Thank goodness. I've been having pretty bad intermittent wifi drop outs on all our iOS devices in the house with our new Airport Time Capsule. Can't wait to install this fix after work.
I'll share a story with you. About 2 or 3 years ago I suddenly started having a really nasty dropout problem with my iPod Touch, my iPad and my iPhone on my wireless network. My Macbook Air was not dropping at all.
I did all sorts of troubleshooting over the course of about two or three weeks. I completely wiped my Time Capsule and reconfigured it. I reset one or two of my iOS devices. I tried reserving IP addresses. I was about to pull my hair out. I could see the devices on my Airport Utility logs, reserving, then losing their IP addresses from the DHCP server.
While standing in front of my bedroom dresser, just on the other side of the wall from my TC, I was staring at the screen of my iPod Touch as it continually rejoined and dropped its wifi connection, at my wit's end. I casually, nearly absent-mindedly reached over and dragged a set of earbuds off of the top of an internet connected blu-ray player that was on the dresser. Suddenly, as soon as I moved the earbuds my iPod connected to the network and held its connection. I checked my iPhone and iPad, and they were both locked in, also. I looked at the logs in Airport Utility, and the drops and rejoins had completely and suddenly stopped. It never happened again.

OK, I'm far from being a networking expert, but for the rogue client issue, doesn't clicking on the router in the current version tell you that?
That it does. But it doesn't tell me all network attached devices (such as wired connections) and it doesn't give me IP addresses so that I can verify against devices that don't have friendly network names (and can't be configured with them).
