Mike - I had a detailed discussion w/ BillyIII when I set up the router on my Rogue. He suggested decreasing the power output of the router, and setting it to channel 6, in an effort to minimize interference w/ the Rogue. I dunno if that discussion is still on ATC, but you may benefit from a search. Your rogue setup menu will have a section for adding hotspots, and the ability to choose one a 'priority' . . . it should also automatically pick up one on that list when in range (but it doesn't seamlessly switch, like a cellphone does.) On my Rogue, this feature was part of a firmware update package, not on the out-of-the box firmware - but my Rogue was 'new' two years ago. . . so you may have that feature.
Like Dave, mine is all 110VAC - I'm using a cheap NetGear router.
