Q: Airport Extreme (5th Gen) fails when changing settings.

Unfortunately, I'm not in front of my router right now. It's usually a pretty generic message "Something's gone wrong" "Unexpected Error" kinda thing. And then I get the yellow caution sign in Airport Utility. So I unplug the router from power, plug it back in and after it boots up all the changes are there.

I'd test it from the office (Back to My Mac works fine) , but I don't want to knock out my home network all day. I'll post a more accurate error message when I get home.

The message is as follows :

"an error occurred while updating the configuration"
