, especially in some of those ancient houses we have here in Virginia (1600 AD) and England (1100 AD), houses which have God-only-knows-whatever substance in the construction blocking the signals.

Linksys also sells a booster that helps with difficult signal situations. At Fort Belvoir, we had one computer that was two stories up from the router, and we could only get it to work 100% of the time when we had the booster connected.
