hey, i'm using an airport extreme as my primary router for internet and everything, and i have a airport express set up in my bedroom for wireless music. i've set it up that the express is joined with the extreme so internet (from the lounge room) and music (in my bedroom) all run through one network. i just purchased a printer which i plugged into my airport express to enable wireless sharing, and in airport utility it shows the express is connected to the printer, but while im connected to the extreme it wont let me print to it, however it'll still let me stream music to it. And to make is very frustrating because the networks are joined, it wont even let me connect to just the express to do the occasional printing that i want. can you please help me in working out why i can't print. it's really frustrating!!
