I got the wired connection to the LS9 working eventually, and once I figured out that I was using the wrong port on the Router, I got a wireless connection running. I even managed in running Windows in Parallels emulation.

There are great instructions on the ProSound Web forum for it: LS9 – Setting Up A Wireless Router.

I think Seamus, the manager of The Quays was impressed with me EQing the balcony speakers from the laptop, and may get a dedicated one.
