I'm another swayed towards a wired LAN setup.
I only say this because my efforts to get a wireless system going
reliably never really panned out.
I'd put most, if not all of that down to ignorance of all things
wireless.
Anyhoo, my wired LAN from house to dome has worked fine for a few
years now, I drive the scope over the LAN from inside using RD and Win XP.
I usually run the imager capture program, Cartes Du Ciel as the scope
drive interface and Bartels Scope exe on the Dome laptop (connected to
the dome PC via serial 3 wire).
I still have to manually go outside and nudge the dome azimuth by hand
every half hour or so.
A wired LAN could have a disadvantage over a Wireless LAN in that
any nearby lightning strike or static discharge could kill everything inside your house via
the dome or vice versa I suppose.
