I currently have a WRT610N and it gives me a ton of problems. I've never had as much trouble with a Linksys router in my life. I'm a big DD-WRT fan and I try to keep it updated, but I just keep having continued problems from it, and the original firmware gave me even more problems. I've been eyeballing the Airports for a while now, and I've been considering getting an extreme, but I am also considering a Time Capsule. My current setup is a mac mini server sitting on my network with a drobo connected to it. So I'm not sure if I'd get a performance gain from getting a Time Capsule or not. I have been looking into the airport extreme though, and I saw something about an update in October to the hardware. Does anyone have any more specific details on this? The loss of one ethernet port on the airport from the linksys will be somewhat of a pain, but I can figure something out for it.
