I am considering moving from Vodafone cable to [Spark] UFB. As someone who is heavily invested in Apple's eco-system, including an Airport Extreme router and one Airport Express, I want to make sure that any transition is as seamless as possible. However I recall reading on Geekzone somewhere that there were limitations/issues in such configurations. My search-fu has let me down and I can't find any such a reference. Can someone point me to discussions on issues moving to UFB with an Apple router and Airport express.
