Hopefully there will be an update to improve the reliability of connections for 10.5.x. Since buying the Airport Extreme earlier this year I have experienced very unreliable internet connections (constant drops) compared to my previous linksys router (and every other router I have owned). My experience with this router has made me regret relying on Apple for something as basic as a router. I will unlikely buy another router from Apple in the future unless their quality/reliability for accessories improves significantly for a prolonged period of time. The quality of firmware/software releases over the past year or so seem to be rushed to meet deadlines rather than making quality the most important benchmark prior to release.

Maybe they could also fix airport express so airtunes works when you are using a Timecapsule as your primary router.

Thanks for the idea of unplugging when not using. I am going to put an old-fashioned plug-in timer on my router to turn off at night. This may clear up garbage that might be somehow collecting during the day and causing problems.

Now as long as I don't get insomnia and wonder why I have no internet connection at 3am.
